摘要： A parallax barrier device includes a pair of transparent-electrode substrates each provided with a transparent electrode. A barrier light-shielding part and a light-transmitting part are formed in a gap between the pair of transparent-electrode substrates. A liquid crystal layer is formed in the barrier light-shielding part. A resin layer having the property of transmitting light is formed in the light-transmitting part. The barrier light-shielding part separates light for a first image viewed from a first direction and light for a second image viewed from a second direction different from the first direction. The light-transmitting part transmits the light for the first image and the light for the second image.

摘要： An area sensor and an area-sensor-equipped display device are provided which can clearly discriminate between the presence and absence of a finger or input pen touching a panel surface. A liquid crystal display device (100) of the present invention includes: a liquid crystal panel (position detecting section) (20), provided with a plurality of light sensor elements (30) that detects the intensity of received light, which detects the position of an input through detection of an image on a panel surface (detector surface) (100a) by the light sensor elements (30); and a reflectance changing section (45), provided on that side of the liquid crystal panel (20) which faces the panel surface (100a), which effects a change in reflectance of light when pressure is applied to the panel surface (100a). The liquid crystal display device includes: an infrared light blocking filter (90) and an ultraviolet light blocking filter (40a), both provided on that side of the reflectance changing section (45) which faces the panel surface (100a), which do not transmit infrared light and ultraviolet light, respectively; and visible light blocking filters (31) provided on those respective sides of the light sensor elements (30) which face the panel surface (100a), which do not transmit visible light.

摘要： A viewing angle control element of the present invention contains transparent regions 23 having a transmittance T1 and light shield regions 24 capable of switching between a transmittance T2 and a transmittance T3 which is less than T1 and T2 according to an external signal. Each of the transparent regions 23 and the light shield regions 24 is positioned opposite to one of pixels. Displays are produced at or close to the original brightness of the image display element in wide viewing angle mode, whereas in narrow viewing angle mode, light transmission is limited to achieve narrow viewing angles. This is in contrast with other viewing angle control elements which produce displays at or close to the original brightness of the image display element in narrow viewing angle mode, whereas in wide viewing angle mode, light is diffused or otherwise modified to achieve wide viewing angles. Thus, the viewing angle control element is capable of achieving both wide viewing angles and narrow viewing angles, and still preventing image quality deterioration at wide viewing angles due to decreased brightness of the image display element.
摘要翻译：本发明的视角控制元件包含具有透射率T1的透明区域23和能够根据外部信号在透射率T2和小于T1和T2的透射率T3之间切换的遮光区域24。透明区域23和遮光区域24中的每一个与像素之一相对定位。显示器以广视角模式产生在图像显示元件的原始亮度处或接近原始亮度，而在窄视角模式下，光透射被限制以实现窄视角。这与以窄视角模式产生图像显示元件的原始亮度或接近的显示器的其他视角控制元件相反，而在宽视角模式下，光被漫射或以其他方式修改以实现宽视角。因此，视角控制元件能够实现宽视角和窄视角，并且由于图像显示元件的亮度降低，仍然防止在宽视角下的图像质量劣化。
