    Abstract: Uneven brightness is less likely to be caused in a lighting device. The lighting device includes LEDs 17, a chassis 14 housing the LEDs 17, and a chassis reflection sheet 22 provided on an inner surface of the chassis 14 and reflecting light from the LEDs 17. The chassis reflection sheet 22 includes a sheet bottom portion 31 extending along a front surface of a bottom plate 14a and a sheet sloped portion 32 extending from a peripheral edge of the bottom portion 31. The sloped portion 32 is inclined with respect to the bottom portion 31 toward a light exit side of a backlight device 12. The chassis reflection sheet 22 includes a border portion F2 and adjacent portions F1, F3. The border portion includes a borderline L between the bottom portion 31 and the sloped portion 32 and an area along the borderline L, and the adjacent portions F1, F3 are provided in adjacent to the border portion F2 so as to be farther from the borderline L. Light reflectance is higher in the border portion F2 than in the adjacent portions F1, F3 on the surface of the chassis reflection sheet 22 close to the light source.

    Abstract: A display apparatus is provided and includes a display panel, and a backlight unit supplying light from a rear of the display panel. The backlight unit includes a light source, a circuit board layer, a reflection layer, a pattern layer, and a vacant layer. The circuit board layer has the light source seated thereon. The reflection layer is formed on the circuit board layer to reflect light emitted from the light source. The pattern layer is positioned on a top surface of the light source. The vacant layer is formed between the reflection layer and the pattern layer.
