metal screen in a cathode ray monitor which reduces the distortion in the displayed picture
This is usually an invar mask which acts to block the electron beam from striking the wrong phosphors in a CRT The beam passes through holes in the mask to strike the correct phosphor while shadowing neighbouring phosphors It prevents a beam intended to strike a red phosphor from striking a neighbouring green phosphor by causing an electron shadow over the green dot
Inside the color monitor just behind the screen, it is drilled with small holes, each of which corresponds to a triad The shadow mask helps guide the electron beams so that each beam hits only one phosphor dot in the triad
