<p><P>PROBLEM TO BE SOLVED: To provide a colored ink composition for forming a visibility-improving sheet that exhibits excellent contrast even when the sheet is applied to a high-definition display device, wherein the visibility-improving sheet is produced by filling wedge-like grooves disposed in parallel among a plurality of prism portions that can transmit light, with the colored ink composition, and curing the composition to form light-absorbing portions. <P>SOLUTION: The colored ink composition used contains: a transparent ionization radiation-curable resin composition having a refractive index lower than that of the material constituting the prism portions; and colored fine particles having an average particle diameter of 1 to 3μm. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
