Abstract
An organic light emitting diode display includes a substrate main body, a semiconductor layer and a first capacitor electrode on the substrate main body, bottom surfaces of the semiconductor layer and first capacitor electrode being substantially coplanar, and each of the semiconductor layer and first capacitor electrode including an impurity-doped polysilicon layer, a gate insulating layer on the semiconductor layer and the first capacitor electrode, a gate electrode on the semiconductor layer with the gate insulating layer therebetween, and a second capacitor electrode on the first capacitor electrode with the gate insulating layer therebetween, the second capacitor electrode including a convex electrode portion and a concave electrode portion, the concave electrode portion being thinner than each of the convex electrode portion and the gate electrode.
