Abstract
A light source module including an optical film and at least one light source unit is provided. The light source unit and the optical film enclose a space. The light source unit includes a reflecting device, at least one light bar, and a collimated unit. The reflecting device is disposed under the optical film. The light bar includes a plurality of light-emitting elements arranged along a third direction. The collimated unit extends along a direction parallel to the third direction and includes an upper reflective portion and a lower reflective portion. A shortest distance between one end of the lower reflective portion located adjacent to the reflecting device and the optical axis of the light-emitting elements along a second direction is defined as a first half light-emitting width, which is gradually increased along the third direction from a center portion of the collimated unit towards two sides thereof.
