Abstract: An organic light-emitting diode display device can include a substrate including sub-pixels associated with one pixel, each sub-pixel having an emission area and a non-emission area; first conductive lines and a second conductive line over the substrate, wherein the second conductive line crosses over the first conductive lines to define the sub-pixels; a circuit portion in the non-emission area of each sub-pixel, and including a thin film transistor in each sub-pixel; an overcoat layer over the thin film transistors and including micro lenses in the emission area of each sub-pixel; and a light-emitting diode in the emission area of each sub-pixel over the overcoat layer, and connected to the corresponding thin film transistor. For a first sub-pixel among the sub-pixels, the overcoat layer can have a depressed pattern corresponding to the non-emission area of the first sub-pixel and overlapping one of the first conductive lines.

Abstract: An organic light-emitting diode display device can include a plurality of sub-pixels disposed over a substrate where each sub-pixel has an emission area and a non-emission area, a thin film transistor in the non-emission area of each sub-pixel, and an overcoat layer over the thin film transistor in each sub-pixel and including a plurality of micro lenses in the emission area of each sub-pixel. The organic light-emitting diode display device can further include a light-emitting diode in the emission area of each sub-pixel over the overcoat layer and connected to the corresponding thin film transistor. For one sub-pixel among the plurality of sub-pixels, the emission area of the one sub-pixel has at least one flat portion disposed at the overcoat layer where a top surface of the overcoat layer is flat, and the overcoat layer has at least one lens pattern in the at least one flat portion.
