Abstract

An organic light-emitting diode display device includes a first light-emitting layer, a first anode, a first reflective pattern, and a dielectric material. The first light-emitting layer, the first anode, and the first reflective pattern are located in a first sub-pixel region. The first anode is disposed under the first light-emitting layer in a vertical direction, and the first reflective pattern is disposed under the first anode in the vertical direction. The dielectric material is partly disposed between the first anode and the first reflective pattern, and the first reflective pattern is electrically connected with the first anode.
