Abstract
The i-type semiconductor layer (AS) and the gate insulating film (GI) are patterned along and in the same shape as the video signal lines (DL) between the video signal lines (DL) and the first transparent glass substrate (SUB1 ). The backlight is disposed on the second transparent glass substrate (SUB2) side. Therefore, signal line reflection of external light can be prevented, improving the display quality.
