Abstract: The present invention relates to a display module comprising: a first panel in which a plurality of pixels composed of a light-emitting unit and a light-transmitting unit are arranged in an array; and a second panel located on the rear surface of the first panel and including a plurality of light-blocking shutters corresponding to the plurality of pixels, respectively, wherein the light-blocking shutters comprise: a diffusion unit having a first thickness; a collecting unit located on one side of the diffusion unit and having a second thickness greater than the first thickness; transparent electrodes located in the diffusion unit and the collecting unit; and a first fluid and a second fluid which are located in the diffusion unit and the collecting unit and do not mix with each other. The first fluid moves between the diffusion unit and the collecting unit according to the voltage applied to the transparent electrodes, and one of the first fluid or the second fluid is transparent and the other is opaque.

Abstract: The present invention can be applied to the technical field pertaining to display devices and, for example, relates to a flat lighting device using a light emitting diode (LED) and a display device including same. The present invention provides a display device including a flat lighting device, wherein the display device may comprise: a light source which emits white light by using a light emitting diode and a yellow phosphor; a red phosphor layer which is disposed on the light source and adsorbs a part of the white light emitted from the light source to emit red light; and a first dichroic filter layer which is disposed on the red phosphor layer and has a reflective pattern reflecting at least a part of the long-wavelength side of the wavelength region of the red light.
