Matter, product quality, and improve the flexibility of product design.
Filter layer can be divided into dyestuff filter layer and interference filter layer, and traditional CF is exactly the principle that the dyestuff for using filters.
Dyestuff filter layer is that refractive index also changes, to some colors by adding dyestuff in the material, changing its molecular structure
Light by just changing, for example, when white light pass through orchil filter layer when, transmission is feux rouges, and blue and green light is big
It is partly absorbed.And the principle of interference filter layer is the light for controlling transmission by thicknesses of layers by the principle of optical interference
Wave-length coverage filters.
Interference filter layer is improved on the basis of Fabry-Perot interferometer and formed, thus also referred to as Fabry-

And, color film resin is replaced by using interference filter layer, the control to R, G, B chromaticity coordinates is more accurate, while making filter layer
Separated with panel, it is to avoid the problem of the display effect difference that CF segment differences etc. are caused, reduce separate out in dye-resin ageing process from
Influence of the sub- impurity to liquid crystal cell, it is to avoid the bad generation such as image retention.
Being discussed in detail for the technical scheme that the embodiment of the present application is provided is given below.
A kind of display panel that the embodiment of the present application is provided, including upper substrate, infrabasal plate, color film layer and tft array, its

According to the principle of interference of light, if as shown in Fig. 2 the refractive index of transparent spacers (abbreviation wall) 103 be n,
The thicknesses of layers of interlayer 103 is d, then the product of n and d determines the transmission peak value wavelength X of filter layer, and physical relationship formula is as follows：
Wherein m is default integer, for example can be 1,2,3, m is to the transmitance and half-peak breadth of the peak value of the wavelength of filter layer
Influence is produced, the half-peak breadth is the peak width at chromatogram peak height half, also known as half width.
By the optical filtering that different-thickness (different transmission peak value wavelength) is made in diverse location (from pixel (pixel) correspondence)
Layer, can reach the sub-pixel unit (R, G in dot, such as pixel, unit B) of different colours respectively through different wave length
The purpose of light.
