Abstract: An apparatus for manufacturing a display device includes a stage to support first and second members, and a pressurization portion spaced apart from the stage and to press the first or second member. The pressurization portion includes: a contact portion facing the stage and to contact the first or second member; a first force application unit connected to the contact portion and to linearly move the contact portion; and a second force application unit connected to the contact portion and spaced apart from the first force application unit. The second force application unit linearly moves the contact portion in a portion of the contact portion that is different from the portion contacted by the first force application unit. At least one of the first and second force application units is configured to operate according to a force applied by the contact portion to one of the first and second members.

Abstract: An illumination apparatus includes a main light source, a half minor, and a diffusion plate. The main light source emits main light. The half mirror is spaced apart from the main light source. The half mirror reflects a first light travelling in a first direction among the main light source. The half mirror has a reflective surface reflecting the first light to travel in a second direction. The diffusion plate is disposed between the main light source and the half mirror not overlapping the reflective surface. The diffusion plate has a first horizontal surface and a second horizontal surface. The second horizontal surface is a rear surface of the first horizontal surface. The diffusion plate transmits a second light incident on the first horizontal surface among the main light. The diffusion plate scatters the second light from the second horizontal surface.
