Manufacturing example 2
2-1. Optical stratified Produce
On the triacetylcellulose film having a thickness of 40 탆, the composition for forming a photoluminescence layer of Production Example 1-1 was dried and then applied to a thickness of 5 탆. Thereafter, the resultant was dried at 70 DEG C for 2 minutes, and irradiated with UV at a total amount of 400 mJ / cm < 2 > to form a luminous layer, thereby producing an optical laminate.
2-2. Optical stratified Produce
An optical laminate was prepared in the same manner as in Production Example 2-1, except that the composition for forming a luminous layer in Production Example 1-2 was used.
2-3. Optical stratified Produce
An optical laminate was prepared in the same manner as in Production Example 2-1, except that the composition for forming a photoluminescence layer of Production Example 1-3 was used.
2-4. Optical stratified Produce
An optical laminate was prepared in the same manner as in Production Example 2-1, except that the composition for forming a photoluminescence layer of Production Example 1-4 was used.
2-5. Optical stratified Produce
An optical laminate was prepared in the same manner as in Production Example 2-1, except that the composition for forming a luminous layer in Production Example 1-5 was used.
2-6. Optical stratified Produce
An optical laminate was prepared in the same manner as in Production Example 2-1 except that the composition for forming an antireflection layer of Production Example 1-6 was used.
2-7. Optical stratified Produce
An optical laminate was prepared in the same manner as in Production Example 2-1 except that the composition for forming a hard coat layer of Production Example 1-7 was used.
Example And Comparative Example
And the optical laminate as shown in Table 1 below was bonded to the cover window of a 55-inch LED TV (UV55ES800F, Samsung Electronics). A laser pointer for outputting a laser beam having a wavelength of 405 nm was attached to the remote controller of the television.
Experimental Example
(1) Checking the visibility of the laser pointer
When the 405 nm laser pointer was irradiated on the television of the examples and the comparative example at an angle of 60 degrees, the visibility of the laser pointer on the front face of the television was evaluated in the power on / off state, respectively.
&Amp; cir &: The light of the laser pointer is brightly recognized.
A: The position of the laser pointer can be recognized.
X: The position of the laser pointer is not confirmed.
(2)? SCE (%) Measure
The scattering reflectance of the optical stacked body was measured in an SCE mode with an integral spectrophotometer (cm-3700d, Konica Minolta) after attaching the back surface of the optical stacked body manufactured in Production Example 2 to a blackboard.
Since the emitted light is emitted in all directions, the light is measured even in the SCE mode and appears as a scattering reflectance.
At this time, in order to eliminate the possibility that the scattering reflectance may be increased due to the scattering reflection value of the antiglare film itself, the scattering reflectance of the light emitting wavelength and the scattering reflectance (scattering reflectance of the film itself) The luminescence was confirmed by the difference.
If the ΔSCE (%) was more than 0.2%, the laser pointer could be visually recognized easily on the panel.
(3) Hayes (%) Measure
The haze of the optical stack prepared in Production Example 2 was measured with a haze meter (HZ-1, manufactured by SUGA).
Referring to Table 2, the optical stacking structures 2-1 through 2-5 had a high ΔSCE of 0.63 to 1.9%, which was excellent in the visibility of the laser pointer, and the haze was also superior to that of the comparative example. Accordingly, the display device including these optical stacks has excellent visibility of the laser pointer in the power off state, and is excellent without deterioration in visibility even at power-on.
However, in the optical stacks of Production Examples 2-6 and 2-7, the visibility of the laser pointer was lowered to 0% of ΔSCE, and the display devices of Comparative Examples 1 to 3 were not visually recognized in the power on / off state.

And a remote controller having a laser pointer for outputting a laser beam having a wavelength range including an excitation wavelength range of the optical luminescence material to induce light emission in the optical luminescence layer.
