An electroluminescent display device according to an exemplary embodiment of the present disclosure includes a display panel divided into a display area and a non-display area, a planarization layer and a bank extended to the non-display area of the display panel, an organic layer and a cathode disposed on the bank and extended to the non-display area of the display panel, a trench which is disposed in the non-display area outside the display area and from which the cathode, the organic layer, the bank and the planarization layer are removed; an under-cut structure which is disposed within the trench and composed of the bank and the planarization layer and in which the planarization layer retreats inwards from an end of the bank to generate an under-cut and an adhesive layer and an encapsulation substrate disposed on the cathode. Thus, reliability can be improved and a bezel width can be reduced.

Electroluminescent display device

The present disclosure relates to a display device including a piezoelectric film type actuator, the display device having a structure in which a groove is provided in a rear surface of a metal layer for supporting and encapsulate a rear surface of a display panel and the piezoelectric film type actuator is disposed in the groove. Accordingly, the display device may reduce the overall thickness and improve heat dissipation performance.

Display device with piezoelectric actuator

An electroluminescent display device includes a display panel having a display area and a non-display area. A planarization layer is over the non-display area. A bank is on the planarization layer. An organic layer and a cathode are on the bank. A trench pattern extends through the cathode and the organic layer. An adhesive layer and an encapsulation substrate are disposed over the cathode. The adhesive layer covers the trench pattern. The adhesive layer is effective to slow a rate of moisture penetration to a side surface of the non-display area, allowing for improvements in reliability and a reduction in bezel width.

Discussed is a display device capable of improving heat dissipation performance. The display device includes a display panel, and a back cover to support the display panel, wherein the back cover includes a first back cover stacked on the display panel and a second back cover stacked on the first back cover, where the back cover has thermal conductivity.

Display device

A display device may prevent signal lines in a non-display area from being damaged by particles. The display device may include a first substrate including a display area and a non-display area, a first electrode in the display area over the first substrate, a light emitting layer over the first electrode, a second electrode over the light emitting layer, lines in the non-display area over the first substrate, organic patterns over the lines and spaced apart from one another, an adhesive layer over the organic patterns, and a second substrate over the adhesive layer. The light emitting layer and the second electrode are provided from the display area to the non-display area, and spaced distances among the organic patterns are shorter than a distance from an upper surface of the second electrode provided over the organic patterns to an upper surface of the adhesive layer.

An organic light emitting display device including a plurality of pixels having a first sub-pixel and a second sub-pixel comprises a base substrate; a first anode disposed on the base substrate in the first sub-pixel; a second anode disposed on the base substrate in the second sub-pixel; an anode connection part connected to the first and second anodes; a driving transistor including a drain electrode that contacts the anode connection part and switching a driving power supplied to the first and second anodes; an organic light emitting layer disposed on the first and second anodes; a cathode disposed on the organic light emitting layer; and a dummy repair part including a plurality of metal layers overlapping each other with an insulating film interposed therebetween in a laser irradiation area, wherein at least one metal layer among the plurality of metal layers contacts the drain electrode and the cathode has an opened shape in the laser irradiation area.

Organic light emitting display device and method for repairing organic light emitting display device

Disclosed is an organic light emitting display device including an anode, a cathode, a plurality of organic layers and a partition member. The plurality of organic layers is disposed between the anode and the cathode, where at least one layer is separated to minimize current leakage into neighboring pixels. The partition member is disposed between the neighboring pixels and configured to separate the plurality of organic layers. The least one separated layer includes a charge generation layer.
