Abstract: For suppressing a deterioration of display quality due to a luminance defect, a display device, a method of correcting a luminance defect and a luminance defect corrector are provided. The display device includes a first substrate (SUB1) having gate lines (GL), data lines (DL), pixel electrodes (PIT), and a common electrode (CIT) on a first glass substrate (GB1), and a second substrate (SUB2) having a plurality of optically transparent parts (CF) and a light shield part (BM) on a second glass substrate (GB2). The first or second glass substrate (GB1) or (GB2) contains a dimmer (10) including a plurality of dimming regions (20) that reduce the transmission of light. The dimmer (10) is formed to be superimposed on a trapped foreign matter (33) in plan view. This reduces the transmission of light from the luminance defect to suppress a deterioration of display quality.
