Light source unit, display apparatus and lighting apparatus
An example light source unit, comprising: a light emitting plate that emits light toward a front; an optical sheet that is separated from and faces a front surface of the light emitting plate; a support part that supports an edge portion of the optical sheet; and a holding section that faces an edge portion of a front or a back side of the optical sheet and holds the optical sheet.
1. A display apparatus, the display apparatus comprising:
a display panel displaying an image;
a light emitting plate that emits light toward the display panel;
an optical sheet that is separated from and faces a front surface of the light emitting plate between the display panel and the light emitting plate;
a support part which includes a panel support member supporting a back edge portion of the display panel and a sheet support member facing a front edge portion of the light emitting plate and supporting a back edge portion of the optical sheet; and
a holding section that is disposed on the back of the display panel or on the front of the light emitting plate and that faces an edge portion of a front side or a back side of the optical sheet and holds the optical sheet, wherein the holding section adheres to the optical sheet,
wherein an area of the display panel that is supported by the panel support member and an area of the optical sheet that is supported by the sheet support member do not overlap in a front-back direction and the support part further comprises a connecting part that connects an end portion of the panel support member closer to the display panel and an end portion of the sheet support member far from the optical sheet.
2. The display apparatus according to claim 1 , further comprising a spacer that is provided between the light emitting plate and a back edge portion of the sheet support member.
3. The display apparatus according to claim 1 , further comprising a light emitting diode, wherein light emitted from the light emitting diode enters into the light emitting plate and emits from the light guide plate.
4. The display apparatus according to claim 1 , wherein the holding section includes a thermoplastic elastomer member or a double-sided tape.
5. The display apparatus according to claim 1 , wherein the holding section includes a convex shape and a concave shape that are formed on a place of the sheet support member facing the edge portion of the optical sheet.
6. The light source unit according to claim 1 , wherein the optical sheet is formed in a laterally long rectangular shape, and the holding section is provided on the long edge part of the optical sheet.
7. A lighting apparatus, the lighting apparatus comprising:
a transmissive panel having light transmittance;
a light emitting plate that emits light toward the transmissive panel;
an optical sheet that is separated from and faces a front surface of the light emitting plate between the transmissive panel and the light emitting plate;
a support part which includes a panel support member supporting a back edge portion of the transmissive panel and a sheet support member facing a front edge portion of the light emitting plate and supporting a back edge portion of the optical sheet; and
a holding section that is disposed on the back of the transmissive panel or on the front of the light emitting plate and that faces an edge portion of a front side or a back side of the optical sheet and holds the optical sheet, wherein the holding section adheres to the optical sheet,
wherein an area of the transmissive panel that is supported by the panel support member and an area of the optical sheet that is supported by the sheet support member do not overlap in a front-back direction and the support part further comprises a connecting part that connects an end portion of the panel support member closer to the transmissive panel and an end portion of the sheet support member far from the optical sheet.
8. The lighting apparatus according to claim 7 , further comprising a light emitting diode, wherein light emitted from the light emitting diode enters into the light emitting plate and emits from the light guide plate.
9. The lighting apparatus according to claim 8 , wherein the light emitting diode is disposed opposite to a peripheral surface of the light emitting plate.
10. The lighting apparatus according to claim 8 , wherein the light emitting diode is disposed opposite on a surface of a back light chassis opposite to the light emitting plate.
11. The lighting apparatus according to claim 7 , further comprising a spacer that is provided between the light emitting plate and a back edge portion of the sheet support member.
12. The lighting apparatus according to claim 7 , wherein the holding section includes a thermoplastic elastomer member or a double-sided tape.
13. The lighting apparatus according to claim 7 , wherein the holding section includes a convex shape and a concave shape that are formed on a place of the sheet support member facing the edge portion of the optical sheet.
14. The lighting apparatus according to claim 7 , wherein the optical sheet is formed in a laterally long rectangular shape, and the holding section is provided on the long edge part of the optical sheet.
