Organic light-emitting diode (OLED) display

摘要

An organic light-emitting diode (OLED) display is disclosed. In one aspect, the OLED display includes a thin film transistor including an active layer, a gate electrode, a source electrode, and a drain electrode, a first insulating layer arranged between the active layer and the gate electrode, and a second insulating layer arranged between the gate, source, and drain electrodes. The OLED display also includes a third insulating layer covering the source and drain electrodes, wherein an opening is defined in each of the second and third insulating layers and wherein the openings substantially overlap. The OLED display further includes a pixel electrode formed in the openings defined in the second and third insulating layers and including a semi-permeable metal layer.
