发明名称 DISPLAY MEDIUM, DISPLAY DEVICE AND REVERSIBLE DISPLAY BODY USING THE SAME
摘要 PROBLEM TO BE SOLVED: To provide a display medium producing more brilliant display, and a display device and a reversible display body using the same. SOLUTION: (1) In the display medium consisting of a display cell and a display composition 10 incorporated into the display cell, the display cell consists of a substrate 1 with an electrode 2 and a homogeneously aligning liquid crystal alignment layer disposed on the electrode surface on the one surface side thereof and a transparent substrate 4 with a transparent electrode and a homeotropically aligning liquid crystal alignment layer disposed on the electrode surface on the one surface side thereof. Furthermore, the display composition 10 is composed of a negative type liquid crystalline composition 8, a negative type dichroic dye 9 and electrophoretic particles 7 with color tone different from that of the dichroic dye. (2) The display device comprises the display medium and a writing device, which are made to be mutually attachable and detachable so as to be in proximity to each other at least in writing. A plurality of signal electrodes and scanning electrodes are mounted on the writing device wherein switching elements to apply an electric field to the display medium corresponding to a picture signal exist on intersections thereof. Thereby the display medium is constructed so as to display a picture. COPYRIGHT: (C)2004,JPO
