A display may have an array of pixels formed from organic light-emitting diodes and thin-film transistor circuitry. Each pixel may include organic layers interposed between an anode and a cathode. The organic layers may emit out-coupled light that escapes the display and waveguided light that is waveguided within the organic layers. A reflector may be placed at the edge of the organic layers to reflect the waveguided light out of the display. The reflector may be located within a pixel definition layer and may be formed from metal or may be formed from one or more interfaces between high-refractive-index material and low-refractive-index material. The reflector may be formed from an extended portion of the pixel anode. The reflector may be formed from light-reflecting particles that are suspended in the pixel definition layer.

Organic light-emitting diode displays with reflectors

An organic electroluminescence display panel that includes a plurality of first pixel areas, a plurality of second pixel areas, and a plurality of third pixel areas is provided. The organic electroluminescence display panel includes a first electrode layer, an organic layer including a light-emitting layer made of organic light-emitting material and a second electrode layer. The first electrode layer includes a reflective material. The organic layer is located on the first electrode layer. The second electrode layer is located on the organic layer. The material of the second electrode layer includes a transparent metal oxide conductive material. The thickness of the second electrode layer is a single thickness and is greater than 300 nm.
