Abstract:
1. An organic light emitting diode display comprising: a substrate; a gate line formed on the substrate; a data line formed to intersect with the gate line; a driving voltage line including a portion parallel to at least one of the gate line and the data line; a light blocking member formed under the gate line, the data line, and the driving voltage line, and the gate line, the data line and the driving voltage line substantially overlapping the light blocking member, wherein the light blocking member has substantially a same shape as portions of the gate line, the data line, and the driving voltage line aligned with the light blocking member; a switching thin film transistor connected to the gate line and the data line and including an amorphous semiconductor; a driving thin film transistor connected to the switching thin film transistor and including a crystalline semiconductor; and
