PROBLEM TO BE SOLVED: To provide an evaluation method of a display device, which appropriately evaluates a display property of the display device. SOLUTION: A color difference ΔEi as a measurement value is acquired concerning the display device 1 to be evaluated. A detection limit value color difference ΔEk, where luminous factor with respect to color change is considered, is determined with use of a subjective evaluation result of color difference obtained for the display device 1. A high color reproduction evaluation number HR is determined with use of the color difference ΔEi and the detection limit value color difference ΔEk. The display property (a color reproduction property, a viewing angle property, and an illumination environmental property, etc.) of the display device 1 are evaluated with use of the high color reproduction evaluation number HR. Thus, objective display property evaluation which further matches human senses is achieved compared with a conventional manner. COPYRIGHT: (C)2011,JPO&INPIT

PROBLEM TO BE SOLVED: To maintain display for a long period of time and shorten time for holding up a noncontact IC card to a reader/writer. SOLUTION: In the noncontact IC card 1, a rectifying circuit 17 rectifies electromagnetic waves acquired via an antenna 10 to convert into a direct-current voltage, and an electric double layer capacitor 18 rapidly accumulates the electric power acquired by the conversion. Then, the electric double layer capacitor 18, by using the electric energy, operates the circuit of modulation/demodulation circuit 11, CPU 12, memory 13, controller IC 14, driver IC 15 and the like, and rewrites information to be displayed on a display element 16 using a cholesteric liquid crystal, a ferroelectric liquid crystal or the like.

PROBLEM TO BE SOLVED: To provide a screen for projection for obtaining a clear image without being influenced by a projection environment, and to provide its manufacturing method. SOLUTION: A polarizing plate 14 is provided on the surface of the screen. When excessive light except for projection light enters, reflection of light which is not matched with a polarizing face of the polarizing plate out of the excessive light is suppressed, and the excessive light except for the projection light is hardly mixed in an image. In addition, even when an intensity of output of laser light of each color emitted as the projection light from a laser oscillator of a projector, the clear image can be obtained, thereby saving can be saved.
