Reciprocal space map of specific sample locations is generated based on the sample images acquired by irradiating the sample with a charged particle beam at multiple incident angles. The incident angles are obtained by tilting the charged particle beam and/or the sample around two perpendicular axes within the sample plane. The reciprocal space map of a selected sample location is generated based on intensity of pixels corresponding to the location in the sample images.

A conductive film is provided on the display unit such that the wiring patterns of the two wiring portions overlap with the pixel array patterns of the display unit.
