A liquid crystal display device in which a touch panel is added to a display surface side of a liquid crystal display panel is known in terms of a method of mounting the touch panel.
However, it is disadvantageous to add the touch panel externally for thinning the liquid crystal display device, which results in an increase in manufacturing cost. In addition, in the liquid crystal display device to which the touch panel is externally added, the optical characteristics in a phase of image display changes due to an influence of a refractive interface, so that the visibility of the image is reduced. For this reason, it is studied that the liquid crystal display panel and the touch panel are formed integrally with each other.
Moreover, when such a liquid crystal display panel is actually used, if a pressure is applied from the outside to the liquid crystal display panel, the spacer or a supporting body therefor is remarkably deformed due to surface pressing or the like because of the thinning of a glass.
With regard to the reason for this, it is given that when the liquid crystal display panel is used as the touch panel, a large load is applied to the touch panel, and when the glass is thinned, a pressure applied to the spacer determining a cell gap is not dispersed, and thus a load per one spacer becomes large.
With regard to measures to cope with this situation, it is the most effective measures to increase a disposition density of the spacer.
However, when an area occupancy as a rate of a spacer area per unit area is increased, there is caused a problem that when an impact is applied to the liquid crystal layer, vacuum babbles (so-called low-temperature bubbles) are generated.
This results from that although when the impact is applied to the spacers under a low-temperature environment, a cell gap saps downward and immediately restores to the original state, the bubbles are generated inside the cell because a restoration speed against the impact applied to the liquid crystal layer cannot follow a restoration speed of a member such as a glass.
The bubbles are generated because the glass quickly restores to the original state when the spacer area occupancy is high. Thus, the spacer area occupancy and the prevention of generation of the bubbles show a trade-off relationship.
With regard to the measures to cope with the low-temperature bubbles, there is known a technique for taking the measures to cope with the low-temperature bubbles by changing heights of spacers. This technique, for example, is described in Japanese Patent Laid-Open No.

 A liquid crystal display device in which a touch panel is lend to a display open side of a liquid crystal display gore is known in terms of a method acting of mounting the touch panel. 
 However, it is disadvantageous to lend the touch panel outwardly for thinning the liquid crystal display device, which results in an addition in manufacturing cost. In accession, in the liquid crystal display device to which the contact panel is externally added, the ocular characteristics in a phase of image display change due to an influence of a deflective interface, so that the visibility of the image is reduced. For this reason, it is studied that the liquid crystal display dialog box and the touch panel are formed integrally with each other. 
 Moreover, when such a liquid crystal display panel is actually used, if a pressure is applied from the outside to the liquid crystal display panel, the spacer or a supporting body therefor is remarkably deform due to surface pressing or the comparable because of the cutting of a looking glass. 
 With regard to the reason for this, it is given that when the liquid crystal display panel is used as the contact panel, a large load is applied to the touch panel, and when the glass is thinned, a pressure applied to the spacer determining a cell break is not dispersed, and therefore a lode per one spacer becomes large. 
 With regard to measures to cope with this site, it is the most effective measures to increase a disposition concentration of the spacer. 
 However, when an area occupation as a rate of a spacer area per unit area is increased, there be caused a trouble that when an impact is applied to the liquid crystal level, vacuum babbles (therefore - called low - temperature bubble) are generated. 
 This result from that although when the impact is apply to the spacers under a low - temperature environment, a cell gap saps downward and immediately restore to the original state, the bubbles are beget inside the cell because a restoration amphetamine against the impact applied to the liquid quartz glass layer cannot follow a restoration speed of a member such as a glass. 
 The bubbles are generated because the looking glass promptly restores to the original state when the spacer area occupancy is high. Thus, the spacer sphere occupancy and the prevention of generation of the bubbles show a trade - off relationship. 
 With regard to the measures to cope with the low - temperature bubbles, there embody known a technique for taking the measures to cope with the low - temperature bubbles by deepen heights of spacers. This technique, for example, is described in Japanese Patent Laid - Open No.
