Patent Images
1. An organic light emitting diode display, comprising:
- a substrate;
a control electrode disposed on the substrate;
a gate insulating film covering the control electrode the gate insulating film having an opening that exposes the substrate;
an input electrode and an output electrode disposed on the gate insulating film and facing each other;
an oxide semiconductor disposed on the input electrode and the output electrode and disposed over the control electrode;
a pixel electrode disposed on and electrically connected to portions of edges of the output electrode;
an organic light emitting member disposed on the pixel electrode;
a common electrode disposed on the organic light emitting member, anda blocking member covering the opening that exposes the substrate and configured such that light entering lower portions or lateral sides of the oxide semiconductor is blocked,wherein the pixel electrode comprises the same material as the oxide semiconductor.

Abstract
An organic light emitting diode display includes a substrate. A control electrode is on the substrate. A gate insulating film covers the control electrode. An input electrode and an output electrode are on the gate insulating film and face each other. An oxide semiconductor is between the input electrode and the output electrode and on the control electrode. A pixel electrode is on portions of the edges of the output electrode and is electrically connected. An organic light emitting member is on the pixel electrode. A common electrode is on the organic light emitting member. The oxide semiconductor and the pixel electrode may be of the same layer.
