Problems solved by technology

Therefore, as can be seen from FIG. 3, when the liquid crystal filled by the liquid crystal dropping method moves along the gravitational direction (arrow direction), as the liquid crystal flows to the bottom, the substrates 10 and 20 are both bent outward, so that the cell gap at the bottom becomes smaller. wider than the upper cell gap, which results in image display quality degradation

Abstract

An LCD capable of preventing a gravity failure is provided. The LCD makes substrates constituting an LC panel not easily warped. The LCD includes a first substrate and a second substrate facing each other, a liquid crystal layer interposed between the first substrate and the second substrate, and a gravity failure-prevention structure, for preventing at least one of the first and second substrates from warping, formed on the at least one of the first substrate and the second substrate.

Description

technical field [0001] The present invention relates to a liquid crystal display, and more particularly, to a liquid crystal display capable of improving gravity failure. Background technique [0002] Among ultra-thin flat panel displays with a thickness of only a few centimeters, a liquid crystal display device (LCD) has the advantage of low operating voltage, thus low power consumption and portability. Therefore, LCDs can be widely used in many applications such as notebook computers, monitors, spacecraft and aircraft instruments. [0003] Hereinafter, a related art LCD will be described in detail with reference to the accompanying drawings. [0004] FIG. 1 is an exploded perspective view of a related art LCD, and FIG. 2 is a schematic sectional view of the related art LCD. [0005] Referring to FIG. 1, the LCD includes a lower substrate 10 and an upper substrate 20 opposed to each other and spaced apart from each other by a predetermined interval, and a liquid crystal l...
