    摘要: The present invention provides an apparatus and method for detecting flatness and/or unevenness of a surface of an overcoat layer on a colored pixel layer of a color filter with a high degree of accuracy. The apparatus includes: a light source 34, placed almost directly above the surface of a plate 30, for emitting an emission-line spectrum corresponding to at least one color of coloring particles in a color filter 32; a photo-receiver 36, placed obliquely upward with respect to the surface of the plate 30 and having a spectral sensitivity corresponding to the emission-line spectrum of the light source, for receiving reflected light from the color filter 32 on the plate 30 during inspection; and a detection means 42 for creating a brightness distribution for a color using a color signal output from the photo-receiver 36 as corresponding to its spectral sensitivity to detect the flatness (unevenness) of the surface of an overcoat layer 16.
