1. A biological tissue image display apparatus comprising: memory storing instructions; and one or more processors to execute the instructions to: store a reference image obtained by photographing a prefixed stained sample and a comparison image obtained by photographing another stained sample, which are of substantially identical biological tissues; detect a structure of the biological tissue from the reference image; generate a partial image as an independent image by cutting out a portion from the comparison image that includes the structure detected; store the partial image in association with the structure and the comparison image; output a result screen that includes the reference image and the partial image; store a plurality of comparison images each corresponding to the comparison image; detect a plurality of structures each corresponding to the structure from the reference image, cut out from the plurality of comparison images partial images each corresponding to the partial image including one of the plurality of structures detected, and store the partial images each being in association with the structure and the comparison image; and create a matrix in which identification information of the plurality of structures is arranged along a first axis of the result screen and in which identification information of the plurality of comparison images is arranged along a second axis of the result screen, and arrange the partial images in cells of the matrix in such a way that the partial images including same structures are arranged in the cells whose distances from the second axis are same and the partial images cut out from a same comparison image are arranged in the cells whose distances from the first axis are same, the cells being identified by the structures and the comparison images that are in association with the partial images.
