发明名称 DIAPHRAGM OPTICAL ELEMENT FOR CAMERA AND MANUFACTURING METHOD THEREFOR
摘要 PROBLEM TO BE SOLVED: To provide a diaphragm optical element for a camera, which can continuously adjust light quantity and also perform focus control and to provide a manufacturing method for the diaphragm optical element. SOLUTION: The diaphragm optical element for the camera is provided with: transparent electrode layers 6a, 6b, 6c, 6d, 7a, 7b, 7c, 7d having prescribed patterns and a liquid crystal alignment film layer 8, the liquid crystal alignment film layer 8 being arranged between a pair of glass substrates 2, 3 which are arranged oppositely to each other: and a liquid crystal layer 4 containing a dichromatic coloring matter and a chiral agent. Alternatively, the diaphragm optical element is provided with: a first glass substrate 3 with the transparent electrode layers 7a, 7b, 7c, 7d having prescribed patterns and an electrochromic film layer 12; a second glass substrate with the transparent electrode layers 6a, 6b, 6c, 6d having prescribed patterns and arranged opposite to the electrochromic film layer 12; and an electrolytic layer 11 arranged between both the glass substrates 2, 3. The transparent electrode layers 6a, 6b. 6c, 6d, 7a, 7b, 7c, 7d are provided with a plurality of parts arranged concentrically on the glass substrates. COPYRIGHT: (C)2007,JPO&INPIT
