Three-dimensional (3D) light-emitting diode display device

The present invention relates to a 3D light emitting diode display device, comprising a transparent substrate, an anode, a light emitting structure layer, phase retardation film and a cathode. Wherein the cathode is disposed on the light emitting structure layer, and the cathode in contact with a surface of the light emitting structure layer having a plurality of first regions and a plurality of second regions. The plurality of first regions and the plurality of second width corresponding to the width of each region of the sub-pixel units. The plurality of first regions having a first plurality of parallel micro-grooves, the plurality of second regions having a second plurality of parallel micro channel, and the first region and the second region are arranged in parallel spaced. 3D light emitting diode display device of the present invention are omitted polarizer element means generally required 3D light emitting diode display, and simplifies the process.
