Title:
LAMINATED POLARIZING PLATE AND HORIZONTAL ALIGNMENT LIQUID CRYSTAL DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/157182
Kind Code:
A1
Abstract:
Provided are a laminated polarizing plate having superior field of view characteristics and a horizontal alignment liquid crystal display device. The laminated polarizing plate results from laminating, in the given order, at least a first polarizing plate, a first optically anisotropic layer, and a second optically anisotropic layer. The first optically anisotropic layer satisfies [1]-[7], the second optically anisotropic layer satisfies [8] and [9], and the first optically anisotropic layer and second optically anisotropic layer satisfy [10]. [1]: 50 nm ≤ Re1 (550) ≤ 200 nm. [2]: 30 nm ≤ Rth1 (550) ≤ 330 nm. [3]: 0.5 ≤ Rth1 (550)/Re1 (550) ≤ 1.5. [4]: 0.7 ≤ Re1 (450)/Re1 (550) < 1.1. [5]: 0.7 ≤ Rth1 (450)/Rth1 (550) < 1.1. [6]: 0.95 ≤ Re1 (650)/Re1 (550) < 1.2. [7]: 0.95 ≤ Rth1 (650)/Rth1 (550) < 1.2. [8]: -10 nm ≤ Re2 (550) ≤ 10 nm. [9]: -200 nm ≤ Rth2 (550) ≤ -50 nm. [10]: -60 nm ≤ Rth1 (550) + Rth2 (550) ≤ 60 nm. (Here, Re and Re 2 are the in-plane retardation values for the first and second optically anisotropic layers, and Rth1 and Rth2 are the thickness-direction retardation values of the first and second optically anisotropic layers.)
