Provide is a deformation testing apparatus in which a sign of breakage of a specimen under a deformation test can be detected before an actual breakage. The deformation testing apparatus carrying out a plurality of deformation cycles includes an image capturing means; reference data storing means storing the reference data showing the deformation state calculated based on the reference image data shot by the image capturing means; reference cycle number deformation data calculating means to calculate the reference data; detection cycle number deformation data calculating means to calculate detection cycle number deformation data showing the deformation state based on the detection image data shot at the detection cycle number being larger than the reference cycle number; and change detection means to detect that the deformation caused in the specimen is changed based on the reference cycle number deformation data and the detection cycle number deformation data.

Deformation testing apparatus

A photo-alignment material in which an alignment film can be formed parallel to a vibration direction of light and a tilt angle of the alignment film is easily controlled and a photo-alignment method using the photo-alignment material are provided. A photo-alignment material of the present invention contains a photo-responsive substance having a threshold value of responding light intensity.
