| description | A display device includes a display panel and a backlight assembly. A light source unit of the backlight assembly includes a light source board including a conductive pattern, a light emitting chip on the light source board and electrically connected to the conductive pattern, a wavelength conversion member covering the light emitting chip and converting a wavelength of light emitted from the light emitting chip; and diffusion particles in the wavelength conversion member. The light emitting chip includes a rear surface facing the light source board, a top surface opposite to the rear surface and a side surface connecting the rear surface to the top surface. A density of the diffusion particles in the wavelength conversion member at the top surface of the light emitting chip is greater than a density of the diffusion particles in the wavelength conversion member at the side surface of the light emitting chip. |
