| description | A light source module includes a light guide plate, a light source, a first prism sheet, a second prism sheet and a third prism sheet. The light guide plate includes a light emitting surface, a bottom surface opposite to the light emitting surface and a light incident surface connected to the light emitting surface and the bottom surface. The light source is disposed at the light incident surface of the light guide plate and adapted to emit a light beam into the light guide plate through the light incident surface. The first prism sheet is disposed on the light emitting surface of the light guide plate and includes a plurality of first prism units. The first prism sheet is located between the light emitting surface of the light guide plate and the second prism sheet, the second prism sheet includes a plurality of second prism units along a first direction. The second prism sheet is located between the first prism sheet and third prism sheet, the third prism sheet includes a plurality of third prism units alon |
