Abstract
A TFT array substrate is provided with an auxiliary capacitance that has a plurality of lower electrodes disposed for each pixel in the row and column directions below a pixel TFT and connected to the drain area of the corresponding pixel TFT. The distances Land Lbetween separation areas formed between the lower electrodes adjacent in the row direction and the channel areas of the two pixel TFTs that correspond to the lower electrodes are substantially equal to each other. The distances Land Lbetween separation areas formed between the lower electrodes adjacent in the column direction and the channel areas of the two pixel TFTs that correspond to the lower electrodes are substantially equal to each other. Furthermore, an upper electrode is disposed above the separation areas.
