Problems solved by technology

However, when the arrangement density of the photo-spacers increases, the elasticity of the liquid crystal layer itself decreases, which eventually leads to the formation of air bubbles or uneven gaps due to gravity
On the other hand, when the density of the arrangement decreases, the pressure resistance in the case where the liquid crystal layer is applied with pressure decreases

Abstract

A liquid crystal display device is provided, suppressing formation of defect such as bubbles within a liquid crystal layer, to enhance yield. The liquid crystal display device includes: a first substrate and a second substrate facing each other; a liquid crystal layer provided between the first substrate and the second substrate to configure a plurality of pixels; a plurality of color filters formed on the first substrate, each of the plurality of color filters being divided into individual filter elements corresponding to the pixels, respectively; main spacers provided on one color kind of color filter of the plurality of color filters to control a gap between the first substrate and the second substrate; and sub spacers, which are lower than the main spacers in height, provided on the same color kind of color filter as the one color kind of color filter where the main spacers are provided thereon.

Description

technical field [0001] The present invention relates to a liquid crystal display device capable of displaying images in color. Background technique [0002] Recently, liquid crystal display devices employing a VA (Vertical Alignment) mode are used as display monitors such as liquid crystal televisions, notebook computers, car navigation systems, and the like. A liquid crystal display device includes a liquid crystal layer disposed between a driving substrate for driving pixels and an opposite substrate on which color filters and the like are formed and performing image display according to an applied voltage. [0003] The liquid crystal layer is formed by injecting a liquid crystal material into a space between a driving substrate and an opposite substrate. The method of injecting liquid crystals has been changed from the immersion method to the ODF (Drop In) method. In the immersion method, a driving substrate and an opposite substrate are bonded together by using a seali...
