摘要： A phase difference element, in which imbalance hardly occurs between right and left pictures during displaying a three-dimensional image, and a display device having the phase difference element are provided. A base film of the phase difference element includes, for example, a thin resin film having optical anisotropy. A slow axis of the base film points in a vertical or horizontal direction, and points in a direction intersecting with a slow axis of a right-eye region of the phase difference element and with a slow axis of a left-eye region thereof. Thus, influence due to optical anisotropy of the base film is exerted on each light being transmitted by the base film, so that the influence is not extremely greatly exerted on only one of light corresponding to a right eye and light corresponding to a left eye, the respective light being transmitted by the base film.

摘要： A light-transmitting film that has a predetermined polarization split function, in addition to a light-collecting function is provided. The index of refraction nx in a prism extension direction and the index of refraction in a prism alignment direction differ from each other. By generating a difference in the indices of refraction in the prism extension direction and the prism alignment direction orthogonal thereto, for the light incident on the light-transmitting film, the polarization component Lx oscillating in the prism extension direction and the polarization component Ly oscillating in the prism alignment direction can have different transmission characteristics. For example, by setting the index of refraction in the prism extension direction greater than the index of refraction in the prism alignment direction (nx>ny), among the light incident on the light-transmitting film, the amount of return light of the polarization component Lx oscillating in the prism extension direction is greater than that of the polarization component Ly oscillating in the prism alignment direction. In this way, not only a light-collecting function, but also a predetermined polarization split function is obtained.

摘要： According to the present invention, by controlling the angular distribution of the light outputted from a light guide plate to enable the angular brightness distribution of the light emitted from a backlight device to be controlled, the thickness of a liquid crystal display apparatus having the backlight device is reduced as well as the brightness is improved due to the reduction in returned light amount. Furthermore, since light is sufficiently mixed in the light guide plate, light sources with comparative large unevenness are enabled to be used.A backlight device according to the present invention includes a hole or a projection formed on the light outgoing plane of a light guide plate or the back plane opposing the light-outgoing plane, and a side face of the hole or the projection is directed roughly perpendicularly to the light-outgoing plane. Furthermore, specular reflection plates are arranged on the bottom plane and the side faces of the light guide plate. The angular distribution of light from a light source is maintained due to the roughly perpendicular side face of the hole or the projection so that the light is led within the light guide plate and outputted outside.

A luminance enhancement film has a plurality of convex sections which extend toward in the horizontal direction and are arranged in the direction crossing the extending direction, and in which the refractive index in the extending direction is larger than the refractive index in the arrangement direction. A wave plate changes the polarization direction of light entering the wave plate so that an angle made by a polarization direction of the polarization component in the arrangement direction of the convex section after passing through the wave plate among light passing through the luminance enhancement film and the direction of a polarizing axis a of a first polarizer becomes small. A second polarizer has a polarizing axis b that transmits the polarization component in the vertical direction.
