发明名称 LIQUID CRYSTAL DISPLAY DEVICE
摘要 <p>PROBLEM TO BE SOLVED: To enable an active matrix type liquid crystal display device of a horizontal field system to display a favorable video by increasing an opening ratio of the pixels and controlling unevenness of luminance in the pixels caused by electric field leakage from video signal lines while improving an yield of an array. SOLUTION: Among plural pieces of common electrodes arranged in a pixel, the common electrodes adjacent to a video signal line are formed from a transparent conductor, and a pattern electrically parted from the common electrode bus bar is formed in the lower part by shifting to the video signal line side. A common electrode not adjacent to the other video signal lines is formed from a transparent conductor. Thus, it is possible to improve contrast by shielding leakage of light near the video signal lines while increasing an effective opening ratio of the pixels, and also make a failure of short-circuiting across the scanning signal lines, and the common electrodes and the common electrode bus bars, resistant to occurring, and improve an yield.</p>
