LIQUID CRYSTAL DISPLAY UNIT AND FORMATION OF ELECTRODE PROJECTION

Japanese Patent JPH05142555

A

PURPOSE:To assure connection with a smaller number of processes by forming projections on the electrode surfaces of a flexible substrate or a tab for driving and applying an adhesive on the electrode surfaces to be connected, thereby joining the projections to the transparent electrodes of a liquid crystal panel substrate. CONSTITUTION:The plural projections 15 are formed in the positions corresponding to the plating layer of the electrodes 12 on the flexible substrate 11 surface by pressing with a press mold. The adhesive substrate 16 is thereafter applied by means, such as printing, on the electrode terminal surface of the flexible substrate 11 formed with the projections 15. The projections 15 are formed on the electrode 12 surfaces in such a manner and further the juncture of the flexible substrate 11 coated with the adhesive 16 and the electrode terminals of the transparent electrodes of the liquid crystal panel substrate are thermcompression bonded. Then, the electrical connection of the projections 15 formed on the electrodes 12 of the flexible substrate 11 with the electrode terminals of the transparent electrodes is then obtd. while expelling the adhesive 16 thinly covering then surfaces of the projections 15 when the projections are brought into pressurized contact with the electrode terminals of the transparent electrodes of the liquid crystal panel substrate. The physical connection of both electrodes is also obtd. by curing of the adhesive material 16.
