摘要： An image retention phenomenon and black unevenness generated after long-time operation in the liquid crystal device are prevented. By using a material having a polyamide acid ester as a precursor less likely to adsorb impurities on a boundary for an alignment film and a material having a dielectric constant anisotropy Δ∈ of 5 or less for liquid crystals, adsorption of an antioxidant dispersed in the liquid crystals is suppressed to prevent oxidation of the liquid crystals. The extent that impurities are intruded into the liquid crystals is reduced by restricting the dielectric constant anisotropy Δ∈ of the liquid crystals to 5 or less, thereby capable of preventing the image retention phenomenon and the black unevenness.

And an opposite substrate retains a columnar spacer for ensuring a cell gap, and a columnar projection for misalignment prevention formed at a position corresponding to a position of the contact hole. Accordingly, misalignment between the TFT substrate and the opposite substrate is suppressed, occurrence of uneven brightness due to misalignment between pixel regions and a bright spot caused by shaving of an orientation film is prevented, and a favorable image is obtained.

摘要： A liquid crystal display device includes: a liquid crystal layer which contains a liquid crystal composition; a pair of substrates opposed to each other across the liquid crystal layer; alignment layers placed on liquid crystal layer sides of the pair of substrates, respectively; and polarization plates placed on opposite sides from the liquid crystal layer sides, respectively. The pair of substrates includes a thin-film transistor substrate including a thin-film transistor for controlling molecule alignment of the liquid crystal composition, and a color filter substrate including a color layer containing pixels of different colors. A blue pixel, which is one of the pixels of different colors, is larger in area than any of the pixels of other colors. A loss of light in a short-wavelength range is thus reduced.

摘要： In the step of curing a resin for bonding a TFT substrate and a counter substrate each having an alignment film that has been optically aligned by using UV-light, damage to the alignment film due to the UV-light can be prevented without using a light shielding mask.A UV-light absorption layer is formed between each black matrix on the counter substrate. The TFT and counter substrates are sealed at their periphery by a resin that is cured by UV-light radiated from the counter substrate side. Since the absorption layer has a high absorbability to UV-light at a wavelength of 300 nm or less that degrades the alignment film, damage to the alignment film due to the UV-light for curing the resin can be prevented. Thus, provision of a light shielding mask for shielding the UV-light for the display region can be saved.

摘要： An IPS liquid crystal display device intended to prevent generation of second image sticking after generation of initial DC image sticking.An alignment film has a two-layer structure comprising an upper alignment film and a lower alignment film. The upper alignment film is an optical alignment film formed of a polyamide acid ester as a precursor. The lower alignment film has a lower resistance value than the upper alignment film and also has a low photoconductive property. The lower alignment film is formed not using, as a precursor, a polyamide acid using PMDA as the starting material but using, as a precursor, the polyamide acid containing a sulfonic acid group or a carboxylic group, whereby the difference of the resistance between portions undergoing or not undergoing light irradiation in the pixel is decreased and generation of second image sticking can be prevented.
