Abstract: A display device including a substrate, a source electrode and a drain electrode on the substrate, the source electrode and the drain electrode being spaced apart from each other, a first layer on the source electrode or the drain electrode, a second layer directly on the first layer, and a first electrode on the second layer. A step difference between a top of the first layer and a top of the drain electrode is 100 Å or less.

Abstract: An input sensing unit includes a base including light-transmitting areas and non-light transmitting areas. A light absorbing pattern is provided corresponding to the non-light transmitting areas and is configured to absorb incident light. A sensing electrode overlaps the light absorbing pattern. The light absorbing pattern has an aperture for exposing a light-transmitting area of the light-transmitting areas. A boundary of the aperture and an outer boundary of the light-transmitting area are spaced apart from each other. The input sensing unit has improved viewing angle/luminance ratio and improved characteristics of reflective color.
