Embodiment Construction

[0032] figure 1 It is a structural schematic diagram of the first embodiment of the columnar spacer of the present invention. Such as figure 1 As shown, the main structure of the cylindrical spacer in this embodiment is a cylindrical body 1, and the cylindrical body 1 may be a straight cylinder, preferably a tapered cylinder. The cylindrical body 1 has a bottom end 2 and a top end 3. The bottom end 2 with a larger diameter is used to connect with a substrate (such as a color filter substrate) of the liquid crystal display panel, and the top end 3 with a smaller diameter is used to support the other side of the liquid crystal display panel. Substrates (such as array substrates) to keep the distance between the two substrates of the liquid crystal display panel; where the central part of the top 3 is provided with a columnar first protrusion 31, and the peripheral part of the top 3 is provided with a second protrusion 32 , and the height of the first raised portion 31 is gre...

Abstract

The invention relates to a cylindrical spacer which comprises a cylindrical part that has a base end connected with a substrate of liquid crystal display panel and a top end supporting the other substrate of liquid crystal display panel. The top end of cylindrical part is a projection structure which is high at central part and low at external part, or a concave structure which is low at central part and high at external part. The invention also relates to a liquid crystal display panel which comprises a color film substrate and an array substrate, and a cylindrical spacer which has a base end connected with the color film substrate and a top end supporting the array substrate. The top end of cylindrical spacer is a projection structure or a concave structure which has larger preset deformation force and larger deformation allowance. The liquid crystal display panel according to the invention simultaneously increases the allowed filling high limit of liquid crystal and allowed filling lower limit of liquid crystal, can provide a liquid crystal layer allowance with larger range, reduce the technical requirement for the box, and increases the picture quality of liquid crystal display.

Description

technical field [0001] The invention relates to a liquid crystal display, in particular to a columnar spacer and a liquid crystal display panel using the columnar spacer. Background technique [0002] Liquid Crystal Display (LCD for short) has the characteristics of small size, low power consumption, and no radiation. It has developed rapidly in the past ten years, and has made great progress in terms of screen size and display quality. Currently, LCD development focuses on improving image quality and reducing production costs. The existing liquid crystal display includes two substrates: a color filter substrate (CF substrate) and an array substrate (Array substrate), and a liquid crystal layer composed of liquid crystal material is arranged between the two substrates. In order to control the stable uniformity of the thickness of the liquid crystal layer, spacers are arranged between the two substrates in the prior art. There are two methods for setting spacers, one is to ...
