Provided is a method of manufacturing new liquid crystal display device according to an embodiment of the present invention. Firstly, an alignment film is formed on a substrate. The alignment film is divided into a first alignment film formed using, as a precursor, liquid-state polyimide that contains a photodecomposition substance and a second alignment film formed using, as a precursor, a polyamic acid that does not contain a photodecomposition substance. UV light is irradiated to the alignment film, and decomposed substances formed by irradiation of the UV light is removed by an at least two-step removing process. By the method of manufacturing a liquid crystal display device according to the exemplary embodiment of the present disclosure, bright spots are minimized in pixels and a brightness of black is lowered, so that a liquid crystal display device with a high contrast ratio can be realized.

Liquid crystal display device and method of manufacturing the same

An alignment film for liquid crystal display device includes a first portion positioned towards to the liquid crystal layer and a second portion positioned away from the liquid crystal layer. The first portion provides improved anchoring force while the second portion exhibits a lower volume resistance than the first portion. Thus, AC image sticking and DC image sticking can be minimized at the same time.

A stereoscopic image display device comprises a liquid crystal panel alternately displaying a first image and a second image, the first and second images being changed at first transition durations every frame, a polarization control panel disposed on the liquid crystal panel and changing polarization states at second transition durations, polarization glasses enabling the displayed first and second images to be viewed via the polarization control panel, and a backlight unit providing light to the liquid crystal panel and having black durations where the light is not provided to the liquid crystal panel.

The present disclosure relates to a three-dimensional image system. The present disclosure suggests a three dimensional image system comprising: a display device configured to suggest a left image and a right image alternately; a liquid crystal shutter having a liquid crystal layer and configured to switch between a &#x3bb;/2 phase retardation state and a 0 phase retardation state; polarized glasses including a right glass window having a first polarization axis and a left glass window having a second polarization axis. According to the present disclosure, the left image and the right image can be exactly recognized by the left eye and the right eye, respectively, without any cross-talk problem.
