- the pixel unit can also include sub-pixels of other colors.
- the material forming the color film layer is preferably a resin, and may of course be other materials, for example, an inorganic material or the like. In the embodiment of the present invention, the material forming the color film layer is exemplified as a resin.
- the "film” refers to a film formed by deposition or other processes on a substrate using a certain material. If the “film” does not require a patterning process throughout the manufacturing process, the “film” may also be referred to as a “layer”; if the “film” requires a patterning process throughout the manufacturing process, it is referred to as "before the patterning process”.
- the film " is called a "layer” after the patterning process.
- the "layer” after the patterning process contains at least one film "pattern”. For example, the above color film layer is formed by a resin film after a patterning process, and each sub-pixel is a pattern.
- the pixel unit on the color filter substrate includes a red sub-subpixel 31, a green sub-pixel 32, and a blue sub-pixel 33. Since the wavelength of the red light is greater than the wavelength of the green light, and the wavelength of the green light is greater than the wavelength of the blue light, the area S1 of the red sub-sub-pixel 31 is smaller than the area S2 of the green sub-sub-pixel 32, and the area of the green sub-sub-pixel 32. S2 is smaller than the area S3 of the blue sub-pixel 33.
