A display apparatus including a heteromorphy lens disposed on a path of light emitted from a light-emitting device, a side surface of the heteromorphy lens toward a first direction has a shape different from a side surface of the heteromorphy lens toward a second direction perpendicular to the first direction, so that light can be condensed in the first direction and diffused in the second direction due to the heteromorphy lens, and the reduction in luminance can be minimized, and the viewing angle can be limited.

Display apparatus having heteromorphy lens

An LCD device includes plurality of gate lines and data lines crossing each other to define pixel regions on a substrate. A thin film transistor (TFT) resides at a crossing portion of the gate lines and the data lines and a pixel electrode is electrically connected with the TFT. The TFT includes a gate electrode, a gate insulation layer on the gate electrode and a semiconductor layer on the gate insulation layer. A portion of the data line and the semiconductor layer form a composite layer between adjacent pixel electrodes in which a line width of data line is the same as a line width of semiconductor layer. A method of fabricating the LCD device includes etching a passivation layer using a mask pattern and etching the semiconductor layer using the mask pattern and a portion of the data line as an etch mask to form the composite layer.
