  • Patent number: 9097948
    Abstract: At a corner of a TFT substrate in which sealants are coated overlapping each other, a phenomenon that the width of the sealants is increased and protrude to the display region is prevented. An organic passivation film is formed as far as the outside of the display region. A groove-like organic passivation film removed portion is formed surrounding the display region. Since the sealants are coated overlapping each other at the corner, when a TFT substrate and a counter substrate are superposed at a predetermined gap, the width of the groove-like organic passivation film removed portion is made larger at the corner than the side in order to prevent the sealant from extending. Since an excessive sealant is absorbed in the groove-like organic passivation film removing portion of a larger width at the corner, the sealant can be prevented from protruding to the inside of the display region.

    Abstract: Reduction in the reliability of a seal portion is prevented. The reduction is caused by a light shielding portion formed on the seal portion of a TFT substrate to hamper curing an ultraviolet curable sealing material. A sealing material has a two-layer structure of an ultraviolet curable sealing material that is an inner sealing material and a thermosetting and ultraviolet curable sealing material or a thermosetting sealing material that is an outer sealing material. A light shielding portion is formed on a TFT substrate under the outer sealing material, and is not formed on the TFT substrate under the inner sealing material. When ultraviolet rays are applied from the TFT substrate side, the inner sealing material is cured in a short time. The outer sealing material is then cured by heating. Thus, the overall seal portion can be sufficiently cured, and a highly reliable seal portion can be formed.

  • Patent number: 8994908
    Abstract: In a liquid crystal display device, a light shielding film, a color filter, an overcoat film, and an alignment film are formed in this order on a counter substrate. However, the alignment film is not formed in a seal portion. When the alignment film is subjected to photo-alignment with ultraviolet radiation, a portion of the overcoat film not covered with the alignment film is degraded by ultraviolet radiation. In order to prevent moisture penetrating from the degraded overcoat film from reaching the light shielding film to thereby alter the light shielding film and from causing the peeling of the light shielding film, the color filter is disposed below the overcoat film to block the moisture.
