Abstract
Abstract A set of pixel regions (P11, P12, P13) having a pixel electrode (12) corresponding to red, green or blue as one unit is arranged periodically in the X direction, and the delta arrangement is constituted by displacing the pixel arrays from each other by a 1/2 period at odd-numbered lines and even-numbered lines in the Y direction. By connecting only the pixel electrode (12) of pixel regions (P12, P22, P32) corresponding to the same color with the same source line (S2), the pixel regions (P12, P22, P32) are placed alternately right and left of the source line (S2). Among pixel regions (P11, P12, P13, . . . ) in the X direction, the relative position of a TFT (11), the pixel electrode (12), a first electrode (C1) and a second electrode (C2) of storage capacitors CS is the same. Among pixel regions (P12, P22, P32, . . . ) in the Y direction along source lines (S1, S2, S3, . . . ), although the relative position of the TFT (11) and the pixel electrode (12) is reversed right and left at each line, the relative position of the first electrode (C1) and the second electrode (C2) of the storage capacitors CS is the same.
