  • Optical compensation sheet, polarizing plate and liquid crystal display
    Publication number: 20050105027
    Abstract: To provide a high-display-quality optical compensation sheet and a liquid crystal display having the optical member without inducing a problem, such as light leakage due to thermal distortion, the optical compensation sheet for a liquid crystal display, the liquid crystal display containing: a liquid crystal cell having a glass plate; and a polarizing plate having the optical compensation film faced to the glass plate, wherein a thickness of the optical compensation sheet, a photoelastic coefficient of the optical compensation and a photoelastic coefficient of the glass plate satisfy the condition specified in the specification.
