In addition, optical compensation films 23 can have the work of the uniaxial phase compensation such as the phase compensation of A plates or C plate phase compensations
With, or there is A+C plates (double optical axises) effect of phase compensation.
From Fig. 3 to Fig. 5, the liquid crystal display device 2 of the application, by the first film layer possessed by optical compensation films 23
231st, the second film layer 232, third membrane layer 233, and the 4th film layer 234, the first film layer 231, the second film layer 232, third membrane layer 233
And 234 layers of the 4th film layer stacks each other, and there is the different first refractive index of numerical value, the second refractive index, third reflect rate respectively,
And fourth refractive index, wherein first refractive index is less than the second refractive index, and third reflect rate is less than the design of fourth refractive index, can
Solve the change of visible angle when absorbing axis change shifting from Polarizer when the angle of sight and Polarizer absorption axiss, and have and reduce
Light leaks and the effect of blast and phase compensation simultaneously.
Above content is to combine the further description that specific embodiment is made to the application, it is impossible to assert this Shen
Specific implementation please is confined to these explanations.For the application person of an ordinary skill in the technical field, do not taking off
On the premise of conceiving from the application, some simple deduction or replace can also be made, should all be considered as belonging to the protection of the application
Scope.
