ABSTRACT:
The present invention relates to a light emitting device where difference of brightness of pixels can be reduced when the same data currents are applied to the pixels. The light emitting device includes anode electrode layers, cathode electrode layers, pixels and cathode lines. The anode electrode layers are disposed in a first direction. The cathode electrode layers are disposed in a second direction. The pixels are formed in cross areas of the anode electrode layers and the cathode electrode layers. The cathode lines are coupled to the cathode electrode layers. Here, in one cathode electrode layer, at least one of resistors between parts corresponding to pixels except a first pixel next to a cathode line corresponding to the cathode electrode layer has resistance smaller than resistor between a part corresponding to the first pixel and a part corresponding to a pixel next to the first pixel.
