Polarizer and organic light emitting display device comprising the same {POLARIZER AND ORGANIC LIGHT EMITTING DISPLAY DEVICE COMPRISING THE SAME}

The present invention relates to a polarizer and an organic light emitting display device having the same, and more specifically, to a polarizer that can reduce damage to the polarizer and the organic light emitting display panel while simplifying the manufacturing process by improving the structure of the polarizer, and to an organic light emitting display device having the same. It relates to a light emitting display device.

Recently, as we entered the full-fledged information age, the display field, which visually expresses electrical information signals, has developed rapidly, and in response to this, various display devices with excellent performance such as thinner, lighter, and lower power consumption have been developed. Device) is being developed.

Display devices include Liquid Crystal Display device (LCD), Organic Light Emitting Display (OLED), Electrophoretic Display (EPD, Electric Paper Display), and Plasma Display Panel. device: PDP), field emission display device (FED), electro luminescence display device (ELD), and electro-wetting display (EWD).

One of these display devices, an organic light emitting display device, is a self-luminous device and does not require a separate light source used in a liquid crystal display device, which is a non-light emitting device, so it can be lightweight and thin. In addition, it has superior viewing angle and contrast ratio compared to liquid crystal display devices, is advantageous in terms of power consumption, can be driven at low direct current voltage, has a fast response speed, is strong against external shocks because the internal components are solid, and has a wide operating temperature range. It has advantages.

Meanwhile, the organic light emitting display device is included on the organic light emitting display panel so that the organic light emitting display panel does not directly contact the outside. At this time, as organic light emitting display devices become lighter and thinner, and to provide a wider display area to users, technology is being used to minimize the bezel. Additionally, in order to add design elements while minimizing the bezel, a technology is being used to form the corners of the cover glass into a round shape and to form the outer edge of the cover glass into a curved surface. However, depending on the shape of the cover glass, the gap between the cover glass and the polarizer disposed on the organic light emitting display panel is not secured, and a portion of the polarizer may crack, resulting in a defective organic light emitting display device.

The inventors of the present invention recognized that a sufficient gap must be secured between the cover glass, the organic light emitting display panel, and the polarizer, depending on the shape of the cover glass as described above. If the gap is not secured, the organic light emitting display panel and the polarizer, especially the adhesive layer disposed on the polarization layer of the polarizer, vibrate and interfere with the cover glass due to an impact applied to the organic light emitting display device. At this time, the plurality of edges of the adhesive layer mainly interfere with the cover glass, causing cracks, which may lead to defects in the organic light emitting display device. Accordingly, the inventors of the present invention recognized that a sufficient gap must be secured between the plurality of edges of the adhesive layer of the cover glass and the polarizing plate.

Accordingly, the inventors of the present invention recognized that the gap between the adhesive layer and the cover glass can be secured by manufacturing the adhesive layer disposed on the polarizing layer of the polarizing plate to a size smaller than the polarizing layer and attaching the adhesive layer and the polarizing layer separately. However, the inventors of the present invention found that as the process of separately attaching the adhesive layer and polarizing layer was added to the above-described process, new equipment was needed, and new defects occurred during the attachment process of the adhesive layer, which could eventually reduce the overall yield. was recognized.

In addition, the adhesive layer can fix the polarizing layer to the cover glass or other components located on the polarizer and reduce vibration of the polarizing layer, and some areas of the polarizing layer where the first adhesive layer is not disposed are used in the organic light emitting display device. It may vibrate due to movement or impact. As the polarizing layer vibrates, it interferes with the cover glass, and the possibility of defects in the polarizing layer or the organic light emitting display panel may also increase. Accordingly, the inventors of the present invention have invented a polarizing plate with a new structure in which the adhesive layer can secure the polarizing layer as much as possible while securing the gap with the cover glass, and no additional process is required for manufacturing the polarizing plate, and an organic light emitting display device including the same. .

Accordingly, the problem to be solved by the present invention is to provide a polarizing plate that can secure the gap between the adhesive layer of the polarizing plate and the cover glass while simplifying the process, and an organic light emitting display device including the same.

Another problem to be solved by the present invention is to provide a polarizing plate that can reduce vibration of the polarizing layer while securing a gap between the adhesive layer and the cover glass, and an organic light emitting display device including the same.

Another problem to be solved by the present invention is to provide a polarizing plate that can prevent phenomena such as bending that may occur in the process of bonding the polarizing plate to an organic light emitting display panel and an organic light emitting display device including the same.

