Embodiment
[first embodiment]
Fig. 2 is the partial cutaway schematic of a kind of chromatic filter layer of the first embodiment of the present invention.Please refer to Fig. 2, the chromatic filter layer 200 of present embodiment comprise a substrate 210 and a plurality of colorized optical filtering storehouse pattern 220R, 220G, 220B ..., wherein colorized optical filtering storehouse pattern 220R, 220G, 220B ... be disposed on the substrate 210.On the practice, colorized optical filtering storehouse pattern 220R, 220G, 220B ... different colors can be arranged according to design requirement, for example red, green, blue ....In addition, chromatic filter layer 200 can further be provided with black matrix pattern BM, with the colorized optical filtering storehouse pattern 220R that avoids different colours, 220G, 220B ... the situation of mutual colour mixture takes place.
In the present embodiment, each colorized optical filtering storehouse pattern 220R, 220G, 220B ... comprise two kinds of colored filter film, and these two kinds of interlaced storehouses of colored filter film.Particularly, as Fig. 2 and shown in Figure 3, wherein Fig. 3 is according to a partial cutaway schematic that colorized optical filtering storehouse pattern is painted among Fig. 2.Colorized optical filtering storehouse pattern 220G comprises at least one pure matter (pure) colored filter film 222 and at least one upgrading (modified) colored filter film 224, wherein pure matter colored filter film 222 and upgrading colored filter film 224 interleaving stacks.For instance, the colorized optical filtering storehouse pattern 220G that Fig. 3 illustrated is formed by two-layer pure matter colored filter film 222 and three layers of upgrading colored filter film 224 interleaving stack.
In the present embodiment, the refractive index of upgrading colored filter film 224 is different from the refractive index of pure matter colored filter film 222.Therefore, from another perspective, the colored filter film interleaving stack that colorized optical filtering storehouse pattern 220G can be described as by two kinds of different refractivities forms.Further say, pure matter colored filter film 222 for example is a pure matter look resistance (pure color photoresist), and upgrading colored filter film 224 comprises a pure matter look resistance and refractive index adjustment agent, and wherein the material of refractive index adjustment agent comprises alcohols, benzene class, ester class or above-mentioned arbitrary combination.
Because pure matter colored filter film 222 has different refractive indexes respectively with upgrading colored filter film 224, therefore, as shown in Figure 3, when light L when upgrading colored filter film 224 penetrates and is incident to the pure matter of next layer colored filter film 222, light L changes its original direct of travel.In like manner, afterwards when light L when pure matter colored filter film 222 penetrates and is incident to next layer upgrading colored filter film 224, light L can change its direct of travel once more.Ensuing so, by that analogy other rete.
From the above, light L is when the interface of the pure matter colored filter film 222 of passing through two kinds of different refractivities and upgrading colored filter film 224, the direct of travel of light L can be along with change, and the design that is formed by the colored filter film interleaving stack of two kinds of different refractivities like this can make the light by chromatic filter layer 200 have good chromaticity.Specifically, suppose that colorized optical filtering storehouse pattern 220R, 220G and 220B are respectively red colorized optical filtering storehouse pattern, green colorized optical filtering storehouse pattern and blue colorized optical filtering storehouse pattern, light L is after passing through colorized optical filtering storehouse pattern 220R, the 220G and 220B of present embodiment, and the colour purity of ruddiness, green glow and blue light and color saturation can improve.In a preferred embodiment, the refractive index of pure matter colored filter film 222 is in fact between 1.3 and 1.8, and the refractive index of upgrading colored filter film 224 is in fact between 1.5 and 2.0, and chromatic filter layer 200 can have better optical characteristics.
In addition, in the present embodiment, when the upgrading colored filter film 224 of chromatic filter layer 220 had the refractive index adjustment agent of different weight percent, the optical characteristics of chromatic filter layer 200 also can be different.As table one and shown in Figure 4, Sample A in the table one, Sample B, SampleC and Sample D illustrate the green optical filtering storehouse pattern that four kinds of different refractivities are adjusted the percentage by weight of agent respectively, and Fig. 4 has the wavelength of chromatic filter layer of this green optical filtering storehouse pattern and the characteristic curve diagram of penetration, and wherein the characteristic curve of the wavelength of Sample A, Sample B, Sample C and SampleD and penetration corresponds to curve 401, curve 403, curve 405 and curve 407 respectively.
Table one
| Green optical filtering storehouse pattern | Refractive index adjustment agent (g) | Pure matter green filter film (g) | Refractive index is adjusted the percentage by weight (%) of agent than last pure matter green filter film |
| Sample?A | 0 | 1.15 | 0 |
| Sample?B | 0.0117 | 1.15 | 1.017 |
| Sample?C | 0.0296 | 1.15 | 2.573 |
| Sample?D | 0.0591 | 1.15 | 5.139 |
Sample A from table one and the curve among Sample B and Fig. 4 401 learn that with curve 403 Sample B has refractive index adjustment agent Sample A and then do not have.When light respectively by behind Sample A, the B, the light penetration of the ruddiness of Sample B (long wavelength) and blue light (short wavelength) is than next low of Sample A.In other words, with regard to the colour purity and color saturation of green glow, Sample B has more higher colour purity and color saturation than Sample A.
Further, curve 403 among Sample B from table one, Sample C and Sample D and Fig. 4, curve 405 are learnt with curve 407, when Sample D has more refractive index adjustment agent than Sample B, C, with regard to the colour purity and color saturation of green glow, Sample D can have higher colour purity and color saturation.
In like manner can know by inference, in other embodiments, other color (for example red, blue ...) colorized optical filtering storehouse pattern also can make the light after the filtration have high-quality colour purity and color saturation.Therefore, the chromatic filter layer 200 of present embodiment is applied in the display device, then helps to promote the color representation of display device.
Moreover, compared to traditional individual layer colorized optical filtering storehouse pattern, the colorized optical filtering storehouse pattern 220R of present embodiment, 220G, 220B ... have thin thickness.By Fig. 2, Fig. 3 as can be known, the thickness of the upgrading colored filter film 224 of present embodiment is less than the thickness of pure matter colored filter film 222, therefore, each colorized optical filtering storehouse pattern 220R, 220G, 220B ... whole thickness can be less than traditional individual layer colorized optical filtering storehouse pattern.In a preferred embodiment, colorized optical filtering storehouse pattern 220R, 220G, 220B or ... thickness can reach below 2 microns in fact.
