Abstract

The invention discloses a liquid crystal display device and a preparation method thereof. The device comprises an upper substrate, a lower substrate corresponding to the upper substrate, a display area, a frame adhesive and a polymer ring, wherein the display area is arranged between the upper substrate and the lower substrate and filled with liquid crystal, and the frame adhesive is arranged on the outer edge of the liquid crystal display device. The polymer ring surrounds the display area, and the frame adhesive is arranged around the outer edge of the polymer ring; the upper end and the lower end of the polymer ring are connected with the upper substrate and the lower substrate respectively. Because the periphery of the display area is surrounded by the polymer ring, and the upper end and the lower end of the polymer ring are connected with the upper substrate and the lower substrate, the liquid crystal is completely isolated from the frame adhesive, and thus it is avoided that the liquid crystal is polluted.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a liquid crystal display device and a preparation method thereof. Background technique [0002] As we all know, LCD is a liquid crystal display, and the liquid crystal material plays a very important role as a light valve. But there will be more or less the problem of liquid crystal being polluted. The traditional vacuum infusion process of LCD production is to first cure the frame glue and then pour the liquid crystal. Although the frame glue has been cured, there will still be contamination and analysis of the liquid crystal. The ODF process is to bond the substrate coated with frame glue and another substrate dripped with liquid crystal and then cure the frame glue. If the frame glue cannot be cured in a short time, the uncured frame glue will easily mix with the liquid crystal material. The contact will cause the liquid crystal to be polluted, and the cured f...
