JA9-91-044 LIQUID CRYSTAL DISPLAY DEVICE ABSTRACT A liquid crystal display device includes a first transparent insulating substrate having a common electrode. A second transparent insulating substrate has gate lines formed in one direction and intersecting data lines in the other direction. Liquid crystal display cells are formed at each cross-point of the gate and data lines and include thin film transistors and display electrodes; a light shielding layer includes an aperture for exposing a display area of each display electrode and liquid crystal material retained between the first and second substrates. The device is characterized in that the light shielding layer of edge of the aperture located at the upper stream of a rubbing direction comprises a thin light shielding layer formed at the periphery of the display electrode for defining edge of the aperture and, a thick light shielding layerhaving an edge positioned on the thin light shielding layer. The present invention improves the quality of a displayed image of a liquid crystal display device which has been degraded by a reverse tilt.
