Abstract: An apparatus and system for bonding substrates are presented. The apparatus includes a base member formed of an insulating material and an electric field generation part formed of a conductive material. The electric field generation part extends into the base member. The electric field generation part includes a trunk part and a branch part. The trunk part extends in a first direction. The branch part extends from the trunk part in a direction different from the first direction. A substrate is fixed on the base member. An adhesive is applied on the substrate in a shape that matches that of the electric field generation part. An electric field is generated using the electric field generation part and the substrate is bonded to another substrate. The apparatus prevents or reduces formation of air bubbles in the adhesive. A method of manufacturing a display device is also presented.

Abstract: An organic light emitting diode display includes a display panel including a display area to which a touch screen panel is attached and a pad area in which a metal wire is formed; a cover window on one side of the display panel; a resin layer between the display panel and the cover window; and a touch screen circuit film in the pad area and connected to the touch screen panel, at least one of the touch screen circuit film and the metal wire including an ultraviolet ray transmitter configured to increase a hardening degree of the resin layer in the pad area.

Abstract: A method of manufacturing a flexible display device includes a first step of providing a three-dimensional cover window having a flat portion, and a curved portion that is bent in a third direction intersecting a first direction of the flat portion while extending to a second direction intersecting the first direction at both sides of the first direction, and a second step of attaching by a line contact at least one of an adhesive film, a touch panel, and a flexible display panel that are stacked at an inner surface of the cover window.

Abstract: An organic light emitting diode (OLED) display device includes a display panel that has a plurality of signal lines and a plurality of pixels to display an image, a cover window that is positioned at the outside of a display surface of the display panel, and an adhesive layer that is positioned between the display surface and the cover window. One of the display panel and the cover window forms a concave channel in at least one corner, and the adhesive layer fills the channel.
