Description

Light emitting device display device{LIGHT EMITTING DIODE DEVICE DISPLAY APPARATUS}

The present invention relates to a light emitting device display device. More specifically, the present invention relates to a light emitting device display device including a polarizing plate having a thin thickness, low reflectance in front and side surfaces and low color change in side surfaces.

In an image display device, it is one of the most important tasks to improve the contrast representing the difference in luminance between the brightest part and the darkest part of the screen. In order to increase the contrast, simply increasing the luminance of the light source can be considered as one method. However, this method has a problem of putting high stress on the device by increasing the power consumption generated by the light-emitting organic material of the organic light-emitting diode (OLED). Therefore, in the organic light emitting diode, it is common to use one polarizing plate to adjust the reflectance of the incident light from the panel.

A polarizing plate provided with a two-sheet type each containing anisotropic material has been proposed. However, in order to reduce the thickness, a single-sheet polarizing plate was developed using a reverse wavelength liquid crystal. However, there is still a limit to the anti-reflection effect in the oblique direction, especially the color change. As an improvement plan, a polarizing plate provided with a positive C plate along with a single sheet has been proposed, but the thickness is increased.

Hereinafter, a light emitting device display device according to an embodiment of the present invention will be described.

Referring to FIG. 1, a light emitting device display device includes a light emitting device panel 100 and a polarizing plate 200 formed on an upper surface of the light emitting device panel 100.

In a light emitting device display device, a pattern retardation layer 210 and a polarizing film 220 are sequentially formed from the light emitting device panel 100. In the light emitting device display device, the above-described polarizing plate 200 is sequentially formed on the upper surface of the light emitting device panel 100 in the above-described order, thereby lowering the reflectance and color value from the side surface, thereby obtaining a thinning effect of the polarizing plate. When the polarizing film 220 and the patterned retardation layer 210 are sequentially formed from the upper surface of the light emitting device panel 100, the effect of lowering the reflectance and color value at the side surface is remarkably weak.

The polarizing plate 200 is formed on the upper surface of the light emitting device panel 100 to reduce the reflectance and color value from the side when external light reaches the light emitting device panel 100, thereby improving the screen quality of the light emitting device display device. I can.

The polarizing plate 200 includes a pattern retardation layer 210 and a polarizing film 220 formed on an upper surface of the pattern retardation layer 210.

The pattern retardation layer 210 reduces reflectance and color values from the side surfaces by circularly polarizing and reflecting external light incident from the polarizing film 200. As shown in FIG. 1, the pattern retardation layer 210 is a single layer, and through this, the thickness of the polarizing plate can be reduced. The "single layer" refers to a layer formed by one coating when the pattern retardation layer includes a coating layer or a layer formed as a single film when the pattern retardation layer is a film.

The pattern phase difference layer 210 may have a thickness of more than 0 μm and 10 μm or less, specifically 0.1 μm to 8 μm, and more specifically 0.1 μm to 5 μm. In the above range, the polarizing plate can be thinned.

The patterned phase difference layer 210 is a patterned phase difference layer. The "patterned retardation layer" is a layer in which two regions having different slow axis directions are alternately formed with each other. Two regions having different slow axis directions are referred to as a first phase difference region and a second phase difference region. The first phase difference region and the second phase difference region have different slow axis directions. Since the polarizing plate 200 includes the patterned retardation layer 210, even in a single-layered retardation layer, reflectance and color values from the side surfaces may be reduced, and the thickness of the retardation layer 210 and the polarizing plate may be significantly reduced. In particular, even if the polarizing plate 200 does not include the positive C plate, the pattern retardation layer 210 may reduce a change in color value at the side.

In one embodiment, the retardation layer 210 includes only a first phase difference region and a second phase difference region having different slow axis directions and alternately formed with each other.

2, in the pattern phase difference layer 210, a first phase difference region 211 having a first ground axis 211a and a second phase difference region 212 having a second ground axis 212a alternately Is formed by The first ground axis 211a and the second ground axis 212a cross each other. Since the first ground axis 211a and the second ground axis 212a are formed to cross each other, the pattern phase difference layer 210 has the effect of each of the first phase difference region 211 and the second phase difference region 212 even by a single layer. Can be implemented.

The angle formed by the first ground axis 211a of the first phase difference region 211 and the second ground axis 212a of the second phase difference region 212 is 80° to 100°, specifically 85° to 95°, more Specifically, it may be 90°. In the above range, the front reflectance and side color may have excellent effects.

The relationship between the axes of the first ground axis 211a of the first phase difference region 211 and the second ground axis 212a of the second phase difference region 212 and the absorption axis of the polarizing film should be considered. This can significantly lower the color value and reflectance from the side.

Specifically, in the first embodiment, when the absorption axis of the polarizing film is 0°, the angle formed by the first ground axis 211a of the first phase difference region is +35° to +55°, specifically +40° to + 50°, more specifically +45°, the angle formed by the second ground axis 212a of the second phase difference region is -35° to -55°, specifically -40° to -50°, more specifically -45° Can be. This can significantly lower the color value and reflectance from the side.

