摘要： An alignment-divided vertical alignment liquid crystal display device permitting improvement in response characteristic while suppressing reduction in contrast ratio is provided. The device has a plurality of pixels each having a first electrode, a second electrode facing the first electrode, and a vertical alignment liquid crystal layer placed between the first and second electrodes. Ribs are placed in a surface portion of the liquid crystal layer close to the first electrode and/or a surface portion thereof close to the second electrode. The ribs have slope side faces put in contact with the liquid crystal layer, and satisfy the relationships RL/PS≧0.05 (μm−1) and RS/PS≦0.05 where RS is the product (RL·RH) of the total length RL of the side faces in a pixel as viewed from the normal to the liquid crystal layer and the height RH of the ribs, and PS is the pixel area.

摘要： A liquid crystal display device includes a plurality of picture element regions each including a first electrode provided on one side of a first substrate that is closer to a liquid crystal layer and a second electrode provided on a second substrate so as to oppose the first electrode via the liquid crystal layer therebetween. The first electrode includes, in each picture element region, a solid portion including a plurality of unit solid portions, whereby the liquid crystal layer takes a substantially vertical alignment in the absence of an applied voltage between the first electrode and the second electrode, and forms a liquid crystal domain taking a radially-inclined orientation in a region corresponding to each unit solid portion of the first electrode by an inclined electric field produced around the unit solid portion in response to a voltage applied between the first electrode and the second electrode. Each unit solid portion includes four acute angle corner portions that are pointing respectively in upward, downward, leftward and rightward directions of a display plane.

摘要： A liquid crystal display device according to the present invention includes: a vertical alignment liquid crystal layer; first and second electrodes arranged on one surface of first and second substrates to face the liquid crystal layer; and first and second alignment films arranged on the first and second electrodes, respectively, in contact with the liquid crystal layer. The first alignment film has been subjected to an optical alignment treatment by obliquely irradiating a first alignment film material, having a photosensitive wavelength within the wavelength range of 250 nm to 380 nm, with light including the photosensitive wavelength. The device further includes: a metal layer arranged between the first alignment film and the first substrate; and a first resin layer arranged between the metal layer and the first alignment film. The first resin layer has an optical property that attenuates the intensity of light, which has been incident on the first resin layer and then reflected from the metal layer, to 60% or less at the photosensitive wavelength.
