Problems solved by technology

However, if Figure 3B and 3C As shown in , when the sealant is applied with a dispenser that deviates from the first position P01 and is located at the second position P02 or the third position P03, a deviation DV due to the spread of the sealant may occur during the bonding process, Thus the sealant 80 may deviate from the desired position
[0017] In consideration of this deviation DV, the area where the sealant 80 is to be formed increases by the same area as the deviation DV, so that the non-display region NDR may expand.
In other words, it will hinder the realization of the narrow border required by LCD

Abstract

The invention provides a liquid crystal display (LCD) device, which comprises: first and second substrates facing each other, the first and second substrates each have a display region (DR), a non-display region (NDR) and a seal pattern area arranged in the non-display area; a protective layer located on the first substrate and having a first seal pattern groove in the seal pattern area; a first seal pattern groove located on the second substrate and respectively arranged at both ends of the first seal pattern groove and a second baffle, the first and second baffles are configured to form a second seal pattern groove corresponding to the position of the first seal pattern groove; a pixel electrode located on the first substrate; a pixel electrode located on the first and second substrate a common electrode on one of them; a liquid crystal layer located between the first and second substrates; and a seal pattern with one end inserted into the first seal pattern groove and the other end inserted into the second seal pattern groove.

Description

technical field [0001] The present invention relates to a display device, and more particularly, to an LCD device in which a guide pattern for a seal pattern is formed to reduce a design margin in forming the seal pattern so that a narrow bezel can be realized. Background technique [0002] In recent years, with the advent of the information society, display devices configured to process and display a large amount of information have been rapidly developed. Among these display devices, LCD devices have recently been developed as high-efficiency flat panel display (FPD) devices, which are made slim and have low power consumption to replace conventional cathode ray tubes (CRTs). [0003] Among LCD devices, an active matrix type LCD including an array substrate has attracted a lot of attention because the active matrix type LCD has a high resolution and can express dynamic images well, and among the array substrates, a thin film transistor (TFT) is used for As a switching devi...
