The LCD display has radiation, but is very low.
The principle of radiation is that current produces magnetic field. The magnetic field produces electric field. The electric field then generates magnetic field. This infinite cycle is the source of current. So as long as there is current, there is radiation. However, LCD displays do not have high-voltage coils of ordinary monitors, so the radiation is very low.
LCD monitors are much smaller than flat monitors. Because it does not have a high-voltage circuit, it does not require a high-speed electron beam to bombard the fluorescent screen, so there are no rays such as β and γ, but high-frequency radiation still exists.
