Abstract: A display device includes a first substrate, a first connection line disposed on a surface of the first substrate, a thin film transistor layer disposed on the first connection line, the thin film transistor layer including a plurality of thin film transistors, a first pad portion disposed on another surface of the first substrate, and a plurality of conductive parts disposed in the first substrate, including a material different from those of the first connection line and the first pad portion, and electrically connecting the first connection line and the first pad portion. The plurality of conductive parts include carbon nanotubes.

Abstract: A transparent organic light-emitting display device may include a lower transparent substrate having a pixel region and a boundary region disposed between adjacent pixel regions, a solar cell disposed on the lower transparent substrate, a display structure disposed on the solar cell, and an overcoat layer disposed between the solar cell and the display structure, in which the overcoat layer electrically insulates the display structure from the solar cell.

Abstract: A polarizer includes a base substrate and a wire grid array disposed on the base substrate. The wire grid array includes a plurality of linear patterns that extend in a first direction and are spaced apart from each other in a second direction crossing the first direction. The linear patterns include a metal layer and a metal oxide layer including an oxide of a metal included in the metal layer.

Abstract: A method of manufacturing a display substrate includes forming a gate electrode on a base substrate, forming an active pattern which includes an oxide semiconductor and overlaps with the gate electrode, forming an etch stopper which partially covers the active pattern, and performing a plasma treatment process to promote a reduction reaction to portions of the active pattern exposed by the etch stopper, thereby forming a source electrode and a drain electrode.
