Abstract: A printing pad includes a bottom surface extending in a plane defined in a first direction and a second direction intersecting the first direction. A first upper surface faces the bottom surface. A first side surface connects the bottom surface and the first upper surface. A second portion is disposed on the first portion and includes a second upper surface facing the first upper surface and a second side surface connecting the first upper surface and the second upper surface. A width of the second portion in the first direction increases from the first upper surface towards the second upper surface.

Abstract: A display panel is disclosed that includes a base layer including a first pixel area and a second pixel area adjacent to the first pixel area, a pixel definition layer disposed on the base layer and provided with a pixel opening defined therethrough to correspond to each of the first pixel area and the second pixel area, and a first electrode of which at least a portion is disposed in the pixel opening. The pixel definition layer includes a first slant portion, a second slant portion spaced apart from the first slant portion, a first convex portion disposed between the first slant portion and the second slant portion and adjacent to the first slant portion, and a first flat portion disposed between the first slant portion and the second slant portion and adjacent to the second slant portion.
