Abstract A liquid crystal display in which driver ICs are directly mounted on substrates for accessing a display portion according to a COG mounting method, where the outward connecting portion of each driver IC is arranged in a direction substantially perpendicular to that of the display portion viewed from an IC mounting portion on which the driver IC is mounted, each outward connecting portion connecting input electrodes connected to the input terminals of each driver IC to each external wiring. The projecting lengths of flanges of the liquid crystal display on the substrates are shortened and consequently the outer dimensions of the liquid crystal display are reduced by more than 20%. Moreover, it is also possible to increase the yield of a multiple-display layout by more than 50% during manufacture. Furthermore, in case of manufacturing an active-matrix liquid crystal display employing anodic oxidation method, common-electrode-cutting-off portions and consequently the cutting-off process thereof can be omitted to simplify the manufacturing process.
A liquid crystal display having first and second substrates comprising: a display portion; driving electrodes which are connected to the output terminals of first and second driver ICs for accessing said display portion; IC mounting portions formed on said first and second substrates for mounting said first and second driver ICs, respectively, thereon; and first and second outward connecting portions for connecting input electrodes which are connected to input terminals of said first and second driver ICs, respectively, to external wirings; wherein a direction of said outward connecting portion of said each IC mounting portion viewed from said IC mounting portion is arranged substantially perpendicular to that of said display portion viewed from said IC mounting portion, and wherein said first and said second outward connecting portions extend separately from different locations on the first and second substrates, respectively.
