Abstract: A biometric device includes an illuminating unit and an imaging module. The imaging module includes an optical angular selective structure and a sensing layer. The light selecting structure includes a micro lens array, a refractive layer and a light shielding layer. The refractive layer is disposed between the micro lens array and the light shielding layer. The micro lens array includes a plurality of lens unit units, and the light shielding layer has a plurality of light passing portions. The sensing layer defines multiple sensing regions which are spaced apart from each other. The light shielding layer is disposed between the refractive layer and the sensing layer. The sensing regions correspond to the light passing portions, respectively. An optical angular selective distance is defined between the light shielding layer and the sensing layer.

Abstract: A photo-imprinting resin composition, a photo-imprinting resin film and a patterning process are provided. The photo-imprinting resin composition includes a novolac resin; a monomer having acrylic group, a polymer having acrylic group or a combination thereof; and a radical type photopolymerization initiator. The novolac resin has a Mw of 500 to 50000. The novolac resin does not react with the monomer having acrylic group nor the polymer having acrylic group described above.
