摘要

A display device has two data signal lines provided for each column of pixels (α, β, γ). A data signal line (15q) to which a pixel electrode (17a) contained in a pixel (101) is connected via a transistor (12a) and a data signal line (15Q) to which a pixel electrode (17b) contained in a pixel (102) adjacent to the pixel (101) in a column-wise direction is connected via a transistor (12b) are different from each other. The pixel electrode (17a) contained in the column of pixels (β) forms a capacitance (CaP) with a data signal line (15P) provided for the column of pixels (α) and forms a capacitance (Car) with a data signal line (15r) provided for the column of pixels (γ). This enhances the display quality of a display device having a plurality of data signal lines provided for each column of pixels.
