<p>PROBLEM TO BE SOLVED: To provide a liquid crystal display device having lowresistance signal lines and high opening rate by forming one source and drain electrodes of transparent electrode materials and the other of metals. SOLUTION: An insulating substrate 1 is provided thereon with source and drain transparent conductive films 2 integrally formed with pixel electrodes and source drain metallic films 3 integrally formed with signal wirings and is provided with multilayered films composed of semiconductor films 4, gate insulating films 5 and gate metallic films 6 so as to overlap on the transparent conductive films 2 and the metallic films 3, respectively, at both ends thereof. Namely, the transparent conductive films 2 are made usable for the source and drain electrodes on the pixel electrode side where transparency is required and the metallic films 3 are made usable for the source and drain electrodes on the signal wiring side where low resistance is required like these TFTs. As a result, the production of the TFT-LCD (thin-film transistor liquid crystal display device) having signal lines of the low resistance and the high opening rate is made possible.</p> |
