Patent ID: 7633090

Claim:
A thin film transistor panel, comprising: a transparent substrate; scanning lines made of a transparent electroconductive material, formed on the transparent substrate; data lines made of a transparent electroconductive material, formed on the transparent substrate to be perpendicular to the scanning lines; thin film transistors, each including a transparent gate electrode connected to one of the scanning lines, a transparent drain electrode connected to one of the data lines, a transparent source electrode, and a transparent semiconductor thin film made of a metal oxide and including a channel region at a middle portion thereof; transparent pixel electrodes connected to the thin film transistors; and a light blocking film formed between the transparent pixel electrodes and having a width wider than gaps between the transparent pixel electrodes so as to overlap with peripheral portions of the transparent pixel electrodes in a plan view, the light blocking film being formed continuously all the way along the scanning lines and the data lines without any break; wherein the scanning lines and the data lines extend substantially all the way along the gaps between the transparent pixel electrodes; and wherein each of the transparent pixel electrodes is formed to cover a respective one of the thin film transistors, and the light blocking film is formed so as not to overlap with the channel regions of the transparent semiconductor thin films of the thin film transistors.
