Abstract: A liquid crystal display includes: first and second thin film transistors and a compensation transistor formed on a first insulation substrate; a first gray subpixel electrode connected to a drain electrode of the first thin film transistor; a second gray subpixel electrode connected to a drain electrode of the compensation transistor and a drain electrode of the second thin film transistor; and first and second reference voltage lines overlapping at least one of the second gray subpixel electrode and the first gray subpixel electrode, wherein a pixel area occupied by the first gray subpixel electrode and the second gray subpixel electrode is extended in a first direction, the first and second reference voltage lines are extended in a second direction, which is substantially perpendicular to the first direction, to overlap the pixel area, and one of the first and second reference voltage lines is connected to a source electrode of the compensation transistor.
