The reflective polarizing film 600 may be referred to as a Dual Brightness Enhancement Film (DBEF). The reflection type polarizing film 600 may selectively transmit light or reflect light according to the wavelength of light. Through this process, the amount of light blocked by the polarizing film disposed on the display panel 100 can be reduced by passing light having a predetermined wavelength and reflecting light having a different wavelength, thereby improving brightness.
The vertical / horizontal prism sheets 610 and 620 can improve the brightness of the image displayed on the display panel 100 by controlling the path of the light so that the incident light proceeds toward the display panel 100.

As a result, material consumption due to defects is reduced, so that the manufacturing cost can be reduced.
As described above, when the mother substrate 210 is divided into a plurality of substrates 211 to 214, it may be preferable to dispose a connector (not shown) on each of the substrates 211 to 214.
The connector may be electrically connected to at least one light source 220 disposed on each substrate 211-214. Although not shown, such a connector may electrically connect an external driving circuit to the light source 220 so that a driving voltage supplied to the driving circuit is supplied to the light source 220.
When the mother substrate 210 is divided into a plurality of substrates 211 to 214, a plurality of substrates 211 to 214 are arranged in parallel and then a reflective layer (not shown) is formed on the upper surface of the plurality of substrates 211 to 214, Can be arranged.

That is, an air gap 700 may be provided between the optical layer 110 and the light source 120.
As in the case of FIG. 25, the optical layer 110 may further include a diffusion plate 630.
The diffusion plate 630 may be positioned between the prism sheet and the frame 1600.
The diffusion plate 630 can diffuse light emitted from the light source 220 to prevent light from concentrating on a specific region. The light entering the diffusion plate 630 is scattered while passing through the diffusion plate 630, so that the screen of the display panel 100 can maintain a uniform brightness.
The arrangement order of the reflective polarizing film 600, the vertical / horizontal prism sheets 610 and 620, and the diffuser plate 630 in the optical layer 110 may be changed.