Hereinafter, the present invention will be described with reference to the drawings.

1 is a plan view of a circular polarizer according to an embodiment of the present invention. FIG. 2 is a cross-sectional view taken along line II-II' of FIG. 1. Referring to Figures 1 and 2, the primary polarizer 10 according to an embodiment of the present invention includes a first primary protective film 11, a first primary adhesive layer 12, a primary polarizing layer 13, and a second primary protective film. It includes an adhesive layer 14 and a second primary protective film 15. In FIG. 1 , for convenience of explanation, only the first primary adhesive layer 12 and the primary polarizing layer 13 among the components of the primary polarizer 10 are shown.

Referring to FIG. 1, the primary polarizer 10 is composed of a plurality of cells (CE). The led polarizer 10 according to an embodiment of the present invention is used to manufacture a polarizer in units of a plurality of cells (CE), and is a polarizer for forming a plurality of polarizers in units of ledgers. That is, after manufacturing the raw polarizing plate 10 as shown in FIG. 1, the polarizing plate as shown in FIGS. 3 and 4 can be manufactured by cutting it into individual cells (CE).

The primary polarization layer 13 is a layer for polarizing light incident on the primary polarization layer 13. The primary polarizing layer 13 may be composed of a plurality of layers to selectively transmit light, that is, to polarize light. For example, the primary polarizing layer 13 may have a multi-layer structure including PVA (Poly Vinyl Alcohol), which has polarization properties through a stretching process, and TAC (Triacetate Cellulose) disposed on both sides of the PVA, but is limited to this. It can be formed into various layers and structures that can polarize light without being polarized.

The primary polarizing layer 13 of the primary polarizing plate 10 may be a circularly polarizing layer that produces circularly polarized light. The organic light emitting display panel of the organic light emitting display device is applied to thin film transistors, organic light emitting devices, wiring, etc. and includes various metal materials with high reflectivity. Accordingly, external light incident from the outside of the organic light emitting display panel may be reflected from the metal material, and the visibility of the organic light emitting display device may be reduced due to the reflection of the external light. However, when a polarizing layer is attached to an organic light emitting display device, the polarizing layer prevents reflection of external light through circular polarization, thereby increasing the outdoor visibility of the organic light emitting display device.

Referring to FIG. 1, the first primary adhesive layer 12 is disposed on the upper surface of the primary polarizing layer 13 and is used to adhere the primary polarizing layer 13 to other components. The first primary adhesive layer 12 may be made of an adhesive material, for example, OCA (Optical Clear Adhesive). Since the first primary adhesive layer 12 must transmit light incident on the primary polarizing layer 13, excellent transmittance and adhesion are required. Accordingly, the first primary adhesive layer 12 may be made of an adhesive material with excellent permeability such as OCA, but is not limited thereto. When the first mother adhesive layer 12 is made of OCA, the thickness of the first mother adhesive layer 12 may be about 100 to 150 μm.

The first mother adhesive layer 12 includes a plurality of first holes (H1) and a plurality of second holes (H2). As will be described later in relation to the polarizer and the organic light emitting display device, the plurality of first holes H1 and the plurality of second holes H2 are formed by cutting a plurality of corners of the first adhesive layer and forming a plurality of corners of the first adhesive layer and the cover glass. This is to ensure a certain distance between them. Additionally, by ensuring a certain gap between the plurality of edges of the first adhesive layer and the cover glass, damage to the organic light emitting display device due to interference between the first adhesive layer and the cover glass can be prevented. This will be described in detail later with reference to FIGS. 11 to 14.

Referring to FIG. 1, the plurality of first holes H1 expose the edges of the plurality of cells CE, the vertices of which are in contact with each other. For example, as shown in FIG. 1, when the number of cells (CE) contacting each other at one vertex is four, each of the plurality of first holes (H1) exposes the corners of the four cells (CE). It can be formed as follows. That is, the plurality of first holes H1 are formed at both edges of one of the plurality of sides of the plurality of cells CE.

Each of the plurality of first holes H1 may have a polygonal shape with straight sides. For example, as shown in FIG. 1, when the plurality of first holes H1 expose the corners of the four cells CE, each of the plurality of first holes H1 is a square with straight sides. It may be a shape. However, the shape of the plurality of first holes is not limited to this, and one side may be composed of a plurality of straight lines. Accordingly, when the mother polarizer 10 is cut along the cutting line passing through the plurality of first holes H1, the plurality of edges of the first adhesive layer where the first mother adhesive layer 12 is cut are diagonal to each side of the polarization layer. is formed, and a plurality of edges of the polarizing layer may be exposed. The polarizing plate formed by cutting the original polarizing plate 10 will be described in detail later with reference to FIGS. 3 and 4.

