    • A display apparatus comprises a display panel, a first polarizing plate and a second polarizing plate. The display panel comprises a first substrate including a pixel electrode, a second substrate opposite to the first substrate, and a liquid crystal layer disposed between a first surface of the first substrate and a first surface of the second substrate. The first polarizing plate comprises a first polarizer having a first polarizing axis, and a first λ/4 phase difference plate having a refractive index between about 1.35 and about 2.05 in a thickness direction. The second polarizing plate comprises a second polarizer having a second polarizing axis crossing the first polarizing axis, and a second λ/4 phase difference plate having a refractive index between about 1.35 and about 2.05 in a thickness direction. Accordingly, light leakage in a side view may be reduced and viewing angle may be improved.
    • 显示装置包括显示面板,第一偏振片和第二偏振片。 显示面板包括:第一基板,包括像素电极,与第一基板相对的第二基板;以及液晶层,设置在第一基板的第一表面和第二基板的第一表面之间。 第一偏振板包括具有第一偏振轴的第一偏振片和厚度方向上折射率约为1.35至约2.05的第一λ/ 4相位差板。 第二偏振板包括具有与第一偏振轴交叉的第二偏振轴的第二偏振片和在厚度方向上的折射率在约1.35和约2.05之间的第二λ/ 4相位差板。 因此,可以减小侧视图中的漏光,并且可以提高视角。
