Claim Text:
1. A display device comprising: an upper substrate having gate lines and data lines, wherein each of a plurality of crossing portions of a corresponding gate line and data line is at a thin film transistor connected to the corresponding gate line and data line; a lower substrate on a lower surface of the upper substrate and exposing a part of the lower surface of the upper substrate; and a first reflection preventing layer overlapping the gate lines, and a second reflection preventing layer overlapping the data lines formed on the upper substrate so as to prevent external light from being reflected by the gate lines and the data lines, wherein the first reflection preventing layer has a pattern corresponding to the gate lines, wherein the second reflection preventing layer has a pattern corresponding to the data lines, wherein the gate lines directly contact the first reflection preventing layer, wherein, in a cross-sectional view, a width of each of separate portions of the first reflection preventing layer is equal to a width of the corresponding gate line, and a width of each of separate portions of the second reflection preventing layer is equal to a width of the corresponding data line, and wherein a gate insulating film is on both the first reflection preventing layer and the gate lines.
