Patent ID: 7795621

Claim:
A thin film transistor panel comprising: a transparent substrate; scanning lines which are made of a light blocking electroconductive material, and which are formed on the transparent substrate; data lines which are formed on the transparent substrate perpendicular to the scanning lines, and which are made of the light blocking electroconductive material; thin film transistors each including: (i) a transparent gate electrode, a part of which overlaps one of the scanning lines so as to be electrically connected to the one of the scanning lines, (ii) a transparent drain electrode, a part of which overlaps one of the data lines so as to be electrically connected to the one of the data lines, (iii) a transparent source electrode, and (iv) a transparent metal oxide semiconductor thin film; transparent pixel electrodes which are formed with a transparent metal oxide as anode electrodes, and which are electrically connected to the source electrode; and an organic EL layer and a cathode electrode which are formed in a region corresponding to each of the anode electrodes, wherein each of the pixel electrodes covers at least a part of the gate electrode so as to avoid a region where the gate electrode overlaps the one of the scanning lines, and the pixel electrodes also function as the source electrodes.
