Fig. 3 represents the guidance panel 110 of comparative example 1, and Fig. 4 represents the guidance panel 210 of comparative example 2.The structure of Fig. 3 and display panels 30 shown in Figure 4 is identical with display panels 30 shown in Figure 2.In the guidance panel 210 of the guidance panel 110 of comparative example 1 and comparative example 2, to partly marking same-sign and detailed with guidance panel 10 same structures shown in Figure 2.
In the guidance panel 110 of comparative example shown in Figure 31, the bonding coat 122 between polarizing coating 21 and the protective sheet 23 does not comprise pigment or dyestuff, does not have the function of complementary color layer.Replace this structure, in the supporting substrates 111 of guidance panel 110, sneak into pigment or dyestuff, make supporting substrates 111 have function as complementary color layer.
The guidance panel 210 of comparative example 2 shown in Figure 4 is same with guidance panel 110, and the bonding coat 122 between polarizing coating 21 and the protective sheet 23 does not comprise pigment or dyestuff, does not have the function of complementary color layer.In addition, supporting substrates 11 does not comprise pigment or dyestuff yet, does not play a role as complementary color layer.Replace this structure, the bonding coat 219 between the λ of upside/4 phase retardation films 15 and the polarizing coating 21 comprises pigment or dyestuff, and this bonding coat 219 plays a role as complementary color layer.
In following table 1, show the result that the function of the guidance panel 210 of the guidance panel 110 of guidance panel 10 to embodiment shown in Figure 20, comparative example 1 shown in Figure 3, comparative example 2 shown in Figure 4 compares.
The guidance panel 110,210 of guidance panel 10 and comparative example all uses the complementary color layer that has comprised pigment or dyestuff.This complementary color layer can be adjusted colourity basically by adjusting kind and the amount of pigment or dyestuff.
In the guidance panel 110 of comparative example 1, the supporting substrates 111 that plays a role as complementary color layer is between polarizing coating 41 and λ/4 phase retardation films 13.Diffuse reflection or diffusion occur for the inside at supporting substrates 111 in the polarized light state that therefore, becomes the colored display light of rectilinearly polarized light under polarizing coating 41 effect.Therefore, the rectilinearly polarized light that has passed through the circularly polarized light of λ/4 phase retardation films 13 and passed through the λ of upside/4 phase retardation films 15 produces disorderly.Thereby the light quantity of the polarizing coating 21 of transmission upside reduces, and causes the colored contrast that shows to reduce.
In the guidance panel 210 of comparative example 2, the bonding coat 219 that plays a role as complementary color layer is between the λ of upside/4 phase retardation films 15 and polarizing coating 21.Therefore, transmission the rectilinearly polarized light of colored display light of the λ of upside/4 phase retardation films 15 by diffuse reflection or diffusion, the light quantity of the polarizing coating 21 of transmission upside reduces, the colored contrast that shows reduces.
And then, in the guidance panel 210 of comparative example 2, incide becoming after the rectilinearly polarized light by polarizing coating 21 from the light of outside of guidance panel 210 through protective sheet 23, diffuse reflection or diffusion occur in the inside of the bonding coat 219 that comprises pigment or dyestuff.And then, in the space 18 and the circularly polarized light transmission λ of the boundary portion of lower conducting layer 14 reflection/4 phase retardation films 15 and after becoming rectilinearly polarized light, also interior by diffuse reflection or diffusion at bonding coat 219.Thereby, containing the composition towards the axis of homology of polarizing coating 21 in the catoptrical rectilinearly polarized light, outer reflection of light preventing effectiveness reduces.
And then in guidance panel shown in Figure 3 110, owing to comprise pigment or dyestuff in the supporting substrates 111, therefore, the complementary color layer 22 that comprises pigment or dyestuff with as shown in Figure 2 bonding coat is compared, and manufacturing cost uprises.
