The second transparent body 421 can be a glass substrate / and the first electrode layer 412 of the first substrate 41 is opposite to the second electrode layer 424 of the second substrate 42 .

Correspondingly, the second electrical system 442 is corresponding to the halogen electrode Be. In addition, the materials of the first voltage control tUM41 and the second dust control unit 442 can be determined according to the actual design 12 200846744.

In other words, the first dielectric constant ～ the optical layer 422 (designed with the first taiy 1 field, For example, if the wavelength 13 200846744 of the filtered light of the first filter SUe 441 _ is greater than the wavelength of the filtered light of the second filter layer 423 (corresponding to the second voltage control unit 442), the first dielectric The constant ε4ι is designed to be larger than the second dielectric constant ε42 such that the voltage actually received by the region 431 of the liquid crystal layer 43· is greater than the voltage actually received by the region 432 of the liquid crystal layer 43. Since the phase retardation amount (δϋη) is substantially positively correlated with the voltage actually received by the liquid crystal layer 43, the phase retardation amount of the region 431 in which the light of different wavelengths passes through the liquid crystal layer 43 is larger than the phase retardation amount of the region 432 of the liquid crystal layer 43. Further, even if the light of the same wavelength passes through the liquid crystal layer 43, the same phase retardation wavelength ratio (δϋη/λ〇) can be obtained, which not only improves the contrast but also reduces the generation of the color shift. In addition, the liquid crystal display panel 4 may further include two polarizers 45 and 46 respectively disposed on one side of the second substrate 42 and one side of the first substrate 41. In this embodiment, the polarizer 45, The polarization axis of 46 is exemplified by an orthogonal setting.

At this time, the phase retardation wavelength ratio (δ^/λο) of the blue light (45Onm) to the liquid crystal layer 43 is calculated to be 0.72 (275 nm/450 nm), and the green light (550 nm) The phase retardation wavelength ratio (δοη/λ〇) to the liquid crystal layer 43 is calculated as 200846744 I5 9 (27 5 nm/550 nm) in which the phase retardation wavelengths of the regions 431, 432, and 433 of the liquid crystal layer 43 are made different rays. The ratio is the same as (δ^/λο) to reduce the color shift. Therefore, the operator can first calculate the phase retardation wavelength ratio δοη/λ〇 of the regions 431, 432, and 433 of the liquid crystal layer 43 to 0.5.

It can be found from the curve Sc that the phase retardation of the blue light (45 〇 nm) to the liquid crystal layer 43 is found. When the length ratio δ^/λο is 〇.5, the voltage corresponding to the first filter layer 425 on the region of the liquid crystal layer 43 is required to be subjected to a voltage of σ10 of 3.47V, which can be found by the curve S42. When the green light (550 nm) to the liquid crystal layer 43 (four)-bit retardation wavelength ratio is 〇·5, ::曰: the region 43 of the layer 43 (corresponding to the second filter layer 423) The voltage that is still tolerated is 4.24V . Therefore, when the voltages required for the regions 1 432, 433 of the liquid crystal layer 43 are 5v, 4.2, and 47V, respectively, the equivalent dielectric constant of the regions 431, 432, and 433 of the liquid crystal layer 43 can be in accordance with the figure. 9 and got.

The first dielectric constant ε61 of the first voltage control unit 641 is larger than the second dielectric constant ε62 of the second voltage control unit 642, so that between the halogen electrode Ρ6〇 and the second electrode layer 623 When a voltage is applied, the region 631 of the liquid crystal layer 63 (the penetration region corresponding to the first voltage control portion 641) is actually subjected to a voltage greater than the region 632 of the liquid crystal layer 63 (the reflection region corresponding to the second voltage control portion 642). The voltage withstand is such that the reflected light and the transmitted light have substantially the same phase delay, which not only reduces the generation of color shift, but also the first voltage control unit 25 200846744 641 and the second voltage control unit 642 of the voltage control layer 64 are designed.

The voltage control layer 74 is a polymerized liquid crystal material coated with a layer of polymerized liquid crystal. After the material is applied to the first electrode layer, respectively, different voltages are applied to the first region and the second region of the voltage control layer 74, so that the alignment angles of the polymerized liquid crystal materials in the two regions are different, and the dielectric constants of the two regions are different. The first voltage control unit 541 and the second voltage control unit 542 are formed, and the polymerizable liquid crystal material may be a photopolymerizable liquid crystal material or a thermal polymerization liquid crystal material, so that the voltage modulation polymerized liquid crystal material is arranged.
