A large area deposition type additive manufacturing equipment is disclosed. The large area deposition type additive manufacturing equipment includes a light source module, a dynamic photomask module, a raw material tank and a deposition module. The light source module includes a plurality of light emitting members, a light diffusion member, a light enhancement member and a light emitting angle limiter. Light emitted from the light emitting members passes through the light diffusion member, the light enhancement member and the light emitting angle limiter to become a collimated curing light. The collimated curing light travels through a transparent member of the raw material tank and a dynamic photomask module to reach liquid photocurable material in the raw material tank, thereby curing the liquid photocurable material. The angle of emitted light ranges within ±30° with respect to a normal line of an incident plane of the light source module.
