The light emitting display device comprises: a substrate including a plurality of pixels that are arranged in a first direction and a second direction that crosses the first direction; a first electrode for each pixel on the substrate; a pixel defining layer on the substrate, the pixel defining layer having an opening for exposing the first electrode; a hole injection layer on the first electrode; a lyophilic pattern extending on the hole injection layer to cover the first electrode and the pixel defining layer that are on a same line in the first direction, and extending up to an outer region of outermost pixels of the plurality of pixels in the first direction; a hole transport layer on the lyophilic pattern; a light emitting layer on the hole transport layer; and a second electrode on the light emitting layer, wherein the lyophilic pattern includes a first lyophilic pattern having a plurality of grooves on one end portion thereof in the first direction and a second lyophilic pattern having a plurality of grooves on another end portion thereof in the first direction, and wherein the first lyophilic pattern and the second lyophilic pattern are alternately arranged in the second direction.

Light emitting display device and method for fabricating the same

An organic light emitting diode display including: a plurality of pixel electrodes disposed on a substrate; a pixel defining layer disposed on the pixel electrodes and including a plurality of openings exposing the respective pixel electrodes; a plurality of organic emission layers disposed on the respective pixel electrodes; and intermediate pattern layers respectively disposed between the pixel electrodes and the organic emission layers. The intermediate pattern layers include a plurality of first patterns that are extended while being respectively connected along the openings neighboring along a predetermined path.

Organic light emitting diode display and manufacturing method thereof

An organic light emitting diode display includes a substrate, a display pixel unit that displays an image, the display pixel unit being on the substrate, and a dummy pixel unit near the display pixel unit on the substrate. The display pixel unit includes a first electrode on the substrate, an organic emission layer on the first electrode, and a second electrode on the organic emission layer. The dummy pixel unit includes a second electrode formed on the substrate and does not include an organic emission layer.