The plurality of second holes H2 exposes all boundaries of two adjacent rows of the plurality of cells CE. For example, referring to FIG. 1 , the plurality of second holes H2 exposes all boundaries between cells CE in the first row and cells CE in the second row that are adjacent to each other. Accordingly, the first mother adhesive layer 12 may be spaced apart by a distance d from the boundary of two adjacent rows at the location where the plurality of second holes H2 are disposed. As the plurality of second holes H2 exposes all boundaries of two adjacent rows of the plurality of cells CE, the plurality of second holes H2 in the organic light emitting display device to which the polarizer is later attached is exposed. 1 A module process may be carried out to attach COF (Chip On Film), etc. to the exposed portion of the adhesive layer. This will be described in detail later with reference to FIGS. 11 to 14.

The plurality of second holes H2 extend in the row direction from the first part P1 and the first part P1 exposing the boundary of two adjacent columns, and two of the plurality of cells CE adjacent to each other. It includes a plurality of second parts P2 that expose part of the row border. In Figure 1, the row direction is defined as the horizontal direction and the column direction is defined as the vertical direction, but the present invention is not limited thereto. Accordingly, when the mother polarizer 10 is cut along the cutting line passing through the plurality of second holes H2, one side and a portion of the first mother adhesive layer 12 do not overlap the cut first adhesive layer. is exposed, and a plurality of edges of the first adhesive layer may also be formed diagonally on each side of the first adhesive layer.

The first portion P1 of the plurality of second holes H2 is a portion for performing a module process of the organic light emitting display device, as described above. The second portion (P2) of the plurality of second holes (H2) is a portion for exposing a plurality of edges of the polarizing layer. For example, the first part P1 of the plurality of second holes H2 exposes the boundary of two adjacent rows, and the second part P2 of the plurality of second holes H2 exposes the border of two adjacent rows. Partially exposes the border of two rows. That is, the first portion P1 of the plurality of second holes H2 may expose one side of the polarization layer so that one side of the polarization layer is disposed outside the corresponding side of the first adhesive layer. Also, like the plurality of first holes H1, the second portion P2 of the plurality of second holes H2 may have a plurality of edges of the first adhesive layer having a diagonal shape.

Referring to FIG. 1, a plurality of first holes H1 are formed at points where vertices of a plurality of cells CE contact each other, and a plurality of second holes H2 are formed at adjacent two of the plurality of cells CE. The boundaries of all rows are exposed. Accordingly, the number of first holes H1 may be greater than the number of second holes H2.

The plurality of first holes H1 and the plurality of second holes H2 are alternately arranged in the column direction. For example, as shown in FIG. 1, when the second hole H2 is placed between the cells CE placed in the first row and the cells CE placed in the second row, it is placed in the second row. The first hole H1 may be placed between the cells CE placed in the third row and the cells CE placed in the third row, and this arrangement may be made repeatedly.

The primary polarizing layer 13 includes a dummy portion 12D surrounding both sides of the plurality of cells CE. The dummy portion 12D may connect portions of the first ledger adhesive layer 12 disposed in each row of the plurality of cells CE so that the polarizing plate can be formed as a ledger unit. The dummy portion 12D may be cut and removed during the polarizer manufacturing process.

Referring to FIG. 2, the second primary adhesive layer 14 is disposed on the lower surface of the primary polarizing layer 13 and is used to adhere the primary polarizing layer 13 to other components. The second primary adhesive layer 14 may be made of an adhesive material, for example, PSA (Pressure Sensitive Adhesive), that is, a pressure sensitive adhesive, but is not limited thereto. And, if the second primary adhesive layer 14 is made of PSA, the thickness of the second primary adhesive layer 14 may be about 5 to 15 μm.

