    Abstract: A liquid crystal panel and manufacturing method thereof are provided. The liquid crystal panel includes: an array substrate provided with thin film transistors; a color filter substrate provided with primary photo-spacers and secondary photo-spacers. The primary photo-spacers correspond to the thin film transistors. Stage differences between the secondary photo-spacers and the primary photo-spacers decrease from the center of the panel to the boundaries thereof. Liquid crystal is filled within space between two substrates, which are then sealed. By applying a design that utilizes stage differences between the primary and secondary photo-spacers being different, optical performance decrease caused by non-uniform box thickness in different regions is prevented.

  • Patent number: 9671651
    Abstract: A display panel includes a first substrate and a second substrate disposed separately; a sealant disposed between the first substrate and the second substrate; and at least one color resist layer disposed between the first substrate and the second substrate; wherein, the at least one color resist layer and the sealant are disposed in an alternate arrangement, and are disposed between the first substrate and the second substrate in order to support the first substrate and the second substrate. A display device is also disclosed. Through replacing the spacers in the sealant with the color resist layer to support the first substrate and the second substrate, a display uneven phenomenon near the sealant of a narrow frame display panel is solved. In addition, because the color resist layer replaces the spacer, the cost of the spacer is saved so as to reduce the design cost.
