The invention discloses a display device. The display device comprises an array substrate and a color film substrate which are connected in a box-facing mode, the surface, facing the array substrate, of the color film substrate is provided with a black matrix, the black matrix is provided with a plurality of opening areas which are distributed in an array mode, a plurality of lenses used for guiding the light directed to a shading area of the black matrix to the opening areas are arranged at the side, opposite to the color film substrate, of the array substrate, a transparent protection layer is arranged on the surface, with the lenses, of the array substrate and covers the lenses, and the surface, opposite to the color film substrate, of the protection layer is flat. The light directed to the shading area of the black matrix is reflected by the lenses to the opening areas so that the total amount of light passing through the opening areas can be increased, the overall light utilization rate of the display device is improved, and the display effect of the display device is improved. Therefore, the display device is high in overall light utilization rate, and good in display effect.
