  • Patent number: 7652739
    Abstract: A matrix-addressed type liquid crystal display apparatus having switching devices such as TFTs is provided, featuring that an increased effective voltage can be applied without causing hysteresis in V-T characteristics. Namely, by substantially increasing a value of an applicable voltage in excess of which a display defect starts to appear, a high numerical aperture and a high contrast ratio have been achieved at the same time. In the LCD apparatus of the present invention, a gap between adjacent reverse tilt domains each formed in a portion of a pixel which is arranged corresponding to an arbitrary pixel electrode becomes broader than a minimum gap between adjacent pixel electrodes corresponding thereto, or a thickness of a liquid crystal cell in the portion between adjacent reverse tilt domains is set thinner than a thickness of a liquid crystal cell in the portion of the pixel.

  • Patent number: 6788372
    Abstract: A liquid crystal panel of any type is improved in display quality by adjusting a gap size with high accuracy and uniformity, a liquid crystal display and a liquid crystal projector adopting the liquid crystal panel of the present invention. A manufacturing method for such a liquid crystal panel at a low cost with high productivity is also disclosed. The liquid crystal panel is composed generally of first and second substrates opposed to each other with a given gap defined therebetween and a liquid crystal layer filling this given gap. One surface of the first substrate adjacent to the liquid crystal layer is formed with a planarizing film having a flat surface on the liquid crystal layer side. A plurality of pixels in the form of a matrix are formed on the flat surface of the planarizing film, and a light shielding region is formed between any adjacent ones of the pixels by a black matrix and a signal line.

  • Patent number: 6573967
    Abstract: A liquid crystal display apparatus has a drive substrate and a facing electrode substrate superimposed and joined each other via spacers and seal materials, wherein the drive substrate carries drive devices for driving liquid crystal material, the facing electrode substrate carries facing electrodes facing to the drive devices. Liquid crystal material is injected between the drive substrate and the facing electrode substrate. The seal materials include an outer seal formed along outer periphery of the drive substrate and the facing electrode substrate and inner seals formed inside of the outer seal, and a space between the out side part of an effective picture element area having drive devices and an inside portion of the outer seal facing to the effective picture element area or an inside portion of the inner seal can be formed in approximately uniform.
