Abstract

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a unit pixel of a thin film transistor liquid crystal display device, comprising: a gate line extending in one direction and protruding on one side to become a gate electrode, and extending in a direction different from the gate line; A data line connected to the channel is formed, a pixel electrode is formed in a block formed by the gate line and the data line, and is connected to the drain electrode and the other side of the channel, and the charge storage electrode connected to the common electrode is connected to the pixel electrode. Since a predetermined width is overlapped by forming a band around the edge, the charge storage electrode does not occupy a separate area, thereby increasing the aperture ratio of the LCD and increasing the margin of alignment with the upper liquid crystal substrate, thereby improving color contrast. In addition, the process margin during the etching process is also increased, so that the LCD quality can be improved and process yield is improved. Can hurt.
