Title:
線の鋭さが改善した液晶筆記装置
Document Type and Number:
Japanese Patent JP7111361
Kind Code:
B2
Abstract:
A liquid crystal writing device with enhanced line acuity includes the following features. Included is a front writing surface. A liquid crystal layer includes a dispersion of cholesteric liquid crystal and polymer, wherein a reflectance of the cholesteric liquid crystal changes in response to pressure applied to the front writing surface so as to form an image on the liquid crystal layer. The liquid crystal layer is disposed between electrically conductive layers. A second of the electrically conductive layers is more distal from the front writing surface than a first of the electrically conductive layers is from the front writing surface. A backing supports the pressure applied to the front writing surface. An adhesive layer is disposed between the second of the electrically conductive layers and the backing. A line acuity of the image has a value of not more than 3.0 determined according to the Line Acuity Measurement Method of this disclosure.
