DISPLAY DEVICE

The present invention suppresses cracking of a cover member. This display device 1 includes: a bottom member 5; a display panel 3 provided on the bottom member 5; side wall members 8b and 8c provided around the display panel 3; and a glass cover member 2 provided on the display panel 3 and the side wall members 8b and 8c and having a thickness tcg of 0.3-0.7 mm. When the orientation from the bottom member 5 toward the cover member 2 is defined as a first orientation in the thickness direction of the cover member 2, the cover member 2 has a first main surface 2A on the first orientation side, a second main surface 2B on the opposite side to the first main surface 2A, and an end surface 2C connecting the first main surface 2A and the second main surface 2B. When a parameter A is a value represented by formula (1), a parameter B is a value represented by formula (2), a parameter C is a value represented by formula (3), a parameter D is a value represented by formula (4), and a parameter T is a value represented by formula (5), the parameter T is less than 0.
