Abstract: An apparatus for manufacturing a display device, includes: a stage; a temperature controlling portion on the stage, and to receive a member seated on the temperature controlling portion; and a jig portion facing the temperature controlling portion, the jig portion to move linearly, and to receive an adhesive member. The jig portion includes: a first support plate; a second support plate facing the first support plate; and a pressurization plate on the first support plate and the second support plate, the pressurization plate to receive the adhesive member thereon. An end of the pressurization plate is spaced further from the member than an end of the first support plate and an end of the second support plate when the member is seated on the temperature controlling portion.
