Disclosed are a light guide lens (2), a light source module containing the light guide lens (2), and a display device. The light guide lens (2) contains a main body (21) and a plurality of micro-structures (22). The main body (21) has a light incident surface (211) and a light emergent surface (212) on the opposite side of the light incident surface (211). The micro-structures (22) are formed on the light incident surface (211), and at least some of the micro-structures extend radially from a central point. The micro-structures (22) can guide light rays emitted from a light source (3), and after several instances of total reflection inside the main body (21), the light rays are emitted from the light emergent surface (212) at a relatively large angle, thereby increasing a light emergent angle of the light guide lens (2). Moreover, due to the guiding effect of the micro-structures (22), the light rays can be emitted from the light emergent surface (212) at a relatively large angle and in a relatively broad range without increasing the width of the main body (21), thereby effectively reducing the width and light mixing distance of the light guide lens (2).
