a plurality of reflection patterns on the base substrate in the light blocking area and spaced from each other; and a light blocking layer covering the reflection patterns and configured to block light. ### Claim 2 (depends on 1) The window member of claim 1, wherein each of the reflection patterns comprises a plurality of layers having different refractive indices from each other. ### Claim 3 (depends on 2) The window member of claim 2, wherein each of the reflection patterns further comprises: a first layer on the base substrate and configured to transmit light; and a second layer on the first layer and having a refractive index different from a refractive index of the first layer. ### Claim 4 (depends on 3) The window member of claim 3, wherein the refractive index of the first layer is greater than the refractive index of the second layer. ### Claim 5 (depends on 4) The window member of claim 4, wherein each of the first and second layers has the refractive index in a range from about 1.3 to about 2.4, and a difference between the refractive index of the first layer and the refractive index of the second layer is equal to or greater than about 0.1. ### Claim 6 (depends on 3) The window member of claim 3, wherein the first layer has a thickness different from a thickness of the second layer in each of the reflection pattern. ### Claim 7 (depends on 3) The window member of claim 3, wherein each of the reflection patterns further comprises an etch stop layer on the second layer. ### Claim 8 (depends on 1) The window member of claim 1, wherein each of the reflection patterns has a single-layer structure comprising silver, aluminum, or aluminum alloy. ### Claim 9 (depends on 1) The window member of claim 1, wherein the reflection patterns are color patterns that reflect lights having different colors from each other. ### Claim 10 A method of manufacturing a window member, the method comprising: sequentially forming a first layer and a second layer on a base substrate having a light transmitting area and a light blocking area surrounding the light transmitting area, the first and second layers having different refractive indices from each other; patterning the first and second layers to form a plurality of reflection patterns in the light blocking area; and forming a light blocking layer covering the reflection patterns and configured to block light. ### Claim 11 (depends on 10) The method of claim 10, wherein the forming of the plurality of reflection patterns comprises: forming an etch stop layer on the second layer; patterning the etch stop layer to form a plurality of etch stop layer patterns in the light blocking area; and patterning the first and second layers corresponding to the etch stop layer patterns. ### Claim 12 (depends on 11) The method of claim 11, wherein the refractive index of the first layer is greater than the refractive index of the second layer. ### Claim 13 (depends on 12) The method of claim 12, wherein each of the first and second layers has the refractive index in a range from about 1.3 to about 2.4, and a difference between the refractive index of the first layer and the refractive index of the second layer is equal to or greater than about 0.1. ### Claim 14 (depends on 11) The method of claim 11, wherein the etch stop layer transmits light. ### Claim 15 A display device comprising: a display panel; and a window member having a light transmitting area and a light blocking area surrounding the light transmitting area, the window member comprising: a base substrate having the light transmitting area and the light blocking area surrounding the light transmitting area; a plurality of reflection patterns formed on a surface of the base substrate facing the display panel in the light blocking area; and a light blocking layer covering the reflection patterns and configured to block light. ### Claim 16 (depends on 15) The display device of claim 15, wherein each of the reflection patterns comprises a plurality of layers having different refractive indices from each other. ### Claim 17 (depends on 16) The display device of claim 16, wherein each of the reflection patterns further comprises: a first layer on the base substrate; and a second layer on the first layer and having a refractive index different from a refractive index of the first layer. ### Claim 18 (depends on 17) The display device of claim 17, wherein each of the reflection patterns further comprises an etch stop layer on the second layer. ### Claim 19 (depends on 15) The display device of claim 15, wherein each of the reflection patterns has a single-layer structure comprising silver, aluminum, or aluminum alloy. ### Claim 20 (depends on 15) The display device of claim 15, wherein the reflection patterns are color patterns that reflect lights having different colors from each other.
