Abstract

A liquid crystal panel includes an array substrate and a color filter substrate that is arranged opposite to the array substrate and a liquid crystal layer interposed between the array substrate and the color filter substrate, and an enclosure resin frame surrounding the liquid crystal layer. A support is arranged in the liquid crystal layer of the liquid crystal panel and the support supports between the array substrate and the color filter substrate. The support includes a first support layer and a second support layer connected to the first support layer. The first support layer is made of a thermally deformable material. The second support layer is made of a flexible material of elastic restorability. A liquid crystal displaying device is also provided.
