A display device includes a substrate including a display region and a peripheral region, display structures at the display region of the substrate, a plurality of blocking structures at the peripheral region of the substrate wherein the blocking structures have heights different from each other, an organic layer on the display structures and the blocking structures, and an inorganic layer on the organic layer.

Display devices and methods of manufacturing display devices

An organic light-emitting display apparatus includes: a first substrate; an insulating layer on the first substrate; a signal wiring on the insulating layer; an organic light-emitting device on the first substrate, the organic light-emitting device defining an active area and including a first electrode, a second electrode, and an intermediate layer between the first and second electrodes; a passivation layer on the insulating layer; and a metal layer on the passivation layer at an outer region adjacent to the active area, separated from the first electrode, and contacting the second electrode and the signal wiring, wherein a first opening is in the passivation layer at the outer region, and the metal layer contacts the insulating layer at the first opening.

Organic light-emitting display apparatus

A display apparatus includes a substrate on which a central area and a peripheral area adjacent to the central area are arranged. The central area includes a display area. The display apparatus further includes: at least one insulation pattern that is formed in the peripheral area; a groove from which a material for forming the insulation pattern is removed and that is formed adjacent to the insulation pattern; and at least one insulating layer that is interposed between the insulation pattern and the substrate. The groove is located in the at least one insulating layer.

Display apparatus and method of manufacturing the same

A thin film transistor includes a gate electrode extending from a scan line of a display and having an edge, and a connection line connecting the edge of the gate electrode to the scan line.

Thin film transistor and organic light emitting diode display

A test device for a display panel and a method of testing the same are provided. The test device for a display panel includes a luminance measurement unit that measures a luminance value of a display panel including a plurality of pixels, and a controller that determines a voltage value of a data signal corresponding to a target luminance value, receives a measured luminance value of a pixel to which the data signal is supplied from the luminance measurement unit from among the plurality of pixels, compares the measured luminance value and the target luminance value, and outputs a control signal that changes a first power source voltage value supplied from a power source voltage supply unit to the pixel until the measured luminance value does not coincide with the target luminance value.
