In-plane switching mode liquid crystal display device

摘要

A liquid crystal display device includes first and second substrates and a liquid crystal layer interposed therebetween; a gate line, a data line and a common line over the first substrate in the display area; a thin film transistor connected to the gate line and the data line; a color filter layer over the thin film transistor; a first passivation layer over the color filter layer; an auxiliary common line, inner common electrodes and pixel electrodes over the first passivation layer, wherein the auxiliary common line includes a vertical portion and a horizontal portion, the inner common electrodes extend from the horizontal portion, and the pixel electrodes alternate the inner common electrodes; a light blocking pattern in the non-display area, wherein the light blocking pattern includes the same materials as the color filter layer.

1. A liquid crystal display device, comprising:
first and second substrates facing each other, wherein a display area and a non-display area are defined on the first and second substrates, and a liquid crystal layer is interposed between the first and second substrates; a gate line, a data line and a common line over an inner surface of the first substrate in the display area, wherein the gate line and the data line intersect each other to define a pixel region, and the common line is parallel to the gate line; a thin film transistor at the pixel region and connected to the gate line and the data line; a color filter layer over the thin film transistor all over the display area; a first passivation layer of photo acryl over the color filter layer; an auxiliary common line, inner common electrodes and pixel electrodes over the first passivation layer, wherein the auxiliary common line includes a vertical portion overlapping the data line and a horizontal portion overlapping the gate line and the common line and has a lattice structure, the inner common electrodes extend from the horizontal portion in the pixel region and have a bar shape, and the pixel electrodes alternate the inner common electrodes and have a bar shape, the auxiliary common line forming a light shielding pattern in a periphery of the pixel region and interconnecting a plurality of the inner common electrodes of an individual pixel region; outer common electrodes for the individual pixel region formed on the first substrate, the outer common electrodes connected to the auxiliary common line in a region where the vertical and horizontal portions of the auxiliary common line intersect; and a light blocking pattern in the non-display area and surrounding the display area, wherein the light blocking pattern includes the same materials as the color filter layer.
