A dimming device and a dimming apparatus, which relate to the field of flexible dimming device technology. The dimming device includes a dimming film. The dimming film includes a first area (11) and a second area (12), and the second area (12) is arranged surrounding a circumference of the first area (11). The dimming film includes a preset point O and a preset division line M, where the preset division line M divides the dimming film into a first part (10a) and a second part (10b). The first part (10a) satisfies an inequality of A1A2 ≤ OB1 - L1, and the second part (10b) satisfies an inequality of C1C2 ≤ OD1 - L2, where A1 represents a point on an outer contour of the second area (12) that is farthest from the preset point O in the first part (10a); A2 represents an intersection point formed by a line segment OA1 intersected with an outer contour of the first area (11); B1 represents a point on the outer contour of the second area (12) that is closest to the preset point O in the first part (10a); L1 represents a maximum perpendicular distance between the outer contour of the first area (11) and the preset division line M in the first part (10a); C1 represents a point on the outer contour of the second area (12) that is farthest from the preset point O in the second part (10b); C2 represents an intersection point formed by a line segment OC1 intersected with the outer contour of the first area (11); D1 represents a point on the outer contour of the second area (12) that is closest to the preset point O in the second part (10b); and L2 represents a maximum perpendicular distance between the outer contour of the first area (11) and the preset division line M in the second part (10b). The dimming device can alleviate the edge wrinkles.
