Abstract
It is possible to decrease block segmentation and flickering due to separate exposure in an active matrix substrate while avoiding decreased aperture ratio, increased parasitic capacity and complication in manufacturing process. A first pixel circuit and a second pixel circuit including a first-type TFT and a second-type TFT, respectively, are disposed alternately relative to each other in both directions of row and column in an active matrix substrate. In the first-type and the second-type TFTs, a pattern misalignment of the drain electrode with respect to the gate electrode in an up-down direction will increase/decrease a gate-drain parasitic capacity Cgd in reverse ways. By disposing these two types of TFTs in uniform dispersion, the increase/decrease in the parasitic capacity Cgd caused by pattern misalignment occurring at the time of manufacture are averaged.
