A display apparatus can include a substrate having a penetrating area and a separating area, the penetrating area including a substrate hole, a first buffer layer having a first-buffer lower layer, and a first-buffer upper layer, a first thin film transistor including a first semiconductor pattern, a first gate electrode, and a first source electrode and a first drain electrode, a first interlayer insulating film; a second interlayer insulating film, an opening extending through the second interlayer insulating film, the first interlayer insulating film, the first gate insulating film and the first-buffer upper layer, and a separation structure in the opening, the separation structure including a first separation layer having a same stacked structure as the first-buffer upper layer, a second separation layer having a same stacked structure as the first gate insulating film, and a third separation layer having a same stacked structure as the first gate electrode.

Display apparatus having a substrate hole

A display apparatus includes a substrate including a penetrating area including a substrate hole, and a separating area surrounding the penetrating area, a first buffer layer including a first-buffer lower layer on the substrate, and a first-buffer upper layer on the first-buffer lower layer, a first TFT including a first semiconductor pattern on the first-buffer upper layer, and a first gate electrode overlapping with the first semiconductor pattern under conditions that a first gate insulating film is interposed therebetween, and first source/drain electrodes connected to the first semiconductor pattern, a second TFT, a separation structure disposed in the separating area of the substrate while including a first separation layer having the same stacked structure as the first-buffer upper layer, a second separation layer having the same stacked structure as the first gate insulating film, and a third separation layer having the same stacked structure as the first gate electrode.

Discussed is a touch display device having an antenna disposed in a panel, thereby improving product reliability while reducing manufacturing cost. The touch display device includes a display unit including a plurality of pixels disposed in an active area, an encapsulation unit disposed on the display unit, the encapsulation unit being configured to seal the plurality of pixels, a touch sensor unit including a plurality of touch sensors disposed on the encapsulation unit, an antenna pattern disposed at an edge on the touch sensor unit in the state in which a planarization layer is interposed therebetween, the antenna pattern not overlapping a touch electrode and a touch routing line included in the touch sensor unit, and a ground plane disposed in an identical layer to any one metal layer belonging to the display unit, the ground plane overlapping the antenna pattern.

Touch display device

Disclosed is a method for forming a display device. The method includes forming an alignment mark on a front surface of a substrate having a display region and a non-display region surrounding the display region, forming an alignment protection pattern on a rear surface of the substrate such that the alignment protection pattern overlaps the alignment mark, and forming a light-shielding member in the non-display region on the rear surface of the substrate such that the light-shielding member forms a boundary with the alignment protection pattern.

Display device and method for manufacturing the same

Disclosed is a display device that includes a substrate having an active area and a dead area around the active area; an alignment mark on the inside surface of the substrate in a part of the dead area; and a light-shielding pattern on a rear surface of the substrate in the dead area, the light-shielding pattern including a mark hole for exposing the alignment mark. By providing the light-shielding pattern on a display surface in the dead area, the display device has expanded active display area and improved visual appreciation.
