Frame, surface light source device, display device and electronic device
A frame includes a resin frame which surrounds at least a part of the side faces of a light guide plate; a reflection diffusion material which is added in the resin frame and reflects and diffuses light; and an absorption material which is added in the resin frame and absorbs light. The reflectance of the resin frame is equal to or greater than 30% and equal to or smaller than 80%.
1. A frame, comprising:
a resin frame which surrounds at least a part of the side faces of a light guide plate;
a reflection diffusion material which is added in the resin frame and reflects and diffuses light; and
an absorption material which is added in the resin frame and absorbs light,
wherein the reflectance of the resin frame is equal to or greater than 30% and equal to or smaller than 80%.
2. The frame according to claim 1 , wherein the reflectance of the resin frame is equal to or greater than 45% and equal to or smaller than 65%.
3. The frame according to claim 1 , wherein the reflection diffusion material is white pigment, and the absorption material is black pigment.
4. The frame according to claim 1 ,
wherein the reflection diffusion material is titanium oxide, and the absorption material is carbon.
5. A surface light source device, comprising:
the frame according to claim 1 ;
the light guide plate housed in the frame; and
a light source which is housed in the frame and which causes light to enter the light guide plate from a side face thereof.
6. A display device, comprising:
the surface light source device according to claim 5 ; and
a display panel which receives light emitted from the surface light source device.
7. An electronic device comprising the display device according to claim 6 .
