Embodiment Construction

[0030] Embodiments of the present invention provide an apparatus for manufacturing a liquid crystal display in which bead spacers can be prevented from being provided in two layers.

[0031] Embodiments of the present invention will now be described more fully and in detail with reference to the accompanying drawings. However, this invention may be embodied in different forms and should not be construed as limited to the embodiments set forth herein. figure 1 is a schematic diagram of an apparatus for manufacturing a liquid crystal display according to an exemplary embodiment of the present invention, and figure 2 is an enlarged view of a state where spacer ink is injected into a substrate for providing spacers.

[0032] Such as figure 1 As shown, the manufacturing equipment of a liquid crystal display includes a spacer supply substrate 9, a transfer roller 14, a spacer supply device 15, and a support plate 5 having a display panel 200 mounted thereon.

[0033] The spacer ...

Abstract

A manufacturing apparatus for a liquid crystal display includes a spacer supply substrate in which a plurality of grooves are formed, a transfer roller having a surface to which a plurality of spacers deposited into the grooves are primarily transferred, and a support plate on which a substrate is mounted, wherein the primarily transferred spacers are secondarily transferred onto the substrate as the transfer roller rotates, wherein the diameter of each of the grooves is less than or equal to about seven times the diameter of each of the spacers. The diameter and depth of the groove of the spacer supply substrate and the tilt angle of a sidewall of the groove are controlled to prevent bead spacers from being stacked in two levels.

Description

technical field [0001] The present application relates to a manufacturing equipment of a liquid crystal display. Background technique [0002] Liquid crystal displays are widely used flat panel displays. A liquid crystal display may include two display panels on which field generating electrodes are formed and a liquid crystal layer interposed between the two display panels. A liquid crystal display is a display device that controls light transmittance through a liquid crystal layer by applying a voltage to field generating electrodes to rearrange liquid crystal molecules of the liquid crystal layer. [0003] The upper and lower substrates of the liquid crystal display may be bonded to each other by a sealant that seals a liquid crystal material around the upper and lower substrates of the liquid crystal display. The upper and lower substrates may be separated from each other by spacers to maintain a cell gap therebetween. [0004] Spacers can be classified into spherical...
