A display panel includes a base layer including a display area and a non-display area adjacent to the display area, a plurality of light-emitting elements disposed in the display area, a hydrophobic layer disposed in the non-display area and spaced apart from the light-emitting elements, an insulating layer disposed on the light-emitting elements and including an upper surface and an inclined surface inclined with respect to the upper surface, and a plurality of patterns contacting with the hydrophobic layer, and the plurality of patterns is spaced apart from the inclined surface.

Display panel and electronic device including the same

A display device includes: a display panel including a base layer, a light emitting element layer, and an encapsulation layer; and an input detection unit disposed on the display panel, wherein the display panel includes: a first side and a second side, wherein the encapsulation layer includes an organic encapsulation layer including: an inclined part adjacent to the first side and the second side; and a flat part extending from the inclined part, wherein a first angle formed by the inclined part with respect to an upper surface of the base layer in a first part of the display panel and input detection unit adjacent to the first side is less than a second angle formed by the inclined part with respect to the upper surface of the base layer in a second part of the display panel and input detection unit adjacent to the second side.

Display device and manufacturing method of the same

An inkjet printing apparatus includes: a stage, which reciprocates in forward and reverse directions opposite to each other and has a target substrate disposed thereon; an inspection device including a film disposed outside the stage and a measurement unit which measures an inspection pattern provided on the film; and a head assembly, which moves along one direction crossing the forward direction and has a plurality of heads which supplies a liquid composition to the target substrate. The head assembly moves in the one direction to overlap the film and sprays the composition onto the film to form an inspection pattern.
