Lighting device and display device
A lighting device ( 100 A) includes: at least one light-emitting device ( 10 ) that emits light; and a light guide plate ( 20 ) having a light-receiving end face ( 20 a ) that receives light which is emitted from the at least one light-emitting device ( 10 ) and an outgoing face ( 20 b ) that crosses the light-receiving end face ( 20 a ). The lighting device ( 100 A) further includes a substrate ( 30 ) of a rectangular ring shape, the substrate having four side portions ( 30 a, 30 b, 30 c, 30 d ). The at least one light-emitting device ( 10 ) is provided on the substrate ( 30 ).
1. A display apparatus comprising:
a lighting device including:
at least one light-emitting device that emits light; and
a light guide plate having a light-receiving end face that receives light which is emitted from the at least one light-emitting device and an outgoing face that emits light which has entered into the light guide plate through the light-receiving end face, wherein,
the display apparatus further comprises a display panel provided on the outgoing face side of the light guide plate;
the lighting device further includes a substrate of a rectangular ring shape, the substrate having four side portions;
the at least one light-emitting device is provided on the substrate;
each of the four side portions of the substrate has an angular C-shaped cross section; and
the substrate includes a guide portion which causes the display panel to be positioned relative to the lighting device.
2. The display apparatus of claim 1 , wherein the at least one light-emitting device is disposed on one side portion among the four side portions of the substrate.
3. The display apparatus of claim 1 , wherein,
the at least one light-emitting device comprises a plurality of light-emitting devices; and
the plurality of light-emitting devices are disposed on two or more side portions among the four side portions of the substrate.
4. The display apparatus of claim 1 , wherein the substrate is made of a metal material.
5. The display apparatus of claim 1 , wherein,
the substrate includes a corner portion where two side portions among the four side portions intersect with each other; and
the guide portion is provided in the corner portion.
6. The display apparatus of claim 1 , wherein,
as viewed from a normal direction of a display surface, the guide portion has a L-shape.
