Embodiments of the present disclosure relate to a color filter substrate and a manufacturing method thereof, and a display device and a manufacturing method thereof.
A Liquid Crystal Display (LCD) is widely used in a display field. The LCD generally includes a color filter substrate and an array substrate cell-assembled, and liquid crystal and a sealant which are located between the array substrate and the color filter substrate. In the prior art, the color filter substrate and the array substrate are bonded by the sealant, and then the sealant is cured by ultraviolet light, to cell-assemble the color filter substrate and the array substrate.
However, due to technical limitations, at present, the sealant can not be completely cured, thus affecting a cell-assembling effect of the color filter substrate and the array substrate, further affecting a display effect of a display device.
Embodiments of the present disclosure provide a color filter substrate and a manufacturing method thereof, and a display device and a manufacturing method thereof, for providing a structure in which all of a sealant can be irradiated, so that the sealant is completely cured, thus making a cell-assembled effect of the color filter substrate and the array substrate better.

However, for a LCD employed a narrow-frame technology, an aperture ratio of the GOA region of the array substrate is low, in this way, when the sealant is cured by the ultraviolet light, the ultraviolet light may only irradiate a part of the sealant after passing the GOA region, so that the sealant may not be cured completely, thus affecting a cell-assembled effect of the color filter substrate and the array substrate, further affecting a display effect of a display device.
