| 发明名称 | Polarizing plate and liquid crystal display apparatus including the same | ||
| 摘要 | A polarizing plate includes a polarizer, a retardation film on a first side (e.g., a lower side) of the polarizer, and a protective film on a second side (e.g., an upper side) of the polarizer. The retardation film has an axis distortion angle between a fast axis of the retardation film and an absorption axis of the polarizer of about +0.03° to less than +0.2°. The protective film has an in-plane phase difference (Ro) of greater than about 10,000 nm and about 15,000 nm or less at a wavelength of 550 nm. A liquid crystal display apparatus includes the polarizing plate. | ||

| 主权项 | 1. A polarizing plate comprising: a polarizer; a retardation film on a first side of the polarizer; and a protective film on a second side of the polarizer, wherein an axis distortion angle between a fast axis of the retardation film and an absorption axis of the polarizer is about +0.05° to about +0.15°, and the protective film has an in-plane phase difference (Ro) of greater than about 10,000 nm to about 15,000 nm or less at a wavelength of 550 nm. | ||
