Field of the Invention The present invention relates to an optical element and a display device thereof, and more particularly to a color filter element and a liquid crystal display device therefor. [Prior Art] With the popularization of liquid crystal display devices, they are widely used in indoor electronic products such as general desktop computers, home televisions, etc. In recent years, liquid crystal display devices are more portable products. Significantly increase the proportion of its use, such as: portable computer@机, personal digital assistant... and so on. Moreover, the liquid crystal display device used in the above is a transmissive liquid crystal display device, a reflective liquid crystal display device or a transflective liquid crystal display device, and is a display device structure in a conventional liquid crystal display device. The system includes a halogen array element 12, a color filter element 16 and a liquid crystal layer 14. Please refer to the cross-sectional schematic diagram of the partial structure of the conventional transmissive liquid crystal display device shown in the first figure, from the backlight module (not The light source shown in the figure is a mixture of multi-color light and white light. After passing through the liquid crystal layer 14, it can be known according to the relationship shown in the following formula (1): n*d/A = phase delay amount.. .........(1) 相位The phenomenon of phase delay occurs in each color light, and the phase delay amount is the difference between the birefringence of the liquid crystal molecules themselves, the path through which the light passes (9), and the wavelength of the colored light ( λ) has a relationship 'in the conventional crystal display II' liquid crystal layer birefringence difference is fixed, and the light path (ie, the thickness of the liquid crystal layer) is also the same, the only difference is included in the backlight source Red light, green light And the color of the blue light has different wavelengths of light, so the light of each color is delayed by the thickness of the service layer, and her delay is the final display: the color of the performance is different from that of the input. To correct the color to the same as the input 即, the phase delay amount is compensated. In the conventional transmissive liquid crystal display device, only the single-phase phase is added to the gamma-phase, and the actual effect is only necessary for the accurate adjustment of one of the two color lights. The other two types of 200933208 different wavelengths of color light can only achieve partial adjustment effect. For example, if the phase compensation film 18 is designed for the green wavelength, the red and blue light passing through the phase delay amount cannot be completely The ground is adjusted, thus reducing the quality of the image display. In addition, for the transflective liquid crystal display, in addition to the problem that the amount of phase delay between the lights of different colors is different, the problem that the phase delay amount is different due to the difference in the light path between the different penetrating lines and the reflecting wire is required to be separately compensated. . Therefore, based on the above-described deficiencies, the present invention proposes a color filter element and a display device therefor. SUMMARY OF THE INVENTION The main object of the present invention is to provide a color light-emitting device and a liquid crystal display device thereof, which are formed by combining a phase adjustment layer and a filter unit on a substrate, and using filter units of different thicknesses. The thickness of the layer is adjusted to match the phase adjustment layer so that the phase adjustment layer can simultaneously adjust the optical phase retardation amount according to different color light wavelengths and make the liquid crystal display device liquid crystal layer have a uniform thickness. Another object of the present invention is to provide a color filter element and a liquid crystal display device thereof, which are formed by combining a phase adjustment layer and a filter unit on a substrate, and using different thickness filter units to adjust the phase adjustment. The thickness of the layer is such that the phase adjustment layer removes the phase adjustment of the different color lights, and at the same time adjusts the optical phase delay amount according to the penetrating light source and the reflected light source. A further object of the present invention is to provide a color filter element and a liquid crystal display device thereof for phase adjustment of color light of different wavelengths and at the same time with the design of the polarizer to enhance the black surface effect of the three-dimensional image. In order to achieve the above object, the present invention firstly provides a color filter component, which comprises a substrate, at least two color filter units, and at least two phase adjustments respectively associated with the two colors are disposed on the substrate. The adjustment layer is a material having a birefringence, such as a liquid crystal material, and defines a suitable thickness according to a phase retardation amount after passing through the liquid crystal layer of each color light wavelength, and the thickness of each corresponding filter unit is also determined. The sum of the thicknesses of the color filter 6 200933208 and the phase adjustment layer matched with it is substantially the same. In addition, when the liquid crystal display device is a half-transparent and semi-reflective liquid crystal display device, the phase adjustment layer thickness required for the penetration region and the reflection region can be determined according to the phase retardation amount to be compensated by the penetration region and the reflection region, and The filter unit of the appropriate thickness is respectively matched with the total thickness of the filter unit and the phase adjustment layer of the penetration region and the total thickness of the filter unit and the phase adjustment layer of the reflection region to form a single liquid crystal layer thickness. Semi-transflective liquid crystal display. The purpose, technical contents, features, and effects achieved by the present invention will become more apparent from the detailed description of the embodiments and the accompanying drawings. [Embodiment] In order to compensate for the amount of phase delay generated by a light source of a different wavelength in a liquid crystal display device after passing through a liquid crystal layer, the present invention provides a color filter element and a liquid crystal display device using the same, The embodiment of the present invention and the corresponding drawings are disclosed to explain in detail the detailed structure of the color filter element and the liquid crystal display device of the present invention. First, please refer to the third (A) and third (B) drawings, wherein the third (A) is the first embodiment of the color filter element of the present invention, and the third (B) The plan is a schematic cross-sectional view of a partial structure of the third (A) diagram. The color filter element 26 includes a substrate 265 ′ and a light shielding layer 264 is disposed on the substrate 265 and a gap formed by the light shielding layer 264. A first filter unit 261, a second filter unit 262, and a third filter unit 263 are formed in the area, at least two of the filter units are different in color, for example, the first filter unit 261 is a red filter unit and the second filter is The light unit 262 is a green filter unit. According to the magnitude of the phase retardation, it is proportional to the birefringence of the liquid crystal molecules and the path length through which the light passes, and the phase retardation amount of the red, green and blue light after passing through the liquid crystal layer is different in inverse relationship with the wavelength of the color light. The phase compensation amount required to provide each color light by the phase adjustment layer having different thicknesses is a liquid crystal display for producing a single-thickness liquid crystal layer, the first filter unit 261, and the second filter.
