1. A display device comprising:
a display part including a display surface on which an image is displayed;
a light source part including a plurality of LEDs;
a lens mounted to cover the light source part and to refract and reflect a light of the light source part;
a reflection sheet provided on a rear surface side opposite to the display surface of the display part and configured to reflect the light refracted and reflected by the lens;
an optical sheet disposed between the display part and the reflection sheet and configured to be parallel to the display part; and
a rear frame configured to cover the reflection sheet on the rear surface side,
wherein the light source part is disposed in an upper portion of the display device in which the plurality of LEDs of the light source part are disposed to be arrayed in a longitudinal direction of the rear frame,
wherein a hollow light-guiding region is provided between the reflection sheet and the optical sheet, and
wherein a distance between the reflection sheet and the optical sheet is less in a lower portion than in the upper portion, and a direction extending from the upper portion to the lower portion is orthogonal to the longitudinal direction,
wherein in the longitudinal direction of the rear frame, the lower portion of the rear frame is configured such that a distance between the optical sheet and the lower portion of the rear frame at both ends is greater than a distance between the optical sheet and the rear frame in a middle portion, wherein
a distance between the optical sheet and the rear frame gradually decreases from the lower portion to a lower side edge of the display device, and
a distance between the optical sheet and the rear frame in the lower portion is less than a distance between the optical sheet and the rear frame in the upper portion.
2. The display device according to claim 1 , wherein a component part is mounted on a rear surface side of the lower portion of the rear frame.
3. The display device according to claim 2 , wherein the component part includes a substrate on which a speaker and an electronic component are mounted.
4. The display device according to claim 1 , wherein the distance between the reflection sheet and the optical sheet is less at both ends in the longitudinal direction of the reflection sheet than in the middle portion.
5. The display device according to claim 1 , wherein the light source part is disposed on a rear surface side of an image display region surrounded by a bezel of the display part.
6. The display device according to claim 1 ,
wherein the display device further comprises a reflection member mounted to extend in the longitudinal direction of the display part in a direction in which the plurality of LEDs extends and to reflect light emitted from the lens.
7. The display device according to claim 6 , wherein the reflection member is disposed to slope with respect to the optical sheet and is configured to reflect light reflected by the optical sheet in the light-guiding region toward the optical sheet.
8. The display device according to claim 1 ,
wherein the rear frame slopes from the middle portion to the end portions to be close to the optical sheet, and
wherein a slope angle of the rear frame with respect to the optical sheet is an acute angle.
9. The display device according to claim 8 , wherein the slope angle of the rear frame with respect to the optical sheet is equal to or less than 35 degrees.
10. The display device according to claim 1 , further comprising:
a cover configured to cover the light source part on an upper surface side and a rear surface side,
wherein a first air vent is provided on the upper surface side of the cover.
11. The display device according to claim 10 , wherein an opening is provided on the rear surface side of the cover.
12. The display device according to claim 10 ,
wherein a second air vent is provided on an upper surface side of the rear frame, and
wherein the first and second air vents are provided at positions at which the first and second air vents overlap in a plan view.
13. The display device according to claim 10 ,
wherein a second air vent is provided on an upper surface side of the rear frame, and
wherein the first and second air vents are provided at positions at which the first and second air vents do not overlap in a plan view.
14. The display device according to claim 1 ,
wherein the light source part is mounted on the rear frame via a light source base, and
wherein the light source base has a heat dissipation greater than a heat dissipation of the rear frame.
15. The display device according to claim 1 , wherein in the middle portion, a space is formed in a rear surface side of the lower portion of the rear frame, and a component part is mounted in the space.
