Abstract
The present disclosure provides an organic light-emitting display apparatus and a fabrication method thereof. The organic light-emitting display apparatus comprises a substrate having a device component layer; first electrodes disposed over the device component layer; a pixel-defining layer having opening regions to expose the first electrodes formed over the device component layer; photo spacers, disposed on the pixel-defining layer, and surrounding at least one opening region to provide a first photo spacer group along the at least one opening region in a first direction and provide a second photo spacer group along the at least one opening region in a second direction; an organic light-emitting layer disposed in the opening regions of the pixel-defining layer and in contact with the first electrodes; and a second electrode disposed on the light-emitting layer. The first photo spacer group has a continuous projection on the first direction, and the second photo spacer group has a continuous projection on the second direction.
