1. A printing pad comprising:
a first portion including a bottom surface extending in a plane defined in a first direction and a second direction intersecting the first direction, a first upper surface facing the bottom surface, and a first side surface connecting the bottom surface and the first upper surface; and
a second portion disposed on the first portion and including a second upper surface facing the first upper surface and a second side surface connecting the first upper surface and the second upper surface,
wherein a first material included in the first portion and a second material included in the second portion are different from each other,
wherein a width of the second portion in the first direction increases from the first upper surface towards the second upper surface,
wherein an angle of the second side surface with respect to a third direction perpendicular to the bottom surface from a lower portion of the second side surface proximate to the first upper surface to an upper portion of the second side surface proximate to the second upper surface is in a range of about 10° to about 12°,
wherein an upper portion of the first side surface directly contacting the second side surface is inwardly curved and the upper portion of the first side surface and the second side surface together form a concave shape, wherein the second side surface extends linearly in the range of about 10° to about 12° from the concave shape to the upper portion of the second side surface proximate to the second upper surface, and
wherein the upper portion of the second side surface proximate to the upper surface is rounded and directly contacts the linearly extending second side surface.
