LIQUID CRYSTAL APPARATUS, ITS MANUFACTURE AND PROJECTION DISPLAY

摘要

The four corners of a generally rectangular sealing member (11) which is provided between a device substrate (10) and a facing substrate (20) are triangularly cut and removed to form cut parts (11b). Through-conductors (13) with which signal input pads (18) formed on the device substrate are electrically connected to transparent electrodes (22) formed on the facing substrate are formed in the generally triangular regions which are defined by the cut parts (11b). The through-conductors are substantially uniformly distributed along the outer periphery of the sealing member. The through-conductors function as supporting columns for joining the device substrate and the facing substrate to each other. Even if the facing substrate is pressed against the sealing member partially when both the substrates are joined to each other, the deformation of the sealing member is suppressed. As a result, the harmful influence upon the sealing ability of the sealing member in a liquid crystal apparatus can be avoided and, further, a uniform cell thickness can be obtained.
