  • Publication number: 20120097982
    Abstract: A lighting device including an electroluminescent (EL) material is connected to an external power supply easily and the convenience is improved. In a lighting device having a light-emitting element including an electroluminescence (EL) layer, a housing including a light-emitting element has a terminal electrode electrically connected to the light-emitting element on a peripheral end portion. The terminal electrode provided on the housing so as to be exposed to the outside is in contact with a terminal electrode for the external power supply, so that the external power supply and the light-emitting element are electrically connected to each other and power can be supplied to the lighting device.

  • Publication number: 20090142510
    Abstract: A first supporting substrate on a front surface of which a reflective layer having an opening is formed and a second supporting substrate on a front surface of which a light absorption layer patterned into island or stripe shapes and a material layer over the light absorption layer are formed are prepared, the first and second supporting substrates are disposed so that the opening of the reflective layer and the light absorption layer overlap with each other and the reflective layer is in contact with a back surface of the second supporting substrate, the second supporting substrate and a deposition target substrate are disposed so that the front surface of the second supporting substrate faces the deposition target substrate, and the material layer is attached to the deposition target substrate by irradiating the back surface of the first supporting substrate with light and by sublimating the material layer.
