Patent ID: 7928653

Claim:
An organic light emitting diode (OLED) display, comprising: a substrate; a thin film transistor on a transistor region of the substrate, the thin film transistor including a semiconductor layer, a gate electrode, a source electrode and a drain electrode; a scan line in a same layer as the gate electrode that is in a metal line region of the substrate; a common power supply line and a data line in the same layer as the source electrode and the drain electrode; a first electrode overlapping the scan line, the common power supply line, and/or the data line, the first electrode being transparent; a pixel defining layer defining an opening portion, the pixel defining layer on the first electrode; an organic layer on a portion of the first electrode and comprising at least an organic emission layer; and a second electrode on the organic layer, wherein a width between parallel and facing edges of the opening portion is equal to a distance between facing edges of the common power supply line and the data line.
