A light guide plate (1), a liquid crystal display module, and a terminal device are disclosed, where the light guide plate (1) includes: a light guide plate substrate (11), including a light inlet surface (112) and a light outlet surface (113), where a first groove (111) is disposed on the light guide plate substrate (11), and is configured to accommodate a light emitting portion (21) of a first light source (2), and a bottom surface of the first groove (111) forms the light inlet surface (112); and a light reflection layer (12), disposed on a part of an outer surface of the light guide plate substrate except the light inlet surface (112) and the light outlet surface (113), where light emitted from the first light source (2) enters the light guide plate substrate (11) through the light inlet surface (112), and is refracted by the light reflection layer (12), so that the light emitted from the first light source (2) comes out through the light outlet surface (113). |
