Thin film electroluminescent device |
摘要 |
A thin film electroluminescent (EL) device includes a pair of opposing electrodes formed on a substrate of a transparent electrical insulator, and an EL layer formed between the electrodes and covered at both surfaces with insulating layers respectively. Strontium sulfide is used as a host material of the EL layer, and its crystals tend strongly to have a (200) orientation, so that the resistance to free transit of electrons participating in emission of luminescence is substantially eliminated to ensure a higher brightness.
