    • PROBLEM TO BE SOLVED: To provide a display device that can display a bright picture without reducing a MTF.SOLUTION: A light guide plate 3 to which light emitted from a light source 2 is made incident emits light from a light emission plane 32. A prism sheet 5 reflects light of a predetermined angle of the light emitted from the light emission plane 32, causes the light to be made incident to the light guide plate 3 and transmits light of other angle. A polarization control element 8 is provided in parallel with the light emission plane 32 between a 1/4 wavelength plate 12 and a reflection type liquid crystal display element 1. The polarization control element 8 separates light emitted from the 1/4 wavelength plate 12 into a first polarization causing the light to be transmitted as illumination light to be made incident to the reflection type liquid crystal display element 1 and a second polarization causing the light to be reflected so as to be made incident to the light guide plate 3, and causes light modulated by the reflection type liquid crystal display element 1 and emitted to be reflected so as to move toward an imaging lens 10. The imaging lens 10 emits incident light toward a combiner 21.

    • PURPOSE:To share the refracting force to each face and to obtain the degree of freedom of the correction of aberration, so that the total length is reduced and the look-feeling of the finder is improved, by dividing the eyepiece forming a finder system in a paraxial area into two lenses. CONSTITUTION:Both an objective lens and eyepiece consists of two lenses, respectively. In this case, the lenses satisfy the conditions of Formulae I to IV. However, the DELTAX(0.6r2) of the formulae represents the degree of the pupil side face of the 1st lens. When an aspherical surface represented by Formula V, where phi is the height from the optical axis and (i) is a >=2 real number, is used as this aspherical surface, the value DELTAX, the difference between the aspherical surface and the spherical surface represented by Formula VI, at a height, phi= 0.62r2 from the optical axis, becomes the one shown by Formula VII. Therefore, the radius of curvature r4 of the surface at the pupil side can be determined by the specification of the finder. Accordingly, the radii of curvature r1 and r3 of the surfaces at the object side are selected so that they can take partial charge of the negative strong refracting power of these surfaces.
    • 目的:为了分享每个脸部的折射力并获得像差校正的自由度,通过将形成取景器系统的目镜分开,总长度减小,取景器的外观感觉得到改善 近轴区域成两个镜头。 构成:物镜和目镜都分别由两个镜头组成。 在这种情况下,透镜满足式I至IV的条件。 然而,公式的DELTAX(0.6r2)表示第一透镜的光瞳侧面的程度。 当由公式V表示的非球面表面,其中phi是来自光轴的高度,(i)是> = 2实数,用作该非球面,值DELTAX,非球面与球面之间的差 由式VI表示的离开光轴的高度,phi = 0.62r2,由式Ⅶ表示。 因此,瞳孔侧的表面的曲率半径r4可以通过取景器的规格来确定。 因此,选择物体侧的表面的曲率半径r1和r3,使得它们可以对这些表面的负强折射力进行部分充电。
