Abstract: A display device and a display module. The display module includes: a blue LED chip, a yellow phosphor layer and a colour filter. A peak wavelength of a blue light emitted from the blue LED chip is in a range of 460±5 nm. The blue LED chip excites the yellow phosphor layer to emit a white light. The colour filter is disposed outside the yellow phosphor layer, and the white light emitted irradiates on colour filter. Through right shifting the peak wavelength of the blue band emitted from the blue LED chip to about 460 nm to realize the low blue energy and decrease the radiation. The transmittance of blue light of the colour filter is less than 7%, the transmission peak wavelength of blue light is in a range of 440-450 nm. The display module can decrease the energy of the blue band and ensure the display effect.

Abstract: A liquid crystal display device and a reflective display module of the same are disclosed. The reflective display module includes: a first substrate, a reflective layer disposed on the first substrate for reflecting an incident light, and multiple color resists disposed on the reflective layer. Wherein, the incident light enters the reflective layer through the color resist, after the incident light is reflected by the reflective layer, a reflection light is obtained, and the reflection light is emitted out through a same color resist. Through above way, the present invention can avoid the reflection light and the incident light from passing through two different color resists in order to increase reflectivity and eliminating the color mixing.
