20110058128 | Liquid crystal display apparatus - An E-type polarizing layer is provided between a pair of orthogonally oriented O-type polarizing layers, and alternatively, an O-type polarizing layer and an E-type polarizing layer which are oriented orthogonal to each other are provided. When a liquid crystal layer has a slow axis, the E-type polarizing layer is disposed so that an absorption axis thereof is orthogonal to the slow axis. Therefore, a liquid crystal display device having a wide viewing angle is realized in which a contrast ratio is improved by suppressing a light leakage occurring when observed from an oblique direction. | 03-10-2011 |
