The thermoplastic composition according to the invention for shaped
light-scattering articles, based on a transparent thermoplastic formed
from (meth)acrylic (co)polymer and on light-scattering particles,
comprises polytetrafluoroethylene (PTFE) particles or a mixture of PTFE
particles and particles of a mineral and/or organic substance, these
light-scattering particles having a mean size of 0.5 .mu.m to 200 .mu.m
and a refractive index which differs from that of the transparent
thermoplastic by at least .+-.0.05 and being used in an amount, with
respect to the total composition, of 5 ppm to 2000 ppm by weight.
Application to light display devices and to flat light screens comprising a
sheet obtained from the composition.
