  • Patent number: 10890808
    Abstract: A cell assembly, including a first substrate and a second substrate. The first substrate includes: a color resist layer and a first passivation layer. The first support protrudes from the color resist layer. The first passivation layer covers the color resist layer. The first passivation layer and the first support together form a first support assembly, and the first support assembly is in surface contact with the second substrate. Compared with the use of the silicon ball and the gold ball independent of the first substrate to support the second substrate, the present construction is much stable and has better support effect, thereby realizing the uniform thickness of the peripheral region of the cell.
