摘要： An optical device is provided. The optical device includes a main body; a display unit which includes a polarization layer and which is disposed on one surface of the main body; and a camera module which is disposed in the main body and which overlaps the polarization layer in an optical axis direction. A first region of the polarization layer overlapping the camera module in the optical axis direction blocks or reflects at least some incident light when the camera module is not operated.

摘要： Embodiments disclose an optical material having a visual confirmation effect due to higher directivity of light reflection than a conventional optical material. Embodiments can include a laminate having a multilayer laminated film in which 11 or more layers of different thermoplastic resins are alternately laminated. With respect to light in a wavelength range of 400 to 700 nm and that is perpendicularly incident on an outer surface of the multilayer laminated film, the laminate has an average transmittance in the above wavelength range of 50% or more. When average reflectances in a wavelength range of 400 to 700 nm with respect to S-wave light in the wavelength range, incident at angles of 20° and 70° with respect to the normal line of the outer surface of the film at azimuths ϕn (n: 1 to 5), are given as Rs20(ϕn) and Rs70(ϕn), respectively, the laminate satisfies, at least one azimuth ϕn:Rs70(ϕn)−Rs20(ϕn)≥50(%).

摘要： Provided are a polarizing plate for antireflection containing a polarizer, and a protective layer formed on at least one surface of the polarizer, wherein the polarizing plate has a single transmittance of 44.6% or more and a degree of polarization of 98% or more, and a shrinkage rate in stretching direction of the polarizing plate is 0.5% or less after standing at 85° C. for 240 hours, and a display device including the polarizing plate. The polarizing plate is resistant to curling, prevents bending of a panel occurring after adherence of the panel, and reduces dispersion of reflection color depending on the position, while exhibiting high transmittance. Further, the polarizing plate can be made thinner, and prevent the polarizer from being cut off during a preparation process.

摘要： A head-up display includes a display element that emits display light indicating vehicle information, a case that accommodates the display element and has an emission port from which the display light is emitted to the outside, an optical element including a translucent dust cover that covers the emission port, and a phase element that is constituted from a plurality of phase difference plates having different polarization characteristics and is disposed at a prescribed inclination with respect to the principal ray of the display light. The phase element is designed by a first step for setting a light propagation characteristic of the optical element, and a second step for setting a target value of emission light of the optical element and calculating the polarization characteristics of each of the plurality of phase difference plates and the inclination serving as an approximate solution for the target value.
