ABSTRACT:
A thin film liquid crystal display, having a high aperture ratio, is described. Said display has been designed so as to reduce the incidence of short circuits between its various parts.
This has been achieved by modifying the structure of the lower electrode of the storage capacitor. Said lower electrode is formed in the shape of a hollow square, two non-adjacent sides of said hollow square being at the level of the gate electrode, the other two sides of the hollow square being at the level of the data line. Two different means for providing electrical contact between all four sides of said lower capacitor electrode are described.
A process for manufacturing the display is described.
