To provide a display device capable of reducing the number of analysis results a user should check with respect to analysis results of three-dimensional shape data having a repetition structure, and to provide a display method.

An abnormal value extraction part 13 extracts an evaluation point which satisfies an extraction condition predetermined by value of an analysis result from among a plurality of evaluation points on a surface constructing a three-dimensional shape model. A closed plane grouping part 141 groups evaluation points where values of the analysis results coincide among the evaluation points included in respective closed planes every closed plane comprising the three-dimensional shape model. A similarity grouping part 143 groups, as a similar group, a closed plane group in which: the number of evaluation points included in the respective closed plane groups is the same; and an average value every closed plane group of the values of the analysis results of the evaluation points is within a predetermined closed plane average value alteration allowable range. An analysis result display part 16 displays values of the analysis results to a display picture 50 every similar group of each confirmation item.
