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.
