Abstract

The invention provides a liquid crystal display device and a manufacturing method thereof. The device comprises a first substrate, a second substrate, projections and spacers, wherein, the first substrate is provided with a plurality of spacers; the second substrate is provided with a plurality of projections; the projections correspond to and are contacted with parts of the spacers on the first substrate. The surface of the projection is a smooth buffer surface. The smooth buffer surface of the projection can effectively prevent the occurrence of push mura or touch mura.

Description

【Technical field】 [0001] The present invention relates to a liquid crystal display device and a manufacturing method thereof, in particular to a liquid crystal display device having a protrusion structure corresponding to spacers and a manufacturing method thereof. 【Background technique】 [0002] In recent years, due to the rapid development of optoelectronic technology, liquid crystal displays (Liquid Crystal Displays, LCDs) with the characteristics of small size, light weight, and good display effect are more and more favored by consumers. [0003] figure 1 It is a schematic diagram of an existing liquid crystal display panel (the corresponding reference is Chinese patent application: CN 1991488). figure 2 yes figure 1 A schematic diagram of the liquid crystal display panel when it is subjected to a lateral force. Such as figure 1 As shown, the liquid crystal display panel 100 includes an upper substrate 101 , a lower substrate 102 and a liquid crystal layer (not show...