In order to protect the primary polarizing layer 13 to which the first primary adhesive layer 12 and the second primary adhesive layer 14 are attached, a first primary protective film 11 is disposed on the upper surface of the first primary adhesive layer 12, and 2 A second primary protective film 15 is disposed on the lower surface of the primary adhesive layer 14. The led polarizer 10 manufactured in unit units may be moved from the position where the led polarizer 10 was manufactured to a position where the led polarizer 10 is attached to another component, for example, an organic light emitting display panel. In this way, in the process of moving the primary polarizer 10, the first primary adhesive layer 12, the second primary adhesive layer 14, and the primary polarizing layer 13 may be damaged by external impact, and the first primary adhesive layer 12 ) and foreign substances may adhere to the second motherboard adhesive layer 14. Accordingly, the led polarizer 10 according to an embodiment of the present invention has a first led adhesive layer 12 to protect the led polarizer layer 13 to which the first led adhesive layer 12 and the second led adhesive layer 14 are attached. ) It may include a first primary protective film 11 disposed on the upper surface and a second primary protective film 15 disposed on the lower surface of the second primary adhesive layer 14. The first primary protective film 11 and the second primary protective film 15 are later used as polarizers cut into cells (CE) for other components such as an organic light emitting display panel, cover glass, etc. of an organic light emitting display device. When attached, it can be removed.

As described above, since the first mother adhesive layer 12 includes a plurality of first holes H1 and a plurality of second holes H2, the first mother protective film 11 is in contact with the mother polarizing layer 13. You can. Specifically, a partial region of the mother polarizing layer 13 exposed through the plurality of first holes H1 and the plurality of second holes H2 formed in the first mother adhesive layer 12 is exposed to the first mother protective film 11. ) can be accessed. At this time, the first mother protective film 11 contacts only a portion of the area of the mother polarizing layer 13 exposed due to the plurality of first holes H1 and the plurality of second holes H2, as shown in FIG. 2. Alternatively, the entire area of the primary polarizing layer 13 exposed due to the plurality of first holes H1 and the plurality of second holes H2 may be contacted. The second primary protective film 15 may be arranged to be in contact with the entire lower surface of the second primary adhesive layer 14 .

Meanwhile, the first primary protective film 11 and the second primary protective film 15 may be formed of a general polymer material, for example, polyethylene terephthalate film, polytetrafluoroethylene film, , polyethylene film, polybutene film, polybutadiene film, vinyl chloride copolymer film, ethylene-vinyl acetate film, ethylene-propylene copolymer film , ethylene-acrylic acid ethyl copolymer film, ethylene-acrylic acid methyl copolymer film, or polyimide film. And, when the first and second director protective films 11 and 15 are made of polyethylene terephthalate (polyethylene terephthalate) film, the first and second director protective films 11 and 15 are The thickness may be 20 to 40 μm.

Hereinafter, with reference to FIGS. 3 and 4 , one polarizer separated from the mother polarizer 10 into cells (CE) through a cutting process will be described.

Figure 3 is a plan view of a polarizer according to an embodiment of the present invention. FIG. 4 is a cross-sectional view taken along line IV-IV' of FIG. 3. 3 and 4, the polarizing plate 100 includes a first protective film 110, a first adhesive layer 120, a polarizing layer 130, a second adhesive layer 140, and a second protective film 150. Includes.

The polarizing layer 130 is a polarizing layer obtained by cutting the mother polarizing layer 13 in units of cells (CE) as shown in FIGS. 1 and 2 . Except that the polarization layer 130 is cut in units of cells (CE), the polarization layer 130 is substantially the same as the mother polarization layer 13, and thus redundant description will be omitted.

Referring to FIG. 3, the first adhesive layer 120 is disposed on the upper surface of the polarizing layer 130. The first adhesive layer 120 is used to adhere the polarizing layer 130 to the cover glass.

The plurality of edges 120C of the first adhesive layer 120 are diagonal to each side of the first adhesive layer 120. Accordingly, the plurality of edges 120C of the first adhesive layer 120 are disposed inside the plurality of edges 130C of the polarizing layer 130, so that the plurality of edges 120C of the first adhesive layer 120 are the polarizing layer 120C. It may be disposed closer to the center of the polarizing plate 100 than to the plurality of corners 130C of 130.

The shape of the plurality of corners 120C of the first adhesive layer 120 is similar to the plurality of first holes H1 and the plurality of second holes disposed in the first mother adhesive layer 12 described above with reference to FIGS. 1 and 2. It is determined by (H2). For example, the shape of the plurality of corners 120C of the first adhesive layer 120 may be such that two corners 120C are formed in a diagonal shape by the plurality of first holes H1. Additionally, the remaining two corners 120C may be formed in a diagonal shape by the first portion P1 of the plurality of second holes H2.

