摘要： In a display device equipped with a light source device, a second light-guide member is provided to the back surface of a first light-guide member that has an emitted light control sheet provided to the front surface thereof. The emitted light control sheet is composed of a flat plate portion and protrusions. A first light source mounted to a side surface of the first light-guide member, and a second light source mounted to a side surface of a second light-guide member are switched and turned on. The emitted light control sheet has light-condensing effects when the first light source is on, and has diffusing effects when the second light source is turned on. The angle range of illuminating light can thereby be switched.

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 translucent liquid crystal display panel (2) includes pixel pairs as display units each formed by a left-eye pixel (4L) and a right-eye pixel (4R) and arranged in a matrix shape. A through hole (4Ld) arranged in a color layer (4Lc) of a color filter has a slit shape whose longitudinal direction is identical to the orientation direction of a cylindrical lens (3a) constituting a lenticular lens (3). Similarly, a through hole (4Rd) arranged in a color layer (4Rc) of a color filter has a slit shape whose longitudinal direction is identical to the orientation direction of the cylindrical lens (3a) constituting the lenticular lens (3). This suppresses the phenomenon that a hue is changed by a field-of-view angle and/or an external light condition on the translucent display panel capable of displaying an image directed to a plurality of viewpoints.

摘要： A display device comprising a light source and having an optical waveguide, a louver, an anisotropic scattering sheet, and a transmissive liquid crystal panel disposed along the path of light emitted from the light source. The light-restricting direction of the louver is tilted at an angle α from the Y-axis direction. The value of the angle α is set so that the arrangement direction of moiré created between the louver and the liquid crystal panel approaches the X-axis direction. A plurality of belt-shaped convex portions extending in the Y-axis direction are formed on the surface of the anisotropic scattering sheet, and are configured so that the scattering direction of the light has anisotropy. Specifically, scattering in the X-axis direction is increased, and scattering in the Y-axis direction is reduced. Moiré can thereby be reduced in a display device having increased directivity of the display.

摘要： A display device is provided with a light source, an light-guide plate, a prism sheet, a transparent/scattering state switching element, and a transmissive liquid crystal display panel. In the transparent/scattering state switching element, two transparent substrates are provided parallel to and separated from each other, and an electrode is provided to the surface of each transparent substrate. A scattering seal member is also provided between external peripheral portions of the transparent substrates, and a PDLC layer is enclosed in a space sealed by the scattering seal member between the transparent substrates. The scattering seal member is endowed with scattering properties whereby incident light is transmitted in a scattered state, and the degree of scattering thereof is equal to the degree of scattering of the PDLC layer during the scattering state.
