Abstract:
1. An organic electroluminescence display device comprising a plurality of unit pixels disposed in a matrix on a substrate, wherein each of the unit pixels has a thin film transistor including a channel region, the thin film transistor formed at a position other than a center of the unit pixel, the unit pixel including an irradiated area that has been irradiated with laser light while the thin film transistor is formed to crystallize at least said channel region, wherein unit pixels in a first row and unit pixels in a second row adjacent to the first row are arranged symmetrically with respect to a first virtual plane orthogonal to a main surface of the substrate, wherein each of the unit pixels further comprises a gate wiring made of a first material whose thermal resistance is lower than the thermal resistance of a gate electrode of the thin film transistor, wherein each of the gate wiring includes a first portion extending in a row direction of the unit pixels and a second portion extending from the first portion towards the respective thin film transistors, wherein the second portion of the gate wiring made of the first material is electrically connected to the gate electrode made of at least a second material different than the first material, wherein each of said gate wiring is arranged at a position further away from the first virtual plane than the thin film transistor, and wherein the irradiated area of the unit pixel includes an area encompassing the thin film transistor, but excludes an area encompassing the first portion of the gate wiring and at least a part of the second portion of the gate wiring.
