    摘要: The present application provides a biometric sensor. The biometric sensor includes a first base substrate; a second base substrate facing the first base substrate; a plurality of photosensors on the first base substrate and configured to detect at least a portion of a light totally reflected by a surface of the second base substrate facing away the first base substrate, thereby detecting a biometric information; a low refractive index layer on a side of the plurality of photosensors distal to the first base substrate; and a high refractive index layer on a side of the low refractive index layer distal to the first base substrate and directly adjacent to the low refractive index layer. The high refractive index layer includes a material having a refractive index higher than a refractive index of a material of the low refractive index layer.
