Colour filter, display device and preparation method for colour filter

TECHNICAL FIELD The present invention relates, there is provided a color filter, a color filter and a production method of a display apparatus. The color filter comprising: a substrate, and a black matrix layer and a color layer on the element substrate, the color unit disposed on the spacer layer is within the black matrix layer, wherein the color unit An opening is provided on the layer. The simple color filter structure, an opening formed in a certain unit on the color layer, such that more incident light can be transmitted through the color filter, and thus both meet the demand for color filters of colors, and can greatly improve the light transmittance of the color filter. While the present invention to improve the prior preparation process is not only to obtain a color filter having a specific shape through a special opening of the mask design, without making any changes to existing production lines can be implemented without increasing you can get better performance color filters when the device cost.
