The invention discloses a light guide fiber board, and a manufacturing method and application of the light guide fiber board. The light guide fiber board is very thin and light and convenient to use, the light transmitting area of the light guide fiber board is convenient to machine, structural components of which the outer diameter is below 3mm can penetrate through the light guide fiber board without any obstacle, rivets, screws and other structural components can be avoided, more anti-dazzling screens are not required to serve as auxiliary materials, and cost is lowered. When a larger avoiding area is needed, corresponding empty positions are reserved when weaving is carried out, and no auxiliary materials need to be additionally arranged. The light guide energy consumption can be lowered remarkably.
