Abstract

PURPOSE:To form a black matrix to obtain the display of high visual recogniza bility by setting a liquid crystal other than a liquid crystal layer, which is interposed between upper and lower matrix electrodes, to the homeotropic orientation or hybrid orientation state and arranging a polarizer and an analyzer in the cross Nicol state. CONSTITUTION:High polymer materials for oriented film are applied on a glass substrate 2 having patterned transparent electrodes 3, 8, and 9, and an oriented layer 4 is formed by rubbing. A chromium mask on which patterned transparent electrodes are formed is arranged in the same position on the glass substrate 2, and ultraviolet rays are irradiated. By this operation, parts of the oriented film other than transparent electrodes lose the liquid crystal orienting capability. Substrates subjected to this processing are allowed to face each other and are adhered to each other with a uniform gap between them and the liquid crystal is enclosed between them, thus obtaining a TN type liquid crystal display device. If a polarizer 1 and an analyzer 6 are arranged on and under this liquid crystal display device in the cross Nicol state, parts other than display dot parts are in a black grating state 7 to obtain the display of high visual recognizability.

う問題があった。Conventionally, the X-Y matrix quasi-liquid crystal display It has produced a display by sandwiching a uniformly oriented liquid crystal layer between a polarizer and an analyzer, and applying voltage to arbitrary dots in the upper and lower matrices. However, as the display capacity has increased, the density has increased, the dots have become smaller, and the dot spacing has become narrower. Therefore, attempts have been made to increase the visibility of each dot by making the dots other than the display dots black.Generally, this has been dealt with by printing black or dyeing between the dots. □ [Problem to be solved by the invention] However, since the gag is several tens of microns,
There was a problem that printing was extremely difficult and required too many man-hours.

This is a liquid crystal display device whose main feature is to form a black matrix by arranging the elements.
