Abstract: A manufacturing method of a display apparatus includes providing a backlight unit under a display panel to provide a light to the display panel. The providing of the backlight unit includes disposing a light source on a substrate to emit the light, disposing a mask above the light source, which includes a first opening and a second opening greater than the first opening disposed under the first opening, and providing a transparent resin including a wavelength converting material on the light source through the first and second openings to form a wavelength converting member. A width in a cross section of the wavelength converting member along a direction substantially vertical to the substrate becomes smaller as a distance from the substrate becomes greater.
