Abstract: If a black matrix is thinned down in order to increase the aperture ratio, color mixture is likely to occur in which during monochromatic representation a desired color from relevant sub-pixels and a different color from adjacent sub-pixels appear to be mixed together when viewed obliquely. A display device includes a display panel and a light source. The display panel includes an array substrate, an opposite substrate, and a liquid crystal layer. The opposite substrate includes a first light blocking layer and a colored layer. The array substrate includes a second light blocking layer and a signal wiring layer. The first light blocking layer, the second light blocking layer, and the signal wiring layer are disposed between sub-pixels of different colors. The second light blocking layer is disposed close to the liquid crystal layer. A distance between top surfaces of the first and second light blocking layers is decreased.
