Abstract: A mask repairing apparatus may include a stage, a stereoscopic imaging unit to measure a stereoscopic image of a mask on the stage, a control unit to compare the stereoscopic image with a normal image of the mask and to produce a defect image of the mask, and a laser unit to irradiate a laser beam onto a deficient part of the mask, under control of the control unit. The control unit may control the laser unit, based on the defect image, such that the laser beam is sequentially irradiated onto m multiple layers of the deficient part while repeatedly moving in a first direction and a second direction crossing each other.

Abstract: A display apparatus includes: a substrate; a 1-1 light-emitting device and a 1-2 light-emitting device over the substrate and each comprising a first emission layer and a first charge generation layer; a second light-emitting device adjacent to the 1-1 light-emitting device and comprising a second emission layer comprising a material that emits light of a color different from that of the first emission layer and a second charge generation layer spaced apart from the first charge generation layer; and a pixel-defining layer comprising an opening exposing a center portion of a pixel electrode of each of the 1-1 light-emitting device, the 1-2 light-emitting device, and the second light-emitting device, wherein an upper surface of the pixel-defining layer between the 1-1 light-emitting device and the 1-2 light-emitting device comprises a first groove concave toward the substrate, wherein the first charge generation layer is cut off at the first groove.
