Abstract: A display device includes a display part including a first non-folding area, a second non-folding area, and a folding area between the first non-folding area and the second non-folding area, the folding area being foldable with respect to a folding axis, a window disposed on the display part, and an adhesive layer disposed between the display part and the window, the adhesive layer including a first adhesive material and a second adhesive material having an elongation rate greater than an elongation rate of the first adhesive material. The first adhesive material has a planar area greater than a planar area of the second adhesive material in each of the first non-folding area and the second non-folding area, and the second adhesive material has a planar area greater than a planar area of the first adhesive material in the folding area.

Abstract: An inkjet print apparatus includes a stage; an inkjet head located over an upper portion of the stage, configured to move in a first direction and a second direction opposite to the first direction, and configured to eject an ink toward the stage; a first ultraviolet irradiator located behind the inkjet head with respect to the first direction first covers located at respective sides of the first ultraviolet irradiator in the first direction; a second ultraviolet irradiator located behind the inkjet head with respect to the second direction; and second covers located at respective sides of the second ultraviolet irradiator in the second direction. Further, a process for forming an adhesive layer may be simplified by using an inkjet printing method.

Abstract: A display device includes: a display panel including a display region and a non-display region; a window member on the display panel; and an adhesive member between the display panel and the window member. The adhesive member includes: a first adhesion portion overlapping the display region, and a second adhesion portion extending from the first adhesion portion and overlapping the non-display region. The display panel includes: a substrate, a display element layer on the substrate and overlapping the display region, a driving chip on the substrate and overlapping the non-display region, and an encapsulation member on the display element layer. The driving chip is configured to provide a driving signal to the display element layer. The first adhesion portion connects the window member to the encapsulation member. The second adhesion portion connects the window member to the substrate and encloses the driving chip, but does not overlap the driving chip.
