Provided is a display device having a viewing angle changing function, which is capable of preventing leakage of information displayed on a display screen even when there is a fault generated in changing the viewing angle. The image display device including a viewing angle changing element capable of changing a wide vision display and a narrow vision display and including a display element is provided with a detection element which detects a fault generated in the viewing angle changing element and a module for changing to a narrow vision display when there is a fault based on a detection value of the detection element. For example, when there is a fault, a transparent heater is operated to heat a liquid crystal layer to set a transparent-scattering changing element to a transparent state and forcibly set the display device to a narrow vision display.

A liquid crystal display accommodates a reflective portion with a concavo-convex reflecting pixel electrode for reflecting incident light from the display face side, and a transmissive portion with a transmissive pixel electrode for transmitting light output from the backlight. In a wide viewing angle region, luminance of the reflective portion is greater than the transmissive portion. In other angle regions, luminance of the transmissive portion is greater than the reflective portion. In a wide viewing field mode, the reflective portion and transmissive portion both perform normal display. In the narrow viewing field mode, the transmissive portion performs normal display, while the reflective portion performs cancelling data display, thereby rendering unviewable the display content of the transmissive portion from beyond a certain viewing angle. Thus, a semi-transmissive liquid crystal display device and a portable terminal device is switchable between a narrow viewing field mode and a wide viewing field mode.

A microlouver includes a periodic structure in which a transparent layer and a light absorption layer are alternately disposed with a constant, repetitive period. The range of the exit direction of a light beam passing through the transparent layer is restricted by the light absorption layer. The periodic structure includes a periodic structure portion divided in the direction that intersects the direction in which the transparent layer and the light absorption layer are repeatedly disposed. In the periodic structure portion, between the periodic structures adjacent to each other, there is a difference of 180 degree in the phase of spatial frequency of each periodic structure.

A liquid crystal display panel has a drive substrate and an opposing substrate disposed parallel to each other by way of a seal member provided with a liquid crystal injection inlet. A liquid crystal layer is sealed between the two substrates. Apertures are provided in the portion formed on the periphery of the pixel area of the smoothed film that is formed on the surface of the drive substrate, and an orientation film is formed so that at least part of the peripheral edge portion is positioned inside the apertures. Thereby, the liquid crystal injection time can be reduced and the panel can be set in a narrow frame, and the wiring and peripheral drive circuits are not liable to be damaged.

In a light source device, a row of fibers is provided in which a plurality of optical fibers is arrayed in a single row in parallel fashion separately from each other. A light-direction controller is disposed on one side of the optical fibers, main fibers is disposed above and below the light-direction controller, and a main fiber is disposed at the other end of the row of fibers. Light sources are connected to each of the end portions of the main fibers. Three types of mirrors that mutually differ in direction are formed on the surface of the light-direction controller, light emitted from a main fiber enters the optical fibers by way of a first mirror, and light emitted from a main fiber enters the optical fibers by way of a second mirror.

A liquid crystal display having a wide viewing angle and easily manufactured. The liquid crystal display comprises an upper substrate and a lower substrate, and a liquid crystal material disposed between the upper substrate and the lower substrate. The liquid crystal display has a conductive protrusion disposed on the surface of the upper substrate opposing to the lower substrate. The conductive protrusion is disposed over a scanning electrode line or a signal electrode line and has the same potential as that of the upper electrode. As another structure, each of pixel electrodes on the lower substrate has a smaller area than that of a common electrode on the upper substrate and is covered by the common electrode, and each of the pixel electrodes comprises an electrode portion having approximately symmetrical shape.

The present invention relates to an optical modulating display device (200) such as a liquid crystal displaying device provided with a front-light type planar illuminating device. The above front-light type planar illuminating device allows illuminating light to propagate inside a substrate (1), and is provided with a low refraction layer (3) being lower in refractive index than the substrate (1) and being in close contact with the inner surface of the substrate (1), and with reflection structure (11) on the outer surface of the substrate (1). The optical modulating display device (200) provided with the above front-light type planar illuminating device can ensure a sufficient amount of guide light propagating inside the substrate (1) and reduce non-uniformity in display illumination. And a display apparatus mounting the above optical modulating display device (200) thereon can be reduced in thickness and weight and provide a high quality display.
