摘要： A display device includes a display panel and a light emitting device to supply light to the display panel. The light emitting device includes a light emitting element emitting a first light and a fluorescent layer receiving the first light, transmitting a portion of the first light, converting a remaining portion of the first light to a second light having a wavelength range different from the first light, and emitting the second light. The second light emitted by the fluorescent layer has a full width at half maximum equal to or larger than 110 nanometers (nm) and a light emission spectrum having a peak wavelength within a wavelength range of about 530 nm to about 560 nm. The second light has a light emission intensity corresponding to 10 to 30 percent of a peak light emission intensity of the first light.

摘要： A display device includes a display panel which displays an image, a backlight unit which supplies the display panel with light, an upper cover, and a lower cover. The upper and lower covers accommodate the display panel and the backlight unit. The backlight unit includes light guide plates spaced apart from each other, a light source part, an optical member and an optical diffusion member overlapping a space between the light guide plates. The optical diffusion member includes a diffusing part and a supporting part. The diffusing part faces the optical member, overlaps the space between the light guide plates, and diffuses light emitted from the light source part toward the optical member through the space between the light guide plates. The supporting part protrudes from a surface of the diffusing part which is opposite to the optical member, and is in a space between the light sources.

摘要： A display apparatus includes a light guide plate, a light source unit and a display panel. The light guide plate includes an incident surface, an exit surface and an opposite surface opposite to the exit surface and guides a light incident into the incident surface toward the exit surface. The light source unit includes a light source which generates light and is disposed adjacent to the incident and has an emitting surface inclined with respect to the incident surface. An extension line of a normal line of the emitting surface passes through the opposite surface, and the light is incident into the incident surface while being inclined toward the opposite surface. The display panel displays an image by receiving the light emitted from the exit surface.
