Benefits of technology

[0007]Accordingly, the present invention is directed to provide a liquid crystal display (LCD) panel and a fabricating method thereof, wherein the LCD panel has stronger anchoring energy and better performance in surface gliding and voltage-transmittance (V-T) curve shift, accordingly, the photo-electronic properties of the LCD are improved, for example, imaging sticking is reduced.
[0010]According to the present invention, the anchoring energy of a LCD panel can be increased through a liquid crystal polymer layer. Besides, a liquid crystal polymer layer may also be formed on a film which has been performed with an alignment process to serve as an alignment assistant layer and so as to improve the alignment properties of liquid crystal molecules and to resolve the problem of insufficient anchoring energy after alignment. Accordingly, surface gliding and V-T curve shift can be reduced and the display quality of the LCD panel can be improved, for example, imaging sticking can be reduced.

Problems solved by technology

Even the problems such as static produced by contact rubbing alignment and particle contamination can be resolved by non-contact alignment process, the problem of insufficient anchoring energy of the alignment surface may be caused therein.
Insufficient anchoring energy of an alignment surface may result in bad display quality of the LCD panel.

first embodiment

[0019]FIGS. 1A˜1E are cross-sectional views illustrating the fabricating flow of a liquid crystal display (LCD) panel according to the first embodiment of the present invention. Referring to FIG. 1A, the first substrate 101 is composed of the substrate 100 and a film layer 102 formed on the substrate 100, and the second substrate 201 is composed of the substrate 200 and a film layer 202 formed on the substrate 200. The substrates 100 and 200 may be glass substrates, silicon substrates, flexible plastic substrates, or any existing substrate which can be used for fabricating display panel. If the display panel in the present invention is a passive matrix display panel, then film layer 102 and film layer 202 may be respectively an electrode layer. If the display panel in the present invention is an active matrix display panel, then film layer 102 may be an active matrix device layer, and film layer 202 may be a common electrode layer. The material of the electrode layer may be organic ...

second embodiment

[0028]FIGS. 2A-2E are cross-sectional views illustrating the fabricating flow of a LCD panel according to the second embodiment of the present invention. Referring to FIG. 2A, a first substrate 101 and a second substrate 201 are provided first. The composition and material of the first substrate 101 and the second substrate 201 are as those described in the first embodiment, therefore will not be described herein. Next, a first alignment material layer 120 and a second alignment material layer 220 are respectively formed on the surfaces of the first substrate 101 and the second substrate 201. The first and the second alignment material layers 120 and 220 may be an organic alignment material or an inorganic alignment material. In an embodiment, the organic alignment material includes poly vinyl alcohol, polyimide, polyamic acid, azo-benzene, poly vinyl cinnamate, compound containing coumarin group, compound containing chalcone group, or other existing organic alignment material. In a...

Abstract

A liquid crystal display (LCD) panel and a fabricating method thereof are described. First, a first substrate and a second substrate are provided. A liquid crystal monomer layer is then formed on the surface of at least one of the first and second substrates. Next, a curing step is performed to the liquid crystal monomer layer to induce a polymerization reaction, so as to form a liquid crystal polymer layer. Thereafter, the first and second substrates are assembled and a liquid crystal layer is filled between the first and second substrates.
