Abstract: A position-sensitive liquid crystal display applicable to a thin input-output pad utilized for a pen-based computer is disclosed, which employs the liquid crystal display endowed with a position-sensitive function and a simple process for producing the same, exclusive of superimposing the liquid crystal display on a position-sensitive device. The position-sensitive liquid crystal display includes an upper substrate having a position-sensitive device therein, a lower substrate joined with the upper substrate and a liquid crystal injected between the upper and the lower substrates. The process for producing the same omits the step of joining the liquid crystal display with the position-sensitive device and is thus simple.

Abstract: There is disclosed an LCD element which prevents delamination of a main data line and a redundancy line caused by the stress therebetween and breaking of the data line. It comprises a partially patterned redundancy line which reinforces a data line to prevent wire-breaking of the data line. According to the reinforcement, the stress is reduced, which leads to increasing adhesion between an ITO transparent electrode and the source-drain electrode. The advantages are accomplished by patterning the main data line and the redundancy line in part, forming the ITO and the source electrode in a variety of patterns or changing the lamination order therebetween.

Abstract: A slope etching process including dipping a pattern forming layer into a predetermined dipping solution containing an etching solution or wet etching and deionized water, so as to utilize a wet etching method only for isotropic etching. There is also provided a slope etching process including forming a photoresist pattern layer having inclined edges and etching the photoresist pattern layer together with the pattern forming layer by using a gas mixture containing an etching gas for dry etching and O.sub.2 gas, so as to utilize a RIE method only for anisotropic etching. According to the processes, it is possible to slope etch the pattern forming layer so as to form a pattern layer having a desired edge slope. Furthermore, the step coverage after process integration and productivity can be improved.

Abstract: A thin film active matrix circuit for use in a TFT-LCD color television set for simplifying the signal drive unit, enlarging the effective area of a screen, and maintaining the uniformity of the picture quality by connecting source bus lines to thin film display members of pixels corresponding to one kind of color so that the pixels can be maintained in the shape of a regular tetragon.