Specifically, in the second embodiment, when the absorption axis of the polarizing film is 0°, the angle formed by the first ground axis 211a of the first phase difference region is -35° to -55°, specifically -40° to- 50°, more specifically -45°, the angle formed by the second ground axis 212a of the second phase difference region is +35° to +55°, specifically +40° to +50°, more specifically +45° Can be. This can significantly lower the color value and reflectance from the side.

In the expression of the angle, "+" and "-" mean angles in a clockwise direction and a counterclockwise direction based on the absorption axis 0° of the polarizing film, respectively.

Preferably, the light emitting device display device may be the first embodiment.

The first phase difference region 211 and the second phase difference region 212 may have the same or different in-plane phase difference. Specifically, at a wavelength of 550 nm between the first phase difference region 211 and the second phase difference region 212, the absolute value of the difference of the in-plane phase difference may be 0 nm to 30 nm, specifically 0 nm to 10 nm, and more specifically 0 nm to 5 nm. In the above range, the reflectance is low and the side color may be excellent.

The first phase difference region 211 may have an in-plane retardation Re at a wavelength of 550 nm of 110 nm to 170 nm, specifically 130 nm to 150 nm, and more specifically 140 nm to 148 nm. In the above range, the reflectance is low and the color may be excellent.

The second phase difference region 212 may have an in-plane retardation Re of 110 nm to 170 nm, specifically 130 nm to 150 nm, and more specifically 140 nm to 148 nm at a wavelength of 550 nm. In the above range, the reflectance is low and the color may be excellent.

The pattern retardation layer 210 may have an in-plane retardation Re at a wavelength of 550 nm of 110 nm to 170 nm, specifically 130 nm to 150 nm, and more specifically 140 nm to 148 nm. In the above range, it is possible to improve reflectance and color values from the side.

The pattern retardation layer 210 may have a retardation Rth in the thickness direction at a wavelength of 550nm of -150nm to 150nm, specifically -120nm to 120nm, more specifically -90nm to 90nm, and most specifically 0nm to 90nm. In the above range, it is possible to improve reflectance and color values from the side.

The pattern retardation layer 210 may have a biaxial degree NZ of -2 to 2, specifically -1.5 to 1.5, more specifically -1.2 to 1.2, and most specifically 0 to 1.2 at a wavelength of 550 nm. In the above range, it is possible to improve reflectance and color values from the side.

The pattern retardation layer may be implemented by adjusting the in-plane retardation and the retardation in the thickness direction described above by adjusting the coating thickness of the liquid crystal composition described below. The pattern retardation layer may be implemented by adjusting the type of liquid crystal and the liquid crystal content in the liquid crystal composition described below in the degree of biaxiality.

In one embodiment, the patterned retardation layer 210 has reverse wavelength dispersion.

The pattern phase difference layer 210 may have reverse wavelength dispersion, thereby further improving reflectance and color values from the side. The pattern phase difference layer 210 may be 0<Re(450)/Re(550)<1, and Re(650)/Re(550)>1. For example, the pattern phase difference layer 210 has a Re(450)/Re(550) of 0.7 or more and less than 1, specifically 0.75 to 0.95, and a Re(650)/Re(550) of more than 1 and 1.5 or less, specifically 1.01 To 1.3. In the above range, the reflectance and color value at the side can be further improved. The "Re(450)", "Re(550)", and "Re(650)" mean in-plane retardation at wavelengths of 450nm, 550nm, and 650nm of the retardation layer, respectively.

In one embodiment, Re (450) may be 90nm to 140nm, specifically 110nm to 135nm, Re (650) may be 140nm to 190nm, specifically 140nm to 165nm. In the above range, there may be an effect of having a low front reflectance.

The above-described reverse wavelength dispersion may be adjusted by the composition of raw materials and process conditions when forming the patterned retardation layer.

The pattern retardation layer 210 may be a film formed of an optically transparent resin. However, in order to simplify the manufacturing process of the pattern retardation layer 210 and to reduce the thickness, the pattern retardation layer 210 may be a liquid crystal coating layer or a liquid crystal film.

The liquid crystal coating layer or the liquid crystal film may further include an alignment layer in the pattern phase difference layer 210 to implement the above-described phase difference.

Referring to FIG. 3, a method of manufacturing the patterned phase difference layer 210 will be described.

Through this, a first ground axis to form the first phase difference region may be formed. At this time, the formation of the first ground axis may be facilitated by disposing the mask pattern 5 having a predetermined interval between the photo-alignment layer and the WGP. The spacing of the mask pattern may be more than 0㎛ 1000㎛ or less, preferably 10㎛ to 800㎛, more preferably 20㎛ to 500㎛. Within the above range, it is possible to prevent the patterns of the first phase difference region and the second phase difference region from being visually recognized by the light emitting device display.
