Description

Art field

About books. More specifically, the present invention relates to a display C), a plasma display panel PDP), a brown (CR) display, and the like, and particularly to a high display.

In an image display device such as a CD PP CR display, light may enter the screen from the outside, and this light may be reflected to make it difficult to see the display image. In particular, with the recent increase in screen size and high definition of flat panel displays, it has become increasingly important to solve the above problems. In order to solve such problems, the conventional approach has been taken for displays. For example, the process of making the surface of the various types of display hard coat films used for the polarizing plate in the installation face has been implemented. As a method of managing such a hard dot fill, there are mainly methods in which a child is added to the dot layer to make the surface face (~ 3 and (2). (4, 5) Of these methods, the latter (2) method of surface-facing to form a hard layer is a complicated operation, so the former The mainstream method is to add a child to the hard coat layer to make the surface face, and as a child, it is added to the coating solution for forming the hard coat layer, which has a low hadot fill. From the standpoint of good dispersibility, silica particles are mainly used. 80,950

It is intended to provide excellent brightness, surface quality, transparency, gloss and prevention. In particular, it can be used for very high-definition C and PP like a high-definition spray full-split vision display in recent years, and is intended to provide a high-quality, black-colored image, excellent image quality, and low production.

Up to now, the hard cores disclosed in (1) to (3) above are known, but all of these have low clarity and are very high-definition such as recent high-definition displays or full-spectrum vision displays. It does not achieve that required by PP. In addition, in order to increase the contrast of the image, the actuality has been regarded as important as a new characteristic. For this reason, there is a need for a hard fill that does not impair the blackness even when applied to the screen surface. In addition, in order to obtain high-quality images, there is a need for a hard coat with an appropriate gloss.

Et al. Conducted a study to satisfy all of these properties at the same time, and argued that it could not be achieved only by further adjusting the amount of particles or using particles having a diameter in combination. It came. In other words, in general, if the number of particles in the hard layer is increased or the size of the particles is increased in order to increase the level of the hard coat, the display becomes lower and the display becomes inferior. Become. In addition, it is inferior in blackness. Or reduce the amount of particles, If you do it, it will be inferior to, and it will impair your ability as a hadcot fill.

Furthermore, it has been renewed that depending on the amount of particles, a brighter () is likely to occur on the screen than the surroundings.

As a result of further investigation, it was found that by having a specific shape, it was possible to improve the transparency while maintaining transparency, and that image display using such a, black expression, and image I found out that I was excellent in the process, and completed the clarification.

That is, even if (A) is not laminated on one side), the cloth width (W) plotting the degree of protrusion against the protrusion on the face of (B) is 500 m 50 below Is.

In addition, 60 in terms of

It is 0 0 lower, 0 · 5 upper 3 5 lower, and the hazard B) is average upper 5 lower

C) containing 0 5 5 below and on average 5 60 below) containing 30 50 below

The parts are gathered in the protective section (B), and the organic B (C) and the organic C (C) are under 0 · 5 3 · 0, and the ) On the surface of the cloth plotted the degree of protrusion against the protrusion width W

) And C of the fabric satisfy the following)

23XW)

Even better can be obtained by adopting either of the reflection (E) on the hardware (B). In addition, a display device using the above is included. For the purpose of carrying out the light, the hardware (B), which will be described later, is laminated on at least one side, without A) which will be described later.

In the case of light, it is necessary that the width of the cloth B) is lower than the value width W 50 50 of the cloth in which the degree of protrusion relative to the protrusion is plotted. The value width W of the protruding fabric and the fabric are the half value and the height of the surface profile obtained by the ZYGO product name V e 5022), plotting the projection), CO S) on the horizontal axis by so Po.

When the gW of the cloth is in the above numerical range, the cloth is excellent in transparency, gloss, and prevention, and in the balance between these. In addition, can be reduced. When the price range W is too small, the gloss tends to increase and tends to be inferior to. Also, tends to increase. On the other hand, when the full width at half maximum W is too large, it tends to increase and tends to be inferior in transparency. From this point of view, the full width at half maximum W is more preferably below 5500 and particularly preferably below 700.00.

