    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.

    Abstract: A display device includes a plurality of segmented display units arranged in a matrix, and a front display unit disposed on the plurality of segmented display units. The front display unit includes a plurality of transmission areas corresponding to main display areas of the plurality of segmented display units, and a supplementation display area corresponding to a separation area between the main display areas of adjacent segmented display units among the plurality of segmented display units. Due to the supplementation display area of the front display unit, the separation area between the main display areas of adjacent segmented display units may be prevented from being visible to a user. Therefore, the display device may realize both a large size screen and a high resolution.
