DISPLAY DEVICE

摘要

A display device (300) according to the present invention includes: a high-side potential variable-voltage source (180A) which outputs a high-side output potential and a low-side potential variable-voltage source (180B) which outputs a low-side output potential; an organic EL display unit (310) in which pixels are arranged; a high-side potential difference detecting circuit (170A) which detects a high-side potential applied to a pixel (111M A ) and a low-side potential difference detecting circuit (170B) which detects a low-side potential applied to a pixel (111M B ); a high-side potential voltage margin setting unit (175A) and a low-side potential voltage setting unit (175B) which regulate the output potential of the high-side potential variable-voltage source (180A) and the low-side potential variable-voltage source (180B) to set a potential difference between the high-side potential of the pixel (111M A ) and a reference potential to a predetermined potential difference and set a potential difference between the low-side potential of the pixel (111M B ) and a reference potential to a predetermined potential difference; and a signal processing circuit (165).
