Abstract
An optical functionality sheet provided with microlenses and a functional film (reflective film or light-blocking film/light-diffusing layer), with the above described functional film formed upon a patterned transparent conductive film. Thereby, self-alignment exposure using microlenses is made possible, and an optical functionality sheet with good directivity with respect to incident light, and good angle of visibility characteristics, can be realized.
