摘要： A normally closed liquid crystal display device using an in-plane switching mode prevented from light leakage caused by spacer beads and having a high contrast ratio can be produced by making a pretilt angle between an alignment control film and liquid crystals 4° or less and controlling a light leakage centering the spacer in 4-divided shapes; or by placing a film provided with a liquid crystal alignment controlling function by irradiation with polarized light between the spacer and a liquid crystal layer, the spacer being present in a pair of substrates.

摘要： Manufacture of a liquid crystal display is disclosed. The liquid crystal display includes a backlight unit, a backlight unit-side polarizing plate, and a liquid crystal cell held by two glass plates, the liquid crystal cell having an electrode, a liquid crystal layer, an alignment layer, and a color filter arranged between the glass plates. The liquid crystal display also includes a transparent front plate arranged at a side of the liquid crystal cell opposite to the backlight unit, a polarizing plate attached to the liquid crystal cell, and a transparent organic medium layer arranged between the front plate and the liquid crystal cell. Since the front plate is provided at the outermost surface of an image display portion, and the transparent organic medium is filled between the front plate and the liquid crystal module, it is possible to achieve an improvement in wear resistance and a reduction in reflectance.

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 a liquid crystal display device, a TFT substrate retains a contact hole that is formed in a passivation film, and is for connecting the TFT and the pixel electrode. 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： 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.
