摘要： A display apparatus includes a display panel and a backlight unit. The backlight unit includes a first layer (21), a light source (22), a light guide layer (24) having a hollow (242) for receiving the light source, the light guide layer being to transmit and diffuse light emitted from the light source, and a reflection member e.g. a reflector (241,241a) to reflect at least one portion of the light emitted from the light source toward the inside of the light guide layer. A position of the light emitted from the light source may pass through the light screening layer (25) to proceed toward the display panel. The forming part (253) may have an inclined structure. A second layer (23) extracts or reflects the light emitted from the light source toward the display panel. A light extraction pattern (231) diffuses the light emitted from the light source up to the adjacent light source at uniform brightness.
