Abstract
An object is to provide a display device which has high visibility and has a touch recognition function with a high degree of accuracy, by combining a liquid crystal layer where liquid crystals are dispersed in a polymer and a light emitting element. In a display device using a liquid crystal layer where liquid crystals are dispersed in a polymer, a light-transmitting spacer is provided so as to overlap with a light receiving element which has a touch recognition function. The light-transmitting spacer can prevent light incident on the light receiving element from being dispersed by the liquid crystals, while maintaining a cell gap in the liquid crystal layer, and thus achieve a touch recognition function with a high degree of accuracy with high visibility.
