A display panel test apparatus includes: an image pickup part which picks up an image from a target display panel; a jig including a receiving part which receives the target display panel, a fixing part which fixes the image pickup part, and an adjusting part which adjusts an image pickup angle of the image pickup part; a pattern generating part which provides the target display panel with a test pattern; a defect extracting part which analyzes test image data provided from the image pickup part using a defect extracting algorithm and extracts display defect information, where the defect extracting algorithm includes different settings corresponding to different types of display defects; and a control part which generates evaluated data corresponding to a viewing angle of the target display panel using the image pickup angle of the image pickup part and the display defect information.
