A transmissive type liquid crystal display panel includes a liquid crystal cell including a liquid crystal material layer, a pair of polarizers between which the liquid crystal layer is disposed, for polarizing incident light, and an optical system disposed on a front surface of the display cell, for refracting light transmitted through the liquid crystal cell in an oblique direction having a good contrast image to an observer.

A liquid crystal display with multiplex capability enhanced by decreasing the hysteresis characteristic of the liquid crystal. The hysteresis characteristic of the crystal is reduced by fixing an angle of twist of the liquid crystal molecules in the range of 270 to 315 degrees, by setting a birefringence (.DELTA.N) of the host molecules at less than or equal to 0.14 and by having a crystal layer thickness (d) of less than or equal to 7 .mu.m (.DELTA.n.multidot.d
摘要:
A retardation compensation element (32, 32a) has a first optical anisotropic layer (42) that functions as a negative C-plate, and a second and a third optical anisotropic layers (43, 44) that function as positive O-plates. VA mode liquid crystal molecules (37) tilt at an azimuth angle of 45 degrees and a polar angle of 5 degrees when no voltage is applied thereto. The second and third optical anisotropic layers have optical axes respectively at an angle of −105 degrees and +105 degrees from the tilt direction of the liquid crystal molecule. The first optical anisotropic layer (42) compensates the retardation of light that enters a liquid crystal layer (38) at an oblique angle while the second and third optical anisotropic layers (43, 44) compensate the retardation of light that enters the liquid crystal layer at a right angle.
摘要:
Red incident light is reflected on a mirror (19) and linearly polarized by a polarizer (26R). Linearly polarized incident light enters a transmissive liquid crystal device (11R), in which oblique incident light is changed into elliptically polarized light. A retardation compensator (27R) between the liquid crystal device (11R) and an analyzer (28R) has an inorganic form birefringence layer. The retardation compensator (27R) yields birefringence effect to change elliptical polarized light into linearly polarized light. Linearly polarized light from the retardation compensator (27R) can pass the analyzer (28R) without decreasing intensity, and enters a color recombining prism (24). The liquid crystal device (11R) may have the inorganic form birefringence layer. Retardation in green and blue light is also compensated in the same manner. Red, green and blue image light, mixed in the color recombining prism (24), is projected onto a screen 3 by a projection lens system (25).

A relay server computer adds control code to background contents to generate web data for display engagement, and sends the generated web data to every client computer. The control code becomes a controller by executed on the client. When an object such as image is pasted on the background contents displayed in an engaged fashion, the controller detects the event occurred by pasting, and sends the information indicating the event to the other clients via relay server. Consequently, the screen with the object being pasted is displayed in an engaged fashion among all clients. The object can be moved, modified, or deleted.
摘要:
Three retardation compensators are provided for compensating the retardation of liquid crystal devices for red, green and blue light, respectively. Each of the retardation compensators is composed of plural high and low refractive index thin film layers alternately layered on a substrate. Because of the difference in the wavelength dependences of the liquid crystal device and the retardation compensator, the retardation R2 of the retardation compensator becomes much larger than the retardation R1 of the liquid crystal device in short wavelength region of the visible band. In order to match the retardation, the thickness of the retardation compensator for blue light is smaller than those for red and green light.

In the storage structure for a personal watercraft, a first hatch cover is installed in front of a handlebar in an openable and closable fashion with respect to a deck and a second hatch cover is installed on the first hatch cover in an openable and closable fashion with respect to the first hatch cover. A first storage area is formed inside the first hatch cover and a second storage area is formed inside the second hatch cover.
摘要:
A liquid crystal display device has an arrangement of a plurality of pixel display regions each including a plurality of divided pixels, and is capable of effecting display with a large number of gray levels. Each of the divided pixels is displayed individually and selectively with at least two gray levels. The liquid crystal device further includes pixel electrodes for individually and selectively enabling the divided pixels, and a gray level setting circuit for controlling the sum of the areas of the enabled divided pixels, thereby setting the gray levels of the pixels. In this device, one pixel display region includes n divided pixels and if each pixel can be displayed with m gray levels, the areas of the pixels are set to form a geometric progression using m as a common ratio, whereby display with m.sup.n gray levels for one display region can be effected with high precision.
