Abstract

Disclosed is a liquid crystal display device including first and second substrates, each of the substrates having a display area and a non-display area; a liquid crystal layer between the first and second substrates; a column spacer in each of the display area and the non-display area on the first substrate; and a thin film layer stack in each of the display area and the non-display area on the second substrate, wherein a distance from the second substrate to an end of the thin film layer stack in the display area is identical to a distance from the second substrate to an end of the thin filmlayer stack in the non-display area.

Description

[0001] This application is a divisional application of the original patent application number 201510891126.7 (application date: December 7, 2015, invention name: liquid crystal display device). technical field [0002] Embodiments of the present invention relate to a liquid crystal display device, and more particularly, to a columnar spacer for maintaining a cell gap of the liquid crystal display device. Background technique [0003] Liquid crystal display (LCD) devices are widely used in various fields of notebook computers, monitors, spaceships, airplanes, etc. due to advantages such as good portability and low power consumption at low operating voltage. [0004] The LCD device includes: a lower substrate on which thin film transistors are formed; an upper substrate on which color filters are formed; and a liquid crystal layer formed between the lower and upper substrates. And, a columnar spacer for maintaining a cell gap between the lower substrate and the upper substrate...
