摘要： An optical switch includes a film consisting of a polymer, a keep plate having a switching through hole and a driver. The film has a core linearly extending therein and a notch extending across a switching portion located halfway in the core. The keep plate holds the film to expose the switching portion at the through hole. The driver is employed for narrowing and separating a gap of the notch, thereby selecting a route of light. The notch is formed by precedently forming a starting groove on the surface of the film and pressing the switching portion with a pressing member from the backside of the starting groove while holding the film with the keep plate thereby causing cleavage.

摘要： An optical switch includes a polymer sheet having an optical waveguide extending linearly therein, keep plates holding the polymer sheet therebetween, and driving means. The polymer sheet has a notch provided to traverse the optical waveguides, and the keep plates each have an opening at a position corresponding to the notch. The opening has an elongated shape along the extending direction of the notch at least on a surface of the keep plate in contact with the polymer sheet. The driving means is for selecting a course of light by switching open and closed states of the notch by pushing and not pushing the polymer sheet via the opening.

摘要： The present invention provides an image display device including an LCD, a polarization switching liquid crystal cell, a birefringent plate, and an eyepiece. The LCD displays an image using a plurality of arrayed pixel locations. The polarization switching liquid crystal cell has a plurality of electrodes incorporated therein and switches the direction of polarization in which light emitted from the LCD is polarized. The birefringent plate varies the optical path of light emitted from the polarization switching liquid crystal cell depending on the direction of polarization. The eyepiece magnifies light representing an image displayed on the LCD. The LCD and polarization switching liquid crystal cell are positioned so that the distance L1 from the eyeballs to the virtual image plane of the LCD and the distance L2 from the eyeballs to the virtual image plane of the polarization switching liquid crystal cell will have the relationship of 1/L2−1/L1≧0.4 D or L2≦200 mm. Otherwise, the birefringent plate or the like is coated with an anti-reflective coating. The image display device thus makes unnecessary streaks or flickers indiscernible and displays an easy-to-see image.
