| titleOfInvention | Thin film EL device |
| abstract | (57) [Abstract] [Purpose] To obtain a thin-film EL device that improves the brightness of full-color and multi-color thin-film EL devices. [Structure] In a thin film EL device using strontium sulfide as a base material of a light emitting layer 4, the iron content of the film forming material of the light emitting layer 4 is 10 ppm or less, the cobalt content is 10 ppm or less, the calcium content is 100 ppm or less, and the barium content is To 100 ppm or less, the carbon content to 1 atomic percent or less, and the nickel content to 10 ppm or less. |
