Abstract: A display device includes a substrate, a first thin-film transistor (TFT), a first organic light-emitting diode (OLED), and a second OLED. The TFT is on a first surface of the substrate and includes a first output electrode and a second output electrode. The OLED is on the first surface of the substrate and is electrically connected to the first output electrode of the TFT. The second OLED is on a second surface of the substrate and is electrically connected to the second output electrode of the TFT.

Abstract: A wire grid polarizer plate includes: a transparent substrate through which incident light is transmitted; and a partition wall member on the transparent substrate and at which first polarized light is transmitted and second polarized light perpendicular to the first polarized light is reflected. The partition wall member is defined by: first partition walls spaced apart from each other on the transparent substrate, the first partition walls formed of a first metal; second partition walls respectively on the first partition walls, the second partition walls formed of a second metal having strength greater than that of the first metal; and third reinforced partition walls respectively on the second partition walls and having a stepped cross-sectional structure, the third partition walls formed of an oxide of the first metal, the oxide of the first metal having strength greater than the strength of the second metal.
