IPC: G02F1/1339
Filed: 1994-07-15
Abstract: PURPOSE:To prevent electrostatic defects in a panel without increasing the number of production processes by using a resin having conductivity for a sealing resin material to give a certain resistance to between the whole transparent electrode patterns of the panel. CONSTITUTION:A liquid crystal material is injected between glass substrates 6, 6 and the edge part of the glass substrates 6, 6 is sealed with a sealing resin material 13 comprising a thermosetting epoxy resign. The sealing resin material 13 is a resin having conductivity of 1X10<7>OMEGA.cm to 1X10<9>OMEGA.cm volume specific resistance. By this method, each line of the transparent electrode pattern in the panel is connected through the resistance component so that charges move not only into the charged transparent electrode pattern 7 but another part and sudden accumulation (discharge) of charges can be relaxed. Even when an electrostatic defect is once caused, the panel discharges by itself to other transparent electrode pattern 7, and thereby extinguishing electrostatic defects completely by only leaving the panel for a several hours.
