Abstract: A display apparatus includes: a substrate; a light-emitting diode (“LED”) disposed above the substrate; a pixel-defining layer disposed above the substrate and including a concave portion which defines a space in which the LED is disposed; a light guider disposed in the space and between the LED and a first inner side surface of the concave portion; and a light blocker disposed above the pixel-defining layer to cover a top portion of the LED. The LED is disposed a second inner side surface of the concave portion, which is opposite to the first inner side surface, and spaced apart from a center of the concave portion, and the light guider guides light emitted from the LED to a region adjacent to the second inner side surface of the concave portion.

Abstract: Provided is a method of manufacturing a thin-film transistor substrate, the method includes forming a semiconductor pattern layer on a substrate. A first insulating film is formed on the semiconductor pattern layer. A metal pattern layer including a gate electrode and first and second alignment electrodes respectively spaced apart from two sides of the gate electrode is formed on the first insulating film. A cover layer covering the gate electrode is formed. The first and second alignment electrodes are removed. A first doping process is performed by doping the semiconductor pattern layer with a first impurity by using the cover layer as a mask. The cover layer is removed. A second doping process is performed by doping the semiconductor pattern layer with a second impurity having a lower impurity concentration than the first impurity by using the gate electrode as a mask.
