Title:
COMPOSITE POLARIZING PLATE AND LIQUID CRYSTAL PANEL USING SAME
Document Type and Number:
WIPO Patent Application WO/2017/047406
Kind Code:
A1
Abstract:
Provided is a composite polarizing plate that experiences little reduction in degree of polarization in high-temperature or high-temperature/high-humidity environments. Also provided is a liquid crystal panel that has high heat resistance and high wet-heat resistance. A composite polarizing plate in which are laminated, in order, a low-moisture-permeability layer that has a moisture permeability of 200 g/m2∙24 hr or less, a first polarizing film that has a thickness of 15 μm or less, and a second polarizing film that has a thickness of 15 μm or less. The absorption axis of the first polarizing film and the absorption axis of the second polarizing film are approximately parallel.
