<p>PROBLEM TO BE SOLVED: To decrease display defects, such as flickers and luminance unevenness, and to obtain proper image quality by minimizing the differences between the effective voltages impressed to liquid crystal layers of respective pixels of the panels of a liquid crystal display device of an active matrix type. SOLUTION: TFTs, lining up along the scanning line direction, are made small in resistance (rs) of the source regions and large in resistance (rd) of the drain regions on the power feed side and is made large in resistance (rs) in the source regions and made small in resistance (rd) in the source regions on the terminal side, with which the penetration voltages generated by the respective TFTs are made uniform, and the occurrence of the differences in the effective voltages impressed to the liquid crystal layers of the respective pixels in the panels is obviated.</p> |
