EL display device and electronic device
View Patent ↗A cover member is adhered onto a substrate on which an EL element is formed with a filler as an adhesive. Further, a sealing member is provided so as to cover a side surface (an exposing surface) of the filler, and a frame member is adhered using the sealing member. With this structure, the EL element is completely sealed by the filler, and shut from moisture and the like from the outside. Thus, deterioration of an EL layer due to oxidization can be prevented.
1. An electroluminescence (“EL”) display device comprising a substrate on which an EL element is formed, a cover member, a filler for adhering said substrate on which the EL element is formed to said cover member, a sealing member for covering a side surface of said filler, and a frame member adhered with said sealing member, wherein a drying agent is included in said filler and said drying agent has a granular shape with an average diameter of 100 μmØ.
2. An electroluminescence (“EL”) display device comprising an active matrix substrate on which a thin film transistor (“TFT”) and an EL element electrically connected with the TFT are formed, a cover member, a filler for adhering said active matrix substrate to said cover member, a sealing member for covering a side surface of said filler, and a frame member adhered with said sealing member, wherein a drying agent is included in said filler and said drying agent has a granular shape with an average diameter of 100 μmØ.
3. An electroluminescence (“EL”) display device comprising a substrate on which an EL element composed of an anode arranged in a stripe, a cathode arranged in a stripe so as to be perpendicular to said anode, and an EL layer formed between said anode and said cathode, a cover member, a filler for adhering said substrate on which the EL element is formed to said cover member, a sealing member for covering a side surface of said filler, and a frame member adhered with said sealing member, wherein a drying agent is included in said filler and said drying agent has a granular shape with an average diameter of 100 μmØ.
