 scanning line, and the noise may cause a leakage current.
In order to suppress the influence of the noise of the scanning line due to the variation in the potential of the common electrode for display, it is effective that a first gate driver and a second gate driver which are arranged such that the scanning lines are interposed therebetween in the extension direction of the scanning lines may select each row of pixels in a display region from both ends of the scanning lines. However, transistor elements of the first and second gate drivers need to be provided in a frame which does not contribute to the display region. In this case, the size of the frame may increase. When the size of the frame increases, the space of the display region of the display device is limited. Therefore, it is necessary to reduce the number of transistor elements of the first and second gate drivers in the display device.
For the foregoing reasons, there is a need for a display device, a method of driving the display device, and an electronic apparatus that suppress the noise of a scanning line while suppressing the increase in size of a frame. 1. Field of the Invention
The present invention relates in general to a process for preparing acarbose with high purity useful as medicine for the treatment of diabetes. More particularly, it relates to a process for preparing acarbose with high purity represented by the formula (I), which comprises prepurifying an acarbose-containing solution using a synthetic adsorbent to produce a prepurified acarbose having an acarbose content of a predetermined level or more; and contacting the prepurified acarbose with a monodispersed, strong acid cation exchanger, in one step, to adsorb acarbose. 
2. Description of the Prior Art
Acarbose as a glucosidase inhibitor reduces the glucose level in human blood by delaying the absorption of glucose in the human small intestine and thus widely used in medicine for the treatment of diabetes. The inhibitor is obtained by fermentation of Actinoplanes species (see German Patent No. 2,209,832; German Patent No. 2,209,834; and German Patent No. 2,064,092). Many methods for isolating acarbose from this fermentation broth are known in the art.
As disclosed in U.S. Pat. No. 4,062,950, the fermentation broth containing acarbose is centrifuged and the resulting supernatant is decolorized with active charcoal or nonspecific adsorption resins under acid condition, and adsorbed onto active
scanning line, and the noise may cause a escape stream. 
 In holy order to suppress the influence of the noise of the scan line due to the variation in the electric potential of the common electrode for display, it is effective that a first gate driver and a second gate driver which are arranged such that the scan lines are interposed therebetween in the annex direction of the scanning lines may choose each row of pixels in a display region from both ends of the scanning lines. However, transistor elements of the inaugural and second gate drivers need to be provided in a skeletal system which does not contribute to the display region. In this case, the size of the frame may increase. When the size of the human body increases, the space of the display region of the display device is limited. Therefore, it is necessary to deoxidize the number of transistor elements of the first and second gate drivers in the display device. 
 For the foregoing rationality, there be a need for a display device, a method of driving the display device, and an electronic apparatus that suppress the noise of a scanning line while suppressing the addition in size of a human body. 1. Field of the Invention

 2. Description of the Prior Art 
 Acarbose as a glucosidase inhibitor reduces the glucose degree in human blood by delaying the absorption of glucose in the human small intestine and therefore widely used in medicine for the treatment of diabetes.
