Abstract

A display device includes a display panel including a plurality of sub-pixel areas, and a light travel-direction changing layer including a plurality of light-transmitting patterns for changing the travel direction of light emitted from the plurality of sub-pixel areas, respectively. In this connection, a central point of a light-emission face of each of the plurality of light-transmitting patterns is defined as a point at which a virtual face corresponding to the light-emission face of each of the plurality of light-transmitting patterns contacts an optimal light-path line connecting a sub-pixel area corresponding to each light-transmitting pattern and a central point of the viewing area to each other. In this way, light from the sub-pixel area may pass through the light-transmitting pattern and may be directed toward the central point of the viewing area. Thus, the display quality in the viewing area may be improved.
