Abstract: Provided is a method of manufacturing an organic light-emitting display apparatus which may reduce white angular dependency (WAD). The method includes forming a common layer on each of subpixel areas at the same time without discretion within one pixel area, the common layer not being formed on connection areas between pixel areas.

Abstract: An organic light emitting diode (OLED) display device and a method of fabricating the same are provided. The OLED display device includes a substrate having a thin film transistor region and a capacitor region, a buffer layer disposed on the substrate, a gate insulating layer disposed on the substrate, a lower capacitor electrode disposed on the gate insulating layer in the capacitor region, an interlayer insulating layer disposed on the substrate, and an upper capacitor electrode disposed on the interlayer insulating layer and facing the lower capacitor electrode, wherein regions of each of the buffer layer, the gate insulating layer, the interlayer insulating layer, the lower capacitor electrode, and the upper capacitor electrode have surfaces in which protrusions having the same shape as grain boundaries of the semiconductor layer are formed. The resultant capacitor has an increased surface area, and therefore, an increased capacitance.