In addition, in the light, it is preferable that the cloth value width W) plotting the degree of protrusion with respect to the protrusion degree and the cloth CS (s) satisfy the following () on the face (B).

23XW)

If the fabric value width W and the fabric width are in the range satisfying the above (), can be further reduced. In, when the left side is too large than the right side, tends to increase. The fabric is preferably under 5000 Co s) Co S). When the value of the cloth is in the above numerical range, the balance between transparency and gloss is excellent. In addition, can be further reduced. If the amount of cloth is too large, tends to increase. On the other hand, if it is too low, the gloss tends to increase and the effect is low. From this point of view, the protrusion fabric is more preferably 8000 Co s) Co), particularly preferably 0000 Co) Co) on the side of the hardware B), which is the value width W of the protrusion fabric. There is no particular limitation on the method of setting the values of, and fabric to the above values. You can do this by adding a hard coat (Z constant or by using B) and then using the separation. It may also be achieved by performing physical or physical processing. This is because the method of adding specific children can be performed stably and relatively easily.

In particular, the value range W of the protruding fabric and the particularly preferable method for ensuring that the fabric satisfies the above-mentioned conditions are the organic C) and content, inorganic () and content, inorganic) collections described below. As mentioned above, it can be mentioned that the anti-hardware B) is suitable. In particular, it is important that the inorganic D) part is gathered in the protective B). C) Organic of C) when adjusting by D) or by quantity

When the value is increased, the value width W of the protruding fabric tends to decrease, and at the same time, the protruding fabric tends to increase. Increasing the amount of C) tends to increase the protuberance. When the amount of (D) is increased, the fabric width W tends to increase. In order to satisfy the above), it is effective to reduce the amount of organic C. For example, It is effective to reduce the amount to 3 · 5 or less. In addition, T of Hadokoto B and C of organic (C)

It is also effective to reduce C, for example, it is effective to set (C) to 2 4 lower. It is particularly effective to adjust these combinations.

Such an embodiment having a surface waviness component in the face B) is preferable. By adopting such an aspect, it becomes easy to set the value width W of the protrusion fabric to the above-mentioned value, and it becomes easy to form a preferable surface shape in light. The waviness component is different from the sharpness and indicates that it exists gently on the surface of the dot B. According to their observations, such a surface undulation component is presumed to be formed by an assembly of an inorganic (non-inorganic), which will be described later. The size of such a surface undulation component is preferable. More preferably, 0 U 90, more preferably 20 U 85, particularly preferably 30 U, 50 m. By setting the size of the swell component to the above value, the value width W of the protruding fabric may be further set to the above value. Further, the surface roughness component can be easily formed by controlling the size of the inorganic material or the aggregate.

It is preferably below 600 00 in the plane of the bright (B). When 60 is in the above numerical range, the balance between transparency and gloss is excellent. When 60 is too low, the transparency tends to decrease, and the effect is reduced. On the other hand, if 60 is too high, it tends to be inferior to. From such a point of view, it is more preferably 60 2 or less, particularly preferably 7 3 or less. By adjusting the amount of organic C) and () described later, or by adjusting the amount of B (only B), Can be made.

Further, it is preferably lower than 0 · 5 3 5. If it is too high, the transparency tends to be low, and the effect is low. Low is preferred, but generally

For this reason, it is necessary to reduce the amount of particles added to the protective layer and to reduce the particle size, which may cause problems such as easy damage. I prefer the top. From this point of view, the lower limit is more preferably 0 7 2 7, further preferably 0 · 9 upper · 9 lower, and particularly preferably • upper · 6 lower. However, this can be achieved by adjusting the amount of organic (C) and () described later, adjusting the ratio of organic (C), and adjusting the brightness of the organic (C).

Further, it is preferable that the degree in the dark side (B) is higher, more preferably 2.
