    Abstract: A display panel includes a plurality of display elements arranged in a display area, an opening, a multi-layer including a first layer and a second layer disposed on the first layer, and a groove. Each display element includes a pixel electrode, an emission layer disposed on the pixel electrode, and an opposite electrode disposed on the emission layer. The display area surrounds the opening. The groove is located between the opening and the display area. The groove has an undercut cross-section that is concave in a thickness direction of the multi-layer, the second layer includes a pair of tips that protrude toward a center of the groove, and a length of each tip is less than about 2 μm.

    Abstract: A display panel includes a light emitting element layer comprising a pixel definition layer having an opening defined therethrough and a light emitting element disposed in the opening. The pixel definition layer includes a first barrier portion and a second barrier portion spaced apart from each other in a first direction to define a first space having a first length in the first direction. A first inorganic layer covers the light emitting element layer. The first inorganic layer includes an uneven upper surface corresponding to the first space. An organic layer is in contact with an upper surface of the first in layer. A first groove is defined by the upper surface of the first inorganic layer overlapping the first space. A thickness of the first inorganic layer overlapping the fist space varies. The organic layer is filled in the first groove.

    Abstract: The present disclosure provides a display device with a display panel, an input sensing unit, and a protective member. The input sensing unit is disposed on the display panel. The protective member includes an insulating material and is disposed on the input sensing unit. The protective member includes a first protective portion and a second protective portion disposed on the first protective portion, where a first modulus of the first protective portion is greater than a second modulus of the second protective portion. The second protective portion with the lower modulus absorbs external impacts, and the protective portion with the higher modulus disperses the absorbed impact and prevents the display panel from being deformed by an external force. Therefore, the impact resistance of the display device is improved.
