Abstract
Pixels of a display device include a first substrate, an organic insulation layer disposed on the first substrate and having an upper surface formed in an uneven structure, an inorganic insulation layer disposed on the organic insulation layer and formed in the uneven structure, a first electrode disposed on the inorganic insulation layer and formed in the uneven structure, and a device to provide a data voltage to the first electrode, in which the first electrode includes a reflective electrode to reflect incident light.
Claims13
A method of fabricating a display device comprising a plurality of pixels, the method comprising:
- forming an organic insulation layer on a first substrate;
- stressing the organic insulation layer via deposition of an inorganic insulation layer on the organic insulation layer, stress of the deposition causing, at least in part, an uneven structure in an upper surface of the organic insulation layer, the inorganic insulation layer being formed with the uneven structure in an upper surface of the inorganic insulation layer;
- and
- forming a first electrode on the inorganic insulation layer, an upper surface of the first electrode being formed with the uneven structure,
- wherein the forming of the first electrode comprises forming a reflective electrode.
A method of fabricating a display device comprising a plurality of pixels, the method comprising:
- forming an organic insulation layer on a first substrate;
- stressing the organic insulation layer via deposition of an inorganic insulation layer on the organic insulation layer, stress of the deposition causing, at least in part, a roughing of an upper surface of the organic insulation layer;
- and
- forming a conductive material on the inorganic insulation layer,
- wherein an upper surface of the conductive material and an upper surface of the inorganic insulation layer have a roughened upper surface that corresponds to the roughened upper surface of the organic insulation layer, and
- wherein a root mean square roughness value of the roughened upper surface of the organic insulation layer is in a range of about 10 nm to about 200 nm.
