FIELD: electromagnetic protection, in particular, electromagnetic protection of electronic devices, and may be used during engineering of liquid-crystalline displays.
SUBSTANCE: liquid-crystalline display is created with grounded conductive grid, having period of cells within range from 50 to 150 millimeters, positioned inside the illumination block and ensuring efficient screening of electromagnetic noise of liquid-crystalline displays within range of frequencies from 10 to 200 MHz without substantial damage to homogeneousness of illumination. In accordance to the invention, in liquid-crystalline display which includes body, liquid-crystalline light modulator which contains row and column controlling electrodes, illumination device, light source and diffuse plate, between the diffuse plate and the light source a metallic wire is positioned.
EFFECT: creation of a liquid-crystalline display, wherein a screening grid integrated in illumination device allows on one side to efficiently let through the light from illumination device, and simultaneously ensures electromagnetic safety of such a liquid-crystalline display.
