Abstract: It is an object of the present invention to improve mechanical durability of a portable display device using cholesteric liquid crystal with a memory function such as a non-contact IC card. A display element comprising two substrates 1 which oppose each other and a display portion (liquid crystal) 2 which is sandwiched by the substrates 1, comprises a wall structure 3 bearing a substrate on portions other than the display portion 2, in which the wall is perpendicular to the substrate 1 and a surface perpendicular to the wall is adhered to the substrate 1. Further, in the above display element, an area of the surface which is adhered to the substrate 1 is larger than an area of a surface of the display portion 2 which faces the substrate 1.

Abstract: In an IC card, cholesteric liquid crystal layers reflecting red light and a cholesteric liquid crystal layer reflecting blue light, in a planar state, are laminated, and a voltage is respectively applied to the laminated cholesteric liquid crystal layers, to change the orientation of the cholesteric liquid crystals between the planar state and a focal conic state, so as to transmit or reflect light, thereby displaying predetermined information.

Abstract: A setting of a logical state in an integrated circuit is changed, a plurality of measurement patterns which are used in a quiescent power source current test of the integrated circuit are formed, an internal state value 0/1 of each net at the time when the measurement patterns are supplied by a simulation of the integrated circuit is derived, and further, a pass or fail test result is obtained every measurement pattern by the quiescent power source current test in which a plurality of measurement patterns were supplied to the integrated circuit determined to be a defective device. A state value variable in which the internal state values of all measurement patterns have been stored every net and a test result variable in which the pass or fail test result has been stored every measurement pattern are formed on the basis of those measurement patterns, internal state values, and test results.
