Abstract

An electroluminescent device includes a first substrate being provided with a plurality of luminescent elements, a second substrate facing the first substrate with the plurality of luminescent elements therebetween, a desiccating agent covering the face of the first substrate at the side facing the second substrate or of the second substrate at the side facing the first substrate, and a liquid-repellent portion surrounding the desiccating agent and being repellent to a coating liquid for forming the desiccating agent.

Claims (21)

1. An electroluminescent device comprising:

a first substrate on which a plurality of luminescent elements are formed;

a second substrate arranged on a side of the first substrate on which the plurality of luminescent elements are formed;

a plurality of optical members formed on the first substrate side of the second substrate;

a shielding film formed between the plurality of optical members;

a desiccating agent formed on the shielding film;

the plurality of optical members being provided with liquid repellency with respect to a solution of the desiccating agent; and

the shielding film being more lyophilic than the plurality of optical members with respect to the solution of the desiccating agent.

2. The electroluminescent device as set forth in claim 1 ,

at least part of the desiccating agent being positioned between the plurality of optical members.

3. The electroluminescent device as set forth in claim 1 ,

the plurality of optical members being arranged so as to respectively overlap the plurality of luminescent elements in plan view.

4. The electroluminescent device as set forth in claim 1 ,

the plurality of optical members selectively transmitting predetermined colored light.

5. The electroluminescent device as set forth in claim 1 ,

the plurality of optical members selectively transmitting predetermined polarized light.

6. An electronic device comprising the electroluminescent device as set forth in claim 1 .

7. The electroluminescent device as set forth in claim 1 ,

the liquid repellency of the plurality of optical members using fluorine.

8. The electroluminescent device as set forth in claim 1 ,

the desiccating agent physically contacting the shielding film.
