  • Patent number: 9357612
    Abstract: A lighting portion is attached to a reflective liquid crystal display portion. A first transparent substrate and a second transparent substrate made of a glass substrate etc. are attached to each other with a sealing layer coated on those peripheral portions therebetween. The back surface of the first transparent substrate is attached to the reflective liquid crystal display portion, and an organic EL element is formed on the front surface of the first transparent substrate. The organic EL element is sealed in a space surrounded by the first transparent substrate, the second transparent substrate, and the sealing layer. The organic EL element is formed in a region corresponding to a pixel region of the reflective liquid crystal display portion. A desiccant layer is formed on the front surface of the second transparent substrate.

  • Patent number: 8970461
    Abstract: Disclosed herein is a display including: a reflective image display section having pixels arranged in the display region; and a lighting device adapted to irradiate light to the image display section from diagonally in front, in which the light scattering characteristics in the display region are angle-dependent, and in which the lighting device irradiates light whose intensity distribution is adjusted so that when the display region displaying an image having an equal gray level is viewed from a given viewing position, the image luminance is uniform.

  • Patent number: 7247984
    Abstract: In an electroluminescence element, a layered structure is employed for an upper electrode including a first upper conductive layer formed through evaporation, a buffer layer, and a second upper conductive layer formed through sputtering. By interposing the buffer layer between the first and second upper conductive layers, damages to a light emitting element layer formed below the upper electrode and containing an organic material or the like having a low resisting characteristic against sputtering environment can be prevented while a high level of a charge injection efficiency to the light emitting element layer is maintained for charges such as electrons and holes, and, at the same time, a conductive layer can be formed with superior coverage and uniformity, to a sufficient thickness, and with superior productivity. The buffer layer may have a multi-layer structure.
