Display device wherein a value of a channel width divided by a channel length of one TFT is greater than another TFT, and a gap between a pixel electrode and a counter electrode is wider for the one TFT than the another TFT |
摘要 |
A display device which can reduce easily the brightness unevenness produced by the insufficient writing of TFT, wherein, the display device having: a display panel which, over a surface of an insulating substrate, includes plural scanning signal lines; plural picture signal lines; plural TFTs; plural pixel electrodes coupled to sources of the TFTs; and a counter electrode, wherein the pixel and counter electrodes are arranged over the same surface of an insulating layer overlying the surface of the insulating substrate, and when a gate insulating film provided at one TFT among the TFTs is thinner than a gate insulating film provided at another TFT among the TFTs, a gap between a pixel electrode coupled to the source of the one TFT and the counter electrode is set to be wider than a gap between a pixel electrode coupled to the source of the another TFT and the counter electrode. |
