Abstract: A drain electrode 25 of a TFT 21 overlaps with a gate electrode formed integrally with a gate line 23. A pixel electrode 22 has a main body part formed on a first side of the gate line 23, and an extension part extending in an extending direction of a data line 24 and covering an overlapping portion of the gate electrode and the drain electrode 25. The drain electrode 25 is not formed on a second side of the gate line 23, whereas the extension part of the pixel electrode 22 is formed also on the second side of the gate line 23. Even when a position of the pixel electrode 22 is shifted in the extending direction of the data line 24, a parasitic capacitance between a drain and a source of the TFT 21 is kept constant, because an area of a portion where the extension part of the pixel electrode 22 overlaps with the gate line 23 does not change. With this, degradation of display quality due to a variation in the parasitic capacitance between the gate and drain of the TFT 21 can be prevented.
