A liquid crystal display (LCD) device, comprising:
- first and second substrates, the first and second substrates having a plurality of pixels divided into at least two domains;
- a liquid crystal layer between the first and the second substrates, the liquid crystal layer having a different alignment direction in each domain;
- and
- first and second compensation films on outer surfaces of the first and second substrates, respectively, the first and second compensation films having a negative refractive anisotropy and each having a cross section having a triangle pattern.
A method for manufacturing a viewing angle compensation film for a liquid crystal display (LCD) device, comprising:
- forming a compensation film material having a negative refractive anisotropy;
- forming a patterned mask on the compensation film material, the patterned mask having a plurality of triangle patterns;
- and
- forming a plurality of triangle patterns on the compensation film material by pressing the compensation film material against the patterned mask.
A liquid crystal display (LCD) device, comprising:
- first and second substrates, the first and second substrates having a plurality of pixels divided into at least two domains;
- a liquid crystal layer between the first and the second substrates, the liquid crystal layer having a different alignment direction in each domain;
- a first compensation film on an outer surface of the first substrate, the first compensation film having an upper surface and a lower surface;
- and
- a second compensation film on an outer surface of the second substrate, the second compensation film having an upper surface and a lower surface, the first and second compensation films having a negative refractive anisotropy;
- wherein at least one of the first compensation film upper surface and lower surface and at least one of the second compensation film upper surface and lower surface has a triangular cross section.
