<p>PURPOSE:To prevent the incorporation of the defects owing to the rubbing and gap agent of a liquid crystal display having picture element electrodes and wirings connecting to said electrodes, by constituting the display in such a way that the average height in the other region is not higher than the average height of the respective picture element electrodes for the purpose of displaying. CONSTITUTION:An aluminum wiring 55 and a gate part 53 which are susceptible to damage owing to rubbing and gap are made lower than a picture element electrode 56. Therefore, the damaging thereof by the rubbing and the breakdown owing to the concentration of pressure by a gap agent are eliminated. A transistor part 66, a gate polysilicon wiring 62 and a source line 3 are all made low, and have the construction strong to the rubbing. A lower glass substrate, for example, quartz glass is used in this case in the stage of producing the above-mentioned construction; therefore, a hollow construction is made by etching the quartz glass and a transistor is formed on the recess. The similar construction is formed as well by laminating a transparent dielectric material such as polyimide on the quartz glass substrate, and patterning and etching the layer.</p> |
