Embodiment Construction

[0031] Reference will now be made in detail to exemplary embodiments of the present invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.

[0032] Figure 2A is a plan view showing an upper substrate of a liquid crystal display according to a first embodiment of the present invention, Figure 2B is the same as Figure 2A A cross-sectional view of the liquid crystal display corresponding to the middle line A-A, and Figure 2C is the same as Figure 2A The cross-sectional view of the liquid crystal display corresponding to the middle line B-B.

[0033] Such as Figure 2A to Figure 2C As shown, the liquid crystal display according to the first embodiment of the present invention includes an upper substrate 100 , a lower substrate 200 , column spacers 310 and 320 , and a liquid crystal layer 400 .

[0034] A black matrix 110 is formed on...

Abstract

A liquid crystal display device is discussed, which includes a first substrate and a second substrate, which face each other; a liquid crystal layer formed between the first substrate and the second substrate; and a column spacer formed between the first substrate and the second substrate, wherein the column spacer is formed within a light-shielding region on the first substrate or the second substrate, and a width of the light-shielding region in the periphery of the column spacer is greater than that of the light-shielding region where the column spacer is not formed. Since the width of the light-shielding region in the periphery of the column spacer is greater than that of the light-shielding region where the column spacer is not formed, even though an alignment film is damaged by the column spacer, light leakage can be prevented from occurring at the damaged portion.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of Korean Patent Application No. 10-2010-0070461 filed Jul. 21, 2010, which is incorporated by reference for all purposes as if fully disclosed herein. technical field [0003] The present invention relates to a liquid crystal display, and more particularly, to a liquid crystal display capable of preventing light leakage from occurring. Background technique [0004] Due to advantages of low power consumption and portability based on a low driving voltage, liquid crystal displays are widely used in various fields such as notebook computers, monitors, spaceships, and aircrafts. [0005] A liquid crystal display includes a lower substrate, an upper substrate, and a liquid crystal layer between the lower substrate and the upper substrate. In the liquid crystal display, the alignment state of the liquid crystal molecules is controlled according to whether an electric field is applied to ...
