Abstract: A display apparatus includes a display panel configured to display an image. A light guide plate is disposed below the display panel. The light guide plate has a light incident surface. A light source is disposed adjacent to the light incident surface of the light guide plate to generate first light. A light conversion layer is disposed between the light guide plate and the display panel to convert a wavelength band of incident light. An optical filter layer is disposed between the light guide plate and the light conversion layer to selectively transmit or reflect incident light.
