    • A surface-spintronic device operating on a novel principles of operations may be implemented as a spin conducting, a spin switching or a spin memory device. It includes a magnetic atom thin film (13) layered on a surface of a solid crystal (12) and a drain and a source electrodes (14) and (15) disposed at two locations on the magnetic atom thin film, respectively, whereby a spin splitting surface electronic state band formed in a system comprising said solid crystal (12) surface and said magnetic atom thin film (13) is utilized to obtain a spin polarized current flow. With electrons spin-polarized in a particular direction injected from the source electrode (15), controlling the direction of magnetization of the magnetic atom thin film (13) allows switching on and off the conduction of such injected electrons therethrough. Also, with the use of the magnetization holding function of the magnetic atom thin film (13), it is possible to realize a spin memory device that can operate to write information on controlling the direction of magnetization of the magnetic atom thin film (13) and that can operate to read information on detecting the state of conduction or nonconduction between the source and drain electrodes (15, 14).

    • A microlens array is provided on a light-outgoing side of a monochromic LCD element having a plurality of pixels each corresponding to any one of the three colors R, G, and B. Microlenses of the microlens array respectively correspond to pixel groups each of which is composed of three pixels corresponding to the three colors R, G, and B, respectively. Light fluxes having passed through the microlens array are converged at an entrance pupil position of a projection lens by a field lens and form pixel enlarged images corresponding to the colors R, G, and B. At the entrance pupil position, there is provided a color filter having color regions which respectively correspond to the colors to which the pixel enlarged images correspond. With this arrangement, it is possible to make a diverging angle smaller, at which light passing through the LCD element and the microlens array and being converged on the projection lens by the field lens is diverged. Therefore, there is no need to make the projection lens have a great diameter. As a result, it is possible to provide a projection-type color LCD device having a single-panel arrangement which can be produced at lower costs.
