The present disclosure relates to an optical sheet having improved optical properties and minimized surface spots. According to one aspect of the present disclosure, provided is an optical sheet comprising: a first prism sheet which has a plurality of prisms parallel in a first direction formed on one surface thereof; and a diffusion sheet which is positioned at the surface side into which light of the first prism sheet is incident and has a plurality of protrusions formed on the surface facing the first prism sheet.

Optical sheet and backlight unit having same

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.

Optical sheet module and backlight unit having same

Disclosed is an optical sheet assembly comprising: a first optical sheet which comprises a first base film and a first optical pattern formed on the first base film, light being incident on the first base film; a second optical sheet which comprises a second base film and a second optical pattern formed on the second base film, the light exiting from the first optical sheet being incident thereon; and a third optical sheet which comprises a third base film and a third optical pattern formed on the third base film, the light exiting from the second optical sheet being incident thereon, wherein the first to third optical patterns perform light condensing or diffusing function, the first optical sheet is joined with the second optical sheet, and the second optical sheet is joined with the third optical sheet.
