  • Patent number: 10578924
    Abstract: Various layer separation states are generated by the combination of a polyamide acid ester and a polyamide acid and a long residual image characteristic cannot be further improved merely by combining them. A liquid crystal display device comprises a substrate, a liquid crystal layer, and an orientation film placed between the substrate and the liquid crystal layer. The orientation film comprises a polyimide precursor having two or more components. In the polyimide precursor, an octanol-water partition coefficient is defined as log P and the difference in log P (? log P) between the two components having most distant log Ps is set so as to fall within a prescribed range.

  • Patent number: 10571808
    Abstract: Provided is a polarized light irradiation apparatus for exposure of a photosensitive film on a substrate. The polarized light irradiation apparatus includes: a transport stage including a stage surface that is reciprocated in a state where the substrate is placed on the stage surface and a heating mechanism that heats the substrate placed on the stage surface; and a polarized light irradiation mechanism irradiates the stage surface moving in an exposure region with polarized light. The transport stage moves in the exposure region at a first average speed in a forward path while heating the substrate by the heating mechanism. The transport stage moves in the exposure region at a second average speed lower than the first average speed in a backward path while heating the substrate by the heating mechanism.

  • Patent number: 10534225
    Abstract: A liquid crystal display device includes a TFT substrate having a first alignment film and an opposing substrate having a second alignment film with liquid crystals sandwiched therebetween. One of the first and second alignment films, comprises a first polyimide produced via polyamide acid ester containing cyclobutane as a precursor and a second polyimide produced via polyamide acid as a precursor. The polyamide acid has a higher polarity than that of the polyamide acid ester. The one of the first and second alignment films is responsive to photo-alignment. A first side of the one of the first and second alignment films is adjacent to the liquid crystals, and a second side thereof is closer to one of the TFT substrate and the counter substrate than the first side. The first side contains more of the first polyimide and less of the second polyimide than the second side.
