  • Patent number: 8962156
    Abstract: An organic EL device includes an organic EL emitter that emits blue light and a blue color filter through which the light emitted from the organic EL emitter passes. The blue color filter contains a coloring material selected from the group consisting of a triarylmethane dye, a lake pigment, a copper-phthalocyanine pigment, and a mixture of a copper-phthalocyanine pigment and a dioxazine pigment. The chromaticity of the light that has passed through the blue color filter after being emitted from the organic EL emitter, is in the range defined by lines connecting three chromaticity coordinates (0.150, 0.060), (0.143, 0.031), and (0.130, 0.049) on the CIE chromaticity diagram.

  • Patent number: 8946681
    Abstract: An organic EL device includes an organic EL emitter that emits blue light and a blue color filter through which the light emitted from the organic EL emitter passes. The blue color filter contains a coloring material selected from the group consisting of a methine dye, a copper-phthalocyanine pigment, and a mixture of a copper-phthalocyanine pigment and a dioxazine pigment. The chromaticity of the light, the light that has passed through the blue color filter after emitted from the organic EL emitter, is in the range defined by lines connecting three chromaticity coordinates (0.140, 0.080), (0.136, 0.040), and (0.118, 0.070) on the CIE chromaticity diagram.

  • Patent number: 8111397
    Abstract: A plate inspection system and a plate inspection method with which irregularities in phase difference caused in a retardation layer can be efficiently detected. The inspection system is for inspecting a plate to be inspected having a retardation layer. The plate inspection system comprises a polarized-light source for irradiating a polarized light and an observation-side polarizer placed on the observation side. In the inspection system, a plate to be inspected is placed between the polarized-light source and the observation-side polarizer so that the plate to be inspected is irradiated with polarized light from the polarized-light source. The position of at least the observation-side polarizer or the plate to be inspected is changeable relative to the polarized-light source.

  • Patent number: 7961273
    Abstract: The invention provides a retardation-controlling optical member that includes a retardation layer obtained by aligning and fixing crosslinkable liquid crystal molecules and columnar structures disposed on the retardation layer. When a liquid crystal cell is formed by use of the retardation-controlling optical member, the columnar structures are effectively inhibited from subsiding in the retardation layer to locally make the cell gap smaller even when pressure is externally applied in a thickness direction of the liquid crystal cell. A sum total of lower bottom areas of columnar structures disposed on a retardation layer is made larger sufficiently compared to a total area of, in particular, an effective display region of a retardation layer surface where the columnar structures are disposed, whereby pressure applied from a thickness direction is dispersed.
