Abstract
An upper area over an element substrate is sealed by a sealing substrate to which a desiccant is fixed on an internal surface of the sealing substrate. A substance prepared by dispersing moisture absorbent grains into an adhesive made of resin is used as the desiccant. Further, the size of the moisture absorbent grains is defined to be equal to or smaller than 10 μm. In this manner, the desiccant can be prevented from cracking due to temperature variations.
Claims11
A display apparatus in which display operation is carried out by controlling emission of each pixel arranged in a matrix, the apparatus comprising:
- an element substrate on which a luminous element is formed for each of the pixels;
- a sealing substrate on which a protrusion is formed in a surrounding area thereof, the protrusion being adhered to the periphery of said element substrate so as to seal an upper space over said element substrate, and
- a desiccant fixed on an internal surface of the sealing substrate opposed to the element substrate so as to make the upper space located over the element substrate dry, wherein
- said desiccant consists of an adhesive made of resin and moisture absorbent grains dispersedly mixed into the adhesive, and
- the size of said moisture absorbent grains is equal to or smaller than 10 μm.
A desiccant which absorbs moisture consisting of:
- an adhesive of resin, and
- moisture absorbent grains dispersedly mixed into the adhesive, wherein
- the diameter of said moisture absorbent grains is equal to or smaller than 10 μm.
