Abstract: A display device includes a base substrate, a first transistor, a second transistor, an organic light emitting diode, and a capacitor electrically connected to the first thin film transistor. The first transistor includes a first semiconductor pattern below a first interlayer insulation layer and a first control electrode above the first interlayer insulation layer and below a second interlayer insulation layer. The second transistor includes a second control electrode above the first interlayer insulation layer and below the second interlayer insulation layer. A second semiconductor pattern is above the second interlayer insulation layer.

Abstract: A display apparatus includes: a substrate on which a first area, a second area spaced apart from the first area, and a bending area between a first area and a second area and bent along a bending axis are defined; a first thin-film transistor (“TFT”) and a second TFT; and a first conductive layer and a second conductive layer. The first TFT includes: a first active layer including polycrystalline silicon; a first gate electrode; and a first electrode disposed at a level which is the same as a level of the first conductive layer, and the second TFT includes: a second active layer including an oxide semiconductor; a second gate electrode; and a second electrode disposed at a level which is the same as a level of the second conductive layer.

Abstract: A liquid crystal cell panel includes a first substrate from which is formed a thin film transistor array substrate, the first substrate including a plurality of unit cells and test terminals which respectively correspond to the unit cells, and a second substrate which faces the first substrate and from which is formed a color filter substrate. The first substrate further includes a first cutting pattern at each of a plurality of corners thereof, and the second substrate includes a second cutting pattern at each of a plurality of corners thereof, the second cutting patterns corresponding one-to-one with the first cutting patterns. Corresponding first and second cutting patterns cross each other in a plan view, and the crossing first and second cutting patterns expose a test terminal adjacent to the crossing first and second cutting patterns to outside the liquid crystal cell panel.
