<p><P>PROBLEM TO BE SOLVED: To provide an optical filter capable of suppressing the occurrence of color unevenness and providing high-quality images. <P>SOLUTION: A multilayered optical filter 10 arranged on an observer side than an image source 5 and adapted to emit light to the observer side by controlling incident light from the image source side, includes a base material layer 11, an optical functional layer 12 laminated on the base material layer, and an adhesive layer 23 laminated on a surface of the optical functional layer, which is the opposite side of the base material layer. The optical functional layer includes light transmitting parts 13 arranged side by side along the sheet surface so as to be capable of transmitting light, and light absorbing parts 14 arranged side by side between the light transmitting parts so as to be capable of absorbing light. In a cross section in a sheet thickness direction, the light absorbing part has a dent 17 having a curved line shape or a folded line shape on the adhesive layer side. Refractive indexes of the light transmitting part, the light absorbing part and the adhesive layer are substantially the same with each other. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
