    • It is an object to provide a display that can reliably shield visible light in the entire wavelength regions when viewed from an oblique direction and a viewing angle control element used for the display. A viewing angle control liquid crystal panel (2) is comprised of a liquid crystal cell (21) and an emission-side polarizing plate (22). When light having a part of wavelength components (R,G) in the visible wavelength regions enters at least at a predetermined angle, the liquid crystal cell (21) provides the incident light with a phase difference so as to function as a first light-shielding layer that shields the light of the R and G components not to pass through the emission-side polarizing plate (22). A retardation plate (4) and a polarizing plate (5) function as auxiliary light-shielding layers, more specifically, when the light that has passed through the first light-shielding layer enters at least at the predetermined angle, the retardation plate (4) provides the light with a phase difference so that at least light having a wavelength component (B) is shielded and thus not transmitted by the polarizing plate (5).
    • 本发明的目的是提供一种可以可靠地屏蔽从倾斜方向观察的整个波长区域中的可见光的显示器和用于显示器的视角控制元件。 视角控制液晶面板(2)由液晶单元(21)和发光侧偏光板(22)构成。 当具有可见波长区域中的波长成分(R,G)的一部分的光至少以规定的角度进入时,液晶单元(21)提供具有相位差的入射光, 屏蔽层,其遮蔽R和G成分的光不通过发射侧偏振片(22)。 相位差板(4)和偏振片(5)起辅助遮光层的作用,更具体地说,当穿过第一遮光层的光至少进入预定角度时,延迟板(4) )提供具有相位差的光,使得至少具有波长分量(B)的光被屏蔽,因此不被偏振片(5)传输。

    • The present invention provides a liquid crystal display device having improved transmittance. The liquid crystal display device according to the present invention has a first substrate and a second substrate disposed to face each other, and a liquid crystal layer interposed between the first substrate and the second substrate. The first substrate includes a pixel electrode to which a signal voltage is supplied and a common electrode to which a common voltage is supplied. The pixel electrode and the common electrode both comprise comb teeth. The comb teeth of the pixel electrode and the comb teeth of the common electrode are disposed with each other alternately via an interval. The liquid crystal layer contains liquid crystal molecules having positive dielectric anisotropy. The liquid crystal molecules are aligned in a direction orthogonal to a surface of the first substrate in a voltage non-application condition. The first substrate includes an extension wiring provided in a position overlapping at least one comb tooth of the comb teeth of the pixel electrode and the common electrode so as to extend along the at least one comb tooth via an insulating film, and the extension wiring serves as a wiring to which the signal voltage is supplied.
