    Abstract: A method of manufacturing a display apparatus is presented. The method includes sequentially forming a conductive layer and a low reflection layer above a substrate; forming a first low reflection layer including a lower layer having conductivity and an upper layer above the lower layer, a pixel electrode, and a low reflection etching layer above the pixel electrode by patterning the conductive layer and the low reflection layer; forming a pixel-defining layer above the first low reflection layer and having an opening exposing at least a part of the low reflection etching layer; exposing the pixel electrode by etching at least a part of the low reflection etching layer by using the pixel-defining layer as a mask; forming an intermediate layer above the exposed pixel electrode, the intermediate layer comprising an organic emission layer; and forming an opposite electrode above the intermediate layer.

    Abstract: Provided is a thin film transistor array substrate having at least one thin film transistor. The thin film transistor includes a semiconductor layer having a channel area with a first doping concentration on a substrate, a source-drain area disposed at opposite sides of the channel area and with a second doping concentration greater than the first doping concentration, and a substantially undoped area extending from the source-drain area. The substrate has a gate insulating layer on the semiconductor layer and a gate electrode disposed on the gate insulating layer and overlapping the channel area in at least some portions. The substrate has a source electrode and a drain electrode, each insulated from the gate electrode and electrically connected to the source-drain area. The gate electrode includes a first gate electrode layer and a second gate electrode layer, wherein the second gate electrode layer is thicker than the first gate electrode layer.

    Abstract: A display apparatus includes a substrate, a display unit, a pad portion, and a connection wire. The display unit is on the substrate. The display unit includes a pixel circuit and a display device electrically connected to the pixel circuit. The pad portion is at one side of a peripheral area outside the display unit. The pad portion includes a first conductive layer, a second conductive layer arranged on and electrically connected to the first conductive layer, and a third conductive layer arranged on and electrically connected to the second conductive layer. The connection wire connects the pad portion and the display unit to each other to transmit a signal input to the pad portion to the display device. The connection wire includes a same material as that of the first conductive layer.
