Abstract

An apparatus for inspecting a display panel includes a light source irradiating light toward a surface of the display panel; a light detector detecting light reflected from a region of interest on the surface of the display panel to generate a captured image; a lens system including at least one lens receiving the reflected light and providing reflected light to the light detector; and an analyzer quantifying a degree of curvature of the region of interest based on a result of comparing modeling data including distribution of reference light intensity for the region of interest with detection data corresponding to the captured image, and determining whether the display panel is defective based on a quantified result.
