摘要： A VA-mode liquid crystal display device which includes a pair of alignment sustaining layers 34a and 34b formed by a photopolymerized material on surfaces of a pair of vertical alignment films 32a and 32b which are closer to a liquid crystal layer, and a cruciform opening 22a provided only in a counter electrode. When a predetermined voltage is applied across the liquid crystal layer, four liquid crystal domains are formed such that the azimuths of the directors of the respective liquid crystal domains are different from one another and form an angle of about 45′ relative to the polarization axes of a pair of polarizing plates. When no voltage is applied across the liquid crystal layer, the pretilt azimuths of liquid crystal molecules included in regions respectively corresponding to the four liquid crystal domains are regulated by the alignment sustaining layers 34a and 34b.

摘要： An active matrix substrate includes base substrate, gate lines, data lines, thin-film transistors and pixel electrodes. The gate lines are formed on the base substrate. The data lines are formed over the gate lines. Each of the data lines crosses all of the gate lines with an insulating film interposed therebetween. The thin-film transistors are formed over the base substrate. Each of the thin-film transistors is associated with one of the gate lines and operates responsive to a signal on the associated gate line. Each of the pixel electrodes is associated with one of the data lines and one of the thin-film transistors and is electrically connectable to the associated data line by way of the associated thin-film transistor. Each of the pixel electrodes and the associated thin-film transistor are connected together by way of a conductive member. Each of the pixel electrodes crosses one of the gate lines, while the conductive member for the pixel electrode crosses another one of the gate lines that is adjacent to the former gate line.

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.
