Problems solved by technology

[0013] As a result, conventional LCD panels have defects in image quality due to the non-uniformity of the cell gap, whereby the image becomes brighter or darker closer to the sides of the LCD panel relative to the center of the LCD panel
In addition, the larger the liquid crystal panel, the more severe the defect in image quality due to the non-uniformity of the cell gap

Embodiment Construction

[0031] Hereinafter, an embodiment of the present invention will be described with reference to FIGS. 3 to 6 .

[0032] FIG. 3 is a cross-sectional view of a liquid crystal panel using a columnar spacer, and FIG. 4 is a view showing a partitioned area of ​​the liquid crystal panel forming the columnar spacer shown in FIG. 3 .

[0033] The liquid crystal panel shown in FIG. 3 includes an upper substrate 22 and a lower substrate 20 assembled by a sealing line 30, and the liquid crystal is placed between the upper and lower substrates. The liquid crystal panel also includes a plurality of column spacers, shown as 24, 26, 28 Three columnar spacers are formed between the upper base 22 and the lower base 20 .

[0034] The upper substrate 22 includes a black matrix and color filters formed on an insulating substrate. The black matrix formed in a matrix shape prevents light leakage and divides the liquid crystal cell area into sub-pixel units. The color filters formed in the liquid c...

Abstract

A liquid crystal panel and a manufacturing method thereof which can ensure the uniformity of a cell gap. The liquid crystal panel includes first and second substrates assembled by a seal line with a liquid crystal interposed therebetween, and column spacers of which tilt angles are differently formed according to their locations, thereby maintaining a cell gap constant between the first and second substrates.

Description

[0001] This application claims the benefit of Korean Patent Application No. 10-2005-0084982 filed with the Korean Intellectual Property Office on September 13, 2005, the disclosure of which is hereby incorporated by reference in its entirety. technical field [0002] The present disclosure relates to a liquid crystal display panel, and more particularly, to a liquid crystal display panel capable of preventing cell gaps from becoming uneven, and a manufacturing method for such a liquid crystal display panel. Background technique [0003] The liquid crystal display device displays images by adjusting light transmittance of liquid crystals having dielectric anisotropy using an electric field. To achieve this, a liquid crystal display device includes a liquid crystal display panel (hereinafter, referred to as a liquid crystal panel) for displaying images through a matrix of liquid crystal cells and a driving circuit for driving th...
