    • There is provided a crystal resonator (crystal element) in which the probability of chipping occurring in separation is small when there is one supporting section with respect to a frame section of a crystal wafer, and inclined surfaces due to the anisotropy of etching are eliminated. The present invention relates to a crystal resonator manufacturing method such that an AT-cut crystal wafer is etched, a large number of rectangular crystal elements are joined with frame sections by supporting sections, and the crystal elements are mechanically cut away from the frame sections. On both sides of the +X-axis one end section of the crystal element, at least the outer side surface has a planarly tapered projection having a triangular inclined surface with an apex in the −X-axis direction, and the tip end of the projection has processing traces of the etching in the +X-axis direction.

    • An image display device main roughly includes a floating image display unit 1 and a floating image recognizing unit 2. The floating image displaying unit 1 includes a display unit 10 having an image screen 11 for displaying a two-dimensional image, and an image transfer panel 20 located far from the image screen 11, the floating image display unit 1 being to focus light left from the image screen 11 on an image plane 30 in a space to thereby display a floating image, the space being located on one side of the image transfer panel 20 opposite to the other side thereof facing the display unit 11. The floating image recognizing unit 2 is formed of a light-transmissive plate 40 that is light transmissive. The light-transmissive plate 40 has a size that allows all light left from the image screen 11 and focused on the image plane 30 to be passed therethrough. The light-transmissive plate 40 is placed to be obliquely-crossed to the image plane 30.
