Mask, method of manufacturing mask, device for manufacturing mask, method of manufacturing layer of luminescent material, electro-optical device, and electronic device
This mask includes: a substrate in which an aperture is formed; a mask member which, along with being formed with a plurality of through holes, is joined to the substrate in correspondence to the aperture; and spacers which hold the substrate and the mask member with a predetermined gap between them.
1. A mask, comprising:
a substrate in which an aperture is formed;
a mask member which, along with being formed with a plurality of through holes, is joined to said substrate in correspondence to said aperture; and
spacers which are sufficiently rigid not to deform when pressed so as to hold said substrate and said mask member with a predetermined gap between them, wherein:
said spacers consist of a plurality of spherical bodies having a diameter that is substantially the same as said predetermined gap, and
said spacers are provided between said substrate and said mask member, so that each of said spacers contacts both said substrate and said mask member.
2. A mask according to claim 1 , wherein said spacers are disposed along with an adhesive in a junction region between said substrate and said mask member.
3. A mask according to claim 2 , wherein said substrate includes a transparent material.
4. A mask according to claim 2 , wherein the adhesive is photo-curing.
5. A mask according to claim 2 , wherein the adhesive is disposed at an outer peripheral side of said mask member.
6. A method of manufacturing a layer of luminescent material, wherein, as a mask which is used when forming a layer of luminescent material by vapor deposition, there is used:
a mask according to claim 1 .
