Substrate for use in a liquid crystal display and liquid crystal display using the same

Abstract

The invention relates to a substrate for use in a liquid crystal display of a CF-on-TFT structure in which a color filter is formed on the side of an array substrate in which a switching element is formed, and has an object to provide a substrate for use in a liquid crystal display, which enables simplification of a manufacturing process typified by a photolithography process and has high reliability. The substrate for use in the liquid crystal display is constructed to include external connection terminals which include first terminal electrodes electrically connected to gate bus lines led out from a plurality of pixel regions arranged on a glass substrate in a matrix form, second terminal electrodes formed of forming material of a pixel electrode and directly on the glass substrate, and electrode coupling regions for electrically connecting the first and the second terminal electrodes, and which electrically connect an external circuit and the gate bus lines.

AI Technical Summary

Benefits of technology

This approach enhances the manufacturing process reliability, reduces light leakage, prevents contamination, and maintains uniform cell thickness, achieving high light shielding capability and improved display quality.

Problems solved by technology

When a resin layer is formed on the whole surface of the substrate, and an electrode wiring line made of, for example, a transparent oxide electrode material or the like is formed on the resin layer, the adhesion of the wiring line or the like to the resin layer is often inferior to that to a glass substrate, and there is a case where peeling occurs.

In the CF-on-TFT structure in which the opposite electrode does not have a light shielding film, an intense light leakage from a backlight unit is problematic in the frame region of the periphery of a display region.
