Abstract:
A TFT substrate includes drain signal lines which are connected with respective pixels, source electrodes which are connected with the drain signal lines via channel portions of transistors, and pixel electrodes which are electrically connected with the source electrodes. The pixel electrode is, further, constituted of a contact-portion electrode which is connected to the source electrode, an opening-portion electrode which is an electrode in an opening portion which is not covered with a black matrix, and a channel upper electrode which is formed so as to cover the channel portion of the transistor of the neighboring pixel. By extending the channel upper electrode to the channel portion of the neighboring pixel, an area of the pixel electrode is increased, and a line width of the opening-portion electrode is made relatively small. Accordingly, the TFT substrate can hold a stable potential.
