Abstract
A display apparatus includes a light source, a display panel, a light guide member, and an optical member. The light source is configured to generate light. The display panel is configured to display an image. The light guide member includes at least one surface adjacent to the light source. The optical member is between the light guide member and the display panel. The optical member includes a low refractive layer, a first cover layer, and a light conversion layer. The low refractive layer is on a light output surface of the light guide member and includes side surfaces. The first cover layer is on the low refractive layer and surrounds at least a portion of the side surfaces of the low refractive layer. The light conversion layer is on the first cover layer and is configured to covert a wavelength band of incident light.
