  • Patent number: 7916265
    Abstract: Within a reflective display section R, a part of a light that reaches a reflective electrode through a color filter exits to the outside through slits and a part of a light that reaches the reflective electrode through the slits exits to the outside through the color filter. In addition, a light reaching the reflective electrode through the color filter and exiting to the outside through the color filter, and a light having no opportunity to pass through the slits also can be observed. Therefore, a mean film thickness of color filter through which all lights pass during the time in which they travel the associated distance after they are inputted to the inside until they are outputted to the outside becomes nearly equal to that could be observed in the transmissive section T.

  • Patent number: 7405785
    Abstract: A color filter substrate C includes an orientation film 56 provided on one surface of another glass substrate 10 and an optical compensation layer 35 provided on the other surface of the glass substrate 10 and formed from a plastic film. The two substrates are disposed such that the orientation films thereof oppose each other, and polarization plates 34 and 5 are disposed on the outer sides of the two substrates, and a liquid crystal layer 4 having a positive refractive index anisotropy is provided between the orientation films 23. The optical compensation layer 35 has a negative one axial refractive index anisotropy and can cancel a retardation produced in the liquid crystal layer 4 thereby to suppress white floating of a black display portion.

  • Publication number: 20060274249
    Abstract: An active matrix liquid crystal display panel by which a good display characteristic can be obtained without suffering from gradation reversal over a wide visibility angle range. A liquid crystal layer 4 is formed such that the thickness-thereof varies in accordance with transmission wavelengths of color layers 6, 7 and 8 so that a very good display which does not exhibit any coloring in whichever direction it is viewed may be obtained. An active matrix substrate A includes a plurality of opposing electrodes 2, a plurality of pixel electrodes 3 parallel to the opposing electrodes 2, a thin film transistor, and an orientation film 23 all formed on a glass substrate 10. A color filter substrate C includes an orientation film 56 provided on one surface of another glass substrate 10 and an optical compensation layer 35 provided on the other surface of the glass substrate 10 and formed from a plastic film.

  • Patent number: 7105368
    Abstract: A LCD device prevents the color irregularities (e.g., the red-color irregularity) from occurring without complicating the fabrication processes of a color filter. Switching elements are formed on a first substrate. A color layer is formed on a second substrate. The color layer has a red sublayer, a green sublayer, and a blue sublayer. A liquid-crystal layer is located between the first and second substrates. The second substrate includes no electrodes formed in such a way as to be located on a side nearer to the liquid-crystal layer with respect to the color layer. A green-coloring composition forming the green sublayer contains a pigment having a copper phthalocyanine skeleton. A ratio in weight of the pigment with respect to the green-coloring composition is equal to or less than approximately 27%.
