Embodiment Construction

[0042] specific implementation plan

[0043] Hereinafter, an optical film and a light emitting device including the optical film according to the present invention will be described in detail with reference to the accompanying drawings.

[0044] Figure 4 is a perspective view of an optical film according to a first embodiment of the present invention, and Figure 5 yes Figure 4 Front cross-sectional view of the medium optical film.

[0045] As shown in these figures, the optical film 10 according to the first embodiment of the present invention has a structure in which at least one surface of a substrate 11 is formed with a plurality of optical patterns 12 that perform a series of optical actions on incident light. And let the light go away.

[0046] The base 11 is made of a light-transmitting material through which light in the visible range can smoothly pass. For example, the substrate 11 may be made of any one of polycarbonate, PVC, PP, PE, PS, PET, and acrylic polym...

Abstract

The present invention relates to an optical film formed with a plurality of optical patterns having peak and valley portions and a lighting device having the optical film. Pitches of the optical patterns, heights of the peak portions and depths of the valley portions are irregular, and plan and side structures of the optical patterns have a non-linear non-symmetrical arrangement structure in which the peak and valley portions are irregularly bent. According to an optical film and a lighting device having the same of the present invention, a moire phenomenon can be prevented in advance, abrasion resistance can be improved, optical defects such as scratches cannot be observed with the naked eye, a wet-out phenomenon can be prevented, and a viewing angle can be broadened.

Description

technical field [0001] The present invention relates to an optical film and a light-emitting device comprising the optical film, and more particularly, to an optical film having improved optical characteristics and a light-emitting device comprising the optical film, in which an optical pattern formed is non-linear, non-linear Symmetrical and irregular, so the moiré phenomenon can be prevented, abrasion resistance can be improved, and even when optical defects such as scratches are generated, the optical defects cannot be observed with the naked eye, and optical coupling (wet-out) can be prevented phenomenon, and can broaden the perspective. Background technique [0002] Widely used in display devices such as mobile phones, notebook computers, LCD monitors, and flat-panel TVs, images are displayed on a panel using light emitted from a backlight unit. [0003] The backlight unit of the display device includes a light source for emitting light, a light guide plate for allowin...
