Patent ID: 8902499

Claim:
A display module, comprising: a first substrate and a second substrate facing each other; a liquid crystal layer located between the first and second substrates; a first polarizer laminated on the first substrate; and a conversion layer laminated on the first polarizer, wherein the conversion layer includes a plurality of first films and a plurality of second films in an alternating manner, each of the first films having a first refractive index, and each of the second films being laminated on a lower surface of a corresponding first film and having a second refractive index lower than the first refractive index, and wherein the conversion layer is configured to reflect light with an infrared ray band, a sum of thicknesses of the first and second films is more than at least 10 μm, the first film has a refractive index in the range of 2.5 to 2.9, and the second film has a refractive index in the range of 1.8 to 2.3.
