Display device and manufacturing method thereof

A manufacturing method of a display device, comprising:

• providing a backlight unit;
• and
• providing a display panel disposed corresponding to the backlight unit,
• wherein an emission spectrum is performed by the display device in a white image of highest grey level,
• wherein the emission spectrum comprises a first sub emission spectrum ranging from 380 nm to 478 nm and a second sub emission spectrum ranging from 479 nm to 780 nm, and the first sub emission spectrum has a maximum peak wavelength greater than or equal to 453 nm,
• wherein an integral value of the first sub emission spectrum multiplied by a blue light hazard weighting function from 380 nm to 478 nm is defined as a first integration, and an integral value of the second sub emission spectrum multiplied by an eye function from 479 nm to 780 nm is defined as a second integration, and
• wherein a ratio of the first integration to the second integration is in a range from 40% to 65%.
