    Abstract: The present invention relates to an optical sheet module that is arranged on one side of a light source and that transfers light upwards. Provided is an optical sheet module comprising: a base film sheet which transmits light; a light entrance surface which is formed in a lower part of the base film, through which light emitted from the light source is transmitted and through which the light enters internally; a light reflection surface which is located in the direction opposite to the light entrance surface, and which reflects light that enters through the light entrance surface and transfers the same upwards; and a light collection part in which a light collector unit having a cross-sectional area that decreases towards a lower part thereof is arranged consecutively and repetitively along the direction in which light is emitted from the light source, wherein the light collection part has a cross-sectional trajectory according to a vertical direction of the light reflection surface being formed retracting in an internal direction with reference to a virtual straight line trajectory from the lowest part to the highest part.
