Abstract
A wiring structure, a substrate for a display device provided therewith and a display device. The display device features a high brightness and a good display quality. The display device comprises a plurality of pixel regions arranged on a glass substrate; a TFT arranged for each of the pixel regions; an organic EL element including an anode formed by using an ITO for each of the pixel regions, and electrically connected to the source electrode of the TFT, an organic EL layer formed on the anode, and a cathode formed on the organic EL layer to transmit light from the organic EL layer; and a reflection plate for reflecting light from the organic EL layer.
Claims6
A display device comprising:
- a plurality of pixel regions arranged on a substrate;
- a thin film transistor arranged for each of the pixel regions;
- an organic electroluminescence element including an anode formed by using a transparent electrically conducting material for each of the pixel regions, and electrically connected to the source electrode of the thin film transistor, an organic electroluminescence layer formed on the anode, and a cathode formed on the organic electroluminescence layer to transmit light from the organic electroluminescence layer;
- and
- a reflection plate arranged in direct contact with the anode, as well as being entirely covered by the anode on an upper surface and both side edges thereof, such that the organic electroluminescence layer does not contact the reflection plate, and wherein the reflection plate is configured to reflect light from the organic electroluminescence layer.
