To enhance image quality by preventing reduction in color density while enhancing luminance of a liquid crystal display.

A four-color liquid crystal display includes a plurality of gate lines 121 and a plurality of data lines 171 crossing each other, and a plurality of pixels connected to the gate lines 121 and the data lines 171, each pixel including red, green, blue and white sub pixels RP, GP, BP and WP. The white sub-pixel WP is smaller than the other sub-pixels. Each of the data lines 171 passes between adjacent two sub-pixels, and includes at least one curved portion. The lengths of the data lines 171 are substantially the same. Since the white sub pixel WP is designed to be smaller than the other sub pixels, reduction in color density is prevented while luminance is enhanced, and dynamic video is displayed. Since the lengths of the data lines 171 passing between sub pixels are substantially the same, load difference due to length difference of the data lines 171 is not generated, and image quality deterioration due to load difference can be reduced.
