Abstract
A method for testing lifetime characteristics of a display panel in which a plurality of pixels each including a light-emitting element (an organic EL element) are arranged in a matrix, includes: setting a first light-emitting region including a plurality of pixels; setting a non-light-emitting region including all pixels adjacent to the first light-emitting region; setting a second light-emitting region including pixels which are not included in the first light-emitting region and the non-light-emitting region; and testing the lifetime characteristics of the display panel by causing the pixels in the first light-emitting region and the pixels in the second light-emitting region to emit light at different luminance levels without causing the pixels in the non-light-emitting region to emit light.
