Patent ID: 8908117

Claim:
A thin film transistor (TFT) array substrate having an array area, in which thin film transistors are arranged in an array shape, and a frame area, which is provided to surround the array area, the thin film transistor array substrate comprising: a thin film transistor includes: a substrate; a gate electrode formed on the substrate; a gate insulation film that covers the substrate and also covers the gate electrode; a semiconductor layer formed on the gate insulation film above the gate electrode; and a source electrode and a drain electrode formed above the semiconductor layer with sandwiching an ohmic contact film; an electrode pattern configured by the source electrode and the drain electrode; an upper metal pattern formed by the same material as the source and drain electrodes at the same layer; a transparent conductive film pattern formed to directly overlap with at least one of the electrode pattern and the upper metal pattern; and an upper layer insulation film that covers the gate insulation film and also covers the transparent conductive film pattern, wherein the transparent conductive film pattern has: a first-type transparent conductive film pattern that is provided to be located within one of a pattern of the electrode pattern and a pattern of the upper metal pattern, as viewed from the top side, wherein a first-type transparent conductive film pattern is formed to not cover pattern end faces of the electrode pattern or the upper metal pattern; and a second-type transparent conductive film pattern that is provided to stick out from an inside of at least a portion of one of the electrode pattern and the upper metal pattern, as viewed from the top side, wherein the second-type transparent conductive film pattern is stuck out to cover the pattern end faces of the electrode pattern or the upper metal pattern, and wherein the transparent conductive film pattern formed at least in the frame area is configured by the first-type transparent conductive film pattern formed to not cover the pattern end faces of the electrode pattern or the upper metal pattern.
