Document Type and Number:
WIPO Patent Application WO/2018/064855
Kind Code:
A1
Abstract:
A circular polarizing plate (100) comprises a 1/4 wave plate (11) and a first linear polarizing plate which are arranged in a laminated manner, the 1/4 wave plate (11) comprising a plurality of projection areas, each projection area comprising a first projection (111), a second projection (112) and a third projection (113) which are sequentially arranged, the first projection (111), the second projection (112) and the third projection (113) being respectively used for transmitting red light, green light and blue light, the thickness of the first projection (111) being dR, the thickness of the second projection (112) being dG, and the thickness of the third projection (113) being dB, dR =λR/4ΔnR,dG =λG/4ΔnG,and dB =λB/4ΔnB; and λR, λG, and λB being wavelengths of the red light, green light and blue light respectively, andΔnR, ΔnG, and ΔnB being birefringence rates of the red light, green light and blue light in the 1/4 wave plate (11) respectively. A liquid crystal display (200) and an electronic device can improve a large-visual-angle color shift effect of different colors and improve display performance.
