Resin component holding member, image display device, and light diffusion member

1. A resin component holding member made of a metal material and configured to hold a resin component, wherein the resin component holding member is subjected to chemical treatment, the resin component holding member comprising:

a region with which the resin component is in contact, the region having a configuration for preventing alkaline residue caused by the chemical treatment from permeating into the resin component; and

a plurality of grooves formed adjacent to the region, the plurality of grooves being used as passages connecting inside and outside of the resin component holding member when the resin component holding member holds the resin component.

2. The resin component holding member according to claim 1 , wherein at least the region with which the resin component is in contact includes a region where a surface is cut such that the metal material is exposed.

3. The resin component holding member according to claim 1 , wherein at least the region with which the resin component is in contact includes a region where surface treatment through which the alkaline residue cannot remain is performed instead of the chemical treatment.

4. The resin component holding member according to claim 1 , wherein a spacer for separating the resin component from a surface subjected to the chemical treatment is provided in at least the region with which the resin component is in contact.

5. The resin component holding member according to claim 1 , wherein, on at least the region with which the resin component is in contact, a plurality of projection portions for separating the resin component from a surface of the region are formed.

6. An image display device comprising:

a resin component; and

a resin component holding member made of a metal material and configured to hold the resin component,

wherein the resin component holding member is subjected to chemical treatment,

wherein the resin component holding member includes:

a region with which the resin component is in contact, the region having a configuration for preventing alkaline residue caused by the chemical treatment from permeating into the resin component; and

a plurality of grooves formed adjacent to the region, the plurality of grooves being used as passages connecting inside and outside of the resin component holding member when the resin component holding member holds the resin component.

7. The image display device according to claim 6 , wherein, in the resin component holding member, at least the region with which the resin component is in contact includes a region where a surface is cut such that the metal material is exposed.

8. The image display device according to claim 6 , wherein, in the resin component holding member, at least the region with which the resin component is in contact includes a region where surface treatment through which the alkaline residue cannot remain is performed instead of the chemical treatment.

9. The image display device according to claim 6 , wherein the resin component holding member includes a spacer, for separating the resin component from a surface subjected to the chemical treatment, provided in at least the region with which the resin component is in contact.

10. The image display device according to claim 6 , wherein, in the resin component holding member, on at least the region with which the resin component is in contact, a plurality of projection portions for separating the resin component from a surface of the region are formed.

11. The image display device according to claim 6 , wherein the resin component is a light diffusion member including a substrate made of a resin material.

12. The image display device according to claim 11 , wherein

the resin component holding member holds a first light diffusion member and a second light diffusion member disposed so as to be aligned with a step having a predetermined height with respect to the first light diffusion member, and includes, at a boundary between the first light diffusion member and the second light diffusion member, a wall portion corresponding to the step, and

a structure for inhibiting liquid dripping from the wall portion to the second light diffusion member is provided between a lower end of the wall portion and the second light diffusion member.

13. The image display device according to claim 11 , wherein a flat portion having no lens portion is formed at least an end portion, of the light diffusion member, held by the resin component holding member.

14. The image display device according to claim 13 , wherein the light diffusion member comprises:

a substrate made of resin;

a plurality of lens portions formed on at least one surface of the substrate; and

the end portion held by the resin component holding member.
