A display device includes a substrate including an emission area and a non-emission area and in which a plurality of sub-pixels are defined, first electrodes disposed in the plurality of sub-pixels, respectively, a bank that is disposed in the non-emission area between the plurality of sub-pixels, and exposes the first electrode through an opening, a protrusion disposed in a second non-emission area of the non-emission area which is divided into a first non-emission area at a flat top surface of the bank and the second non-emission area at an inclined top surface of the bank, an organic layer disposed on the first electrodes, and a second electrode disposed on the organic layer.

Display device with protrusion on inclined side of bank

Provided is a display device. The display device includes a base layer including an active area partitioned to display images and an inactive area adjacent to the active area, an opening located in a part of the active area and passing through the base layer and functional layers thereabove, and a cut structure located in the vicinity of the opening and provided to cut the connection of an organic light emitting layer between the opening and a light emitting unit. A camera may be provided in a position corresponding to the opening.

Display device

A display apparatus includes a substrate on which a plurality of sub-pixels is defined, a plurality of anodes disposed in each of the plurality of sub-pixels on the substrate, an organic layer disposed on the plurality of anodes, a cathode disposed on the organic layer, and a bank disposed between the anode and the organic layer and between emission areas of each of the plurality of sub-pixels. The bank includes a plurality of trenches, and the organic layer and the cathode are disposed in the bank and the plurality of trenches. As a result, a resistance of the organic layer in which a leakage current flows from the trench increases, so that the leakage current which may be transmitted to the adjacent sub-pixels and color mixing due to the leakage current can be minimized.

Display apparatus

A display device in one embodiment includes a flexible substrate, a back plate disposed under the flexible substrate to support it, a conductive layer disposed on at least one surface of the back plate, and a printed circuit board connected to one side of the flexible substrate. The conductive layer is electrically connected to the printed circuit board and receives a constant voltage applied thereto. Therefore, by applying the constant voltage to the conductive layer, it is possible to reduce the polarization occurring on the flexible substrate.
