Electroluminescence element

Abstract

Abstract PURPOSE:To make effective insulation without any loss of light transmission and extend lifetime by providing a strong dielectric liquid crystal layer as an insulation layer between a luminous layer and a transparent electrode. CONSTITUTION:A rear electrode 3 is screen printed on a water retention film 8 and insulation paste is printed on the rear electrode 3. Then, a drying process is applied thereto for forming an insulation layer 4. Luminous paste is printed on the insulation layer 4 and dried for forming a luminous layer 5. The ends of the layer 5 is sealed with a sealing material 6. Furthermore, a strong dielec tric liquid crystal layer 7 is printed on the luminous layer 5. A base film 1 having a transparent electrode 2 is placed on the liquid crystal layer 7 and work for dislocating a film in a single direction is repeated several times, there by orienting the liquid crystal layer 7 unidirectionally. Furthermore, the film 8 is placed thereon and the whole is sandwiched and sealed with moisture proof films 9 and 9. According to the aforesaid construction, it is possible to form an electroluminescence element having high insulation quality without any loss of light transmission.
