The present invention provides a touch panel having pluralities of projections, each of the projections having a predetermined shape, formed on inner surfaces of a lower substrate and an upper substrate, respectively. The projections being formed in at least two directions with a substantially periodical pitch that is shorter than any wavelength of visible light. The touch panel can also include a lower transparent electrode and an upper transparent electrode formed over the inner surfaces of the lower substrate and the upper substrate having the pluralities of projections, respectively. The cross-sectional area of each of the projections parallel to the outer surface of the lower substrate is configured to decrease continuously from bottom to top of the projection. The same applies to the combination of each of the projections, the bottom and a top thereof, and the upper substrate. Accordingly, this structure reduces the light reflection and diffraction at the boundary between an air space and the transparent electrode, thereby providing a resistive contact-type touch panel or a electrostatic capacitive coupling-type touch panel having high light transmittance.

An illumination device is provided that reduces the amount of light leaked to improves illumination efficiency. Electroluminescent elements are formed on one surface of a transparent substrate. The electroluminescent elements are provided with at least a transparent electrode, a light emitting layer, and a reflective electrode in order from the outgoing surface of the transparent substrate. Concavities are formed on one surface of the transparent substrate and the reflective electrode is formed in the concavities. Alternatively, electroluminescent elements are arranged in a planar configuration, and the intervals between the electroluminescent elements and the intervals between the pixels are set so as not to be equal to each other. Also, the directions in which the electroluminescent elements extend and the directions in which the pixels are aligned are set so as not to be parallel to each other.

A coordinate input device is associated with a liquid crystal display to detect a touch or contact thereon. A transparent board is arranged on the screen of the display to provide a coordinate input surface having a substantially rectangular shape. At least one vibration detector (e.g., a microphone or piezoelectric element) is attached onto the board to detect vibration or sound that occurs when a position input member is brought into contact with the coordinate input surface at an arbitrary input position. The input position is represented as one-dimensional coordinate based on outputs of two vibration detectors, or it is represented as two-dimensional coordinates based on outputs of three vibration detectors. Thus, the manually designated input position is detected and is electronically displayed on the screen of the display. As the position input member, it is possible to use a pen, a fingernail, etc.

An image recording method for an image recording medium is used in an image display apparatus that changes an image on a light valve and changes quantity of light which is incident on the light valve via a light control element according to an input image signal. The image recording method includes accommodating a range of brightness information which an object to be imaged indicates, in an entire range of brightness information which an image recording apparatus can record in the image recording medium; and recording a light-control control signal for controlling the light control element when an image signal is recorded on the image recording medium. The light control element is generated on the basis of the range of the brightness information uniformly expanded, in synchronization with the image signal.
