Abstract: The present invention relates to a display device comprising a substrate, a display module, a lenticular lens and a glass cap. The display module is attached to the substrate and is used for emitting light. The lenticular lens is disposed above the display module and is used for changing the luminous intensity distribution of the light emitted by the display module. The glass cap is disposed above the lenticular lens and is sealed with the substrate for capping the lenticular lens and the display module. According to the display device of the invention, the disunity of the luminous intensity distribution of the light emitted by the display module in different view angles is improved, which facilitates the color control. The present invention also relates to a method of making a display device with a lenticular lens.
