摘要： A planar light source, Fresnel lens sheet, and louver are disposed in the stated order in a light source apparatus. The Fresnel lens sheet deflects and focuses in one dimension light that has entered from the planar light source. The louver is disposed in the optical path of the light emitted from the Fresnel lens sheet, and the directivity of the light can be increased by restricting the traveling direction of the light to the focal direction of the Fresnel lens sheet. The light utilization ratio can thereby be increased, the directivity of planarly emitted light can be increased, and the brightness can be made uniform at the point of observation.

摘要： A plurality of pixels is arranged periodically in the x-axis direction and the y-axis direction in the display panel of a display device, and because light is blocked by the portion other than the open part in each pixel, the display panel has a two-dimensional lattice structure. The pixels are rectangular, and the length Px of the long edges in the x direction is larger than the length Py of the short edges in the y direction. A louver, in which transparent regions and non-transparent regions are arranged periodically in a one-dimensional direction, is provided on the display panel, and the angle formed by the x axis and the one-dimensional period direction of the louver is 45 degrees or less, and preferably 10 degrees or less. This configuration makes it possible to obtain an optical element having high directivity, reduced moiré, and high transmittance. It is also possible to obtain a display device having excellent display quality into which the optical element is incorporated.
摘要翻译：多个像素在显示装置的显示面板中的x轴方向和y轴方向周期性地排列，并且由于光被每个像素中的开放部分以外的部分阻挡，所以显示面板具有二维晶格结构。像素是矩形的，并且长边缘在x方向上的长度Px大于y方向上的短边的长度Py。在显示面板上设置有透明区域和非透明区域在一维方向周期性地布置的百叶窗，并且由x轴和百叶窗的一维周期方向形成的角度为45度以下，优选为10度以下。通过该结构，能够获得具有高方向性，降低的莫尔条纹和高透射率的光学元件。还可以获得具有优异的显示质量的显示装置，其中结合有光学元件。

摘要： A display device is composed of a light source device and a transmissive liquid crystal display panel, and the light source device is provided with a transparent/scattering switching element capable of switching between states in which incident light is transmitted or scattered. Pixels for displaying are disposed in the form of a matrix in the transmissive liquid crystal display panel, and the need for another power supply and signals for the transparent/scattering switching element is eliminated by driving the transparent/scattering switching element using the signals and power supply for driving the pixels. The drive power source of the transparent/scattering switching element for controlling scattering can be made smaller and less costly in a display device that is capable of switching the range of viewing angles.

摘要： In the liquid crystal display device of the present invention, a circular polarizer is provided to each of a pair of substrates that hold a liquid crystal layer, wherein the circular polarizer on the display surface side is composed of a polarizer, λ/2 plate in which Rth>0, and a λ/4 plate in which Rth 0. Rth is a retardation in the thickness direction of a λ/2 plate or a λ/4 plate. A reduction is achieved in the absolute value of the sum of the Rth between the λ/2 plate for which Rth>0 and the λ/2 plate for which Rth 0. A circular polarizer having excellent wavelength characteristics and excellent viewing angle characteristics when viewed at an angle is thereby obtained, and a liquid crystal display device and a terminal device that use the circular polarizer are obtained.