One side 130L of the plurality of sides of the polarization layer 130 is disposed outside the corresponding one side 120L of the plurality of sides of the first adhesive layer 120. That is, one side 120L of the plurality of sides of the first adhesive layer 120 is closer by a distance d to the center of the polarizing plate 100 than the corresponding side 130L of the plurality of sides of the polarization layer 130. It is placed. Accordingly, a partial area and side 130L of the polarizing layer 130 disposed on the lower surface of the first adhesive layer 120 may be exposed without overlapping with the first adhesive layer 120. At this time, the exposed side 130L of the polarization layer 130 may be formed by the second portion P2 of the plurality of second holes H2, as previously described with reference to FIGS. 1 and 2.

Except for one side (130L) among the plurality of sides of the polarizing layer 130, the remaining sides overlap with the corresponding side among the plurality of sides of the first adhesive layer 120. Accordingly, the first adhesive layer 120 has no area, side, or corner 120C extending outside of the polarizing layer 130, and the polarizing layer 130 has a larger area than the first adhesive layer 120. In the polarizing plate 100 according to an embodiment of the present invention, the remaining sides of the first adhesive layer 120 except for the removed portion overlap with the sides of the corresponding polarizing layer. That is, as shown in FIG. 3, three sides of the first adhesive layer 120 overlap with three sides of the polarizing layer 130, and the ends coincide with each other. Accordingly, since the first adhesive layer 120 remains on the three sides of the polarizer 100, the high rigidity of the polarizer 100 can be maintained.

In the polarizing plate according to an embodiment of the present invention, a plurality of edges 120C of the first adhesive layer 120 are formed in a diagonal shape to secure a certain gap between the first adhesive layer 120 and the cover glass, and the exposed A module process for attaching a COF or the like to a partial area of the polarization layer 130 may be performed. This will be described in detail later with reference to FIGS. 11 to 14.

Except for the above-described content, the first adhesive layer 130 is substantially the same as the first mother adhesive layer 13, and thus redundant description is omitted.

The second adhesive layer 140 is disposed on the lower surface of the polarizing layer 130 and is used to adhere the polarizing layer 130 to other components. The second adhesive layer 140 is a unit second adhesive layer 140 in which the second mother adhesive layer 14 as shown in FIG. 2 is cut into cells (CE). Except that the second adhesive layer 140 is cut in units of cells (CE), the second adhesive layer 140 is substantially the same as the second mother adhesive layer 14, and thus redundant description will be omitted.

Referring to FIG. 4, the first protective film 110 is disposed on the upper surface of the first adhesive layer 120, and the second protective film 150 is disposed on the lower surface of the second adhesive layer 140.

And, the first protective film 110 and the second protective film 150 can be removed later when the polarizer 100 is attached to another component.

The first protective film 110 may be in contact with the polarizing layer 130. Specifically, a plurality of edges of the first protective film 110 may contact a plurality of edges 130C of the polarizing layer 130 that do not overlap the first adhesive layer 120. At this time, as shown in FIG. 4, the first protective film 110 may contact only a portion of the exposed area of the polarizing layer 130 without overlapping the first adhesive layer 120, or may contact the entire area of the polarizing layer 130. You can come into contact with. Meanwhile, the second protective film 150 does not directly contact the polarizing layer 130 like the first protective film 110, but may contact the entire lower surface of the second adhesive layer 140.

A plurality of sides of the first protective film 110, the polarizing layer 130, and the second protective film 150 correspond to each other. That is, the first protective film 110, the polarizing layer 130, and the second protective film 150 have the same shape and the same area, and are arranged so that their centers coincide with each other. Therefore, the first protective film 110 and the second protective film 150 can completely cover the polarizing layer 130 and the first adhesive layer 120 and the second adhesive layer 140 attached to the polarizing layer 130. , the polarizing layer 130, the first adhesive layer 120, and the second adhesive layer 140 can be protected from external foreign substances or impacts.

A cutting process is required to form a plurality of edges 120C of the first adhesive layer 120 disposed on the upper surface of the polarizing layer 130 diagonally on each side. Accordingly, in a state where the first mother adhesive layer 12 and the mother polarizing layer 13 are first attached, a plurality of first holes H1 and a plurality of second holes H2 are formed in the first mother adhesive layer 12. After performing the cutting process, the polarizing plate 100 can be manufactured where the plurality of edges 120C of the first adhesive layer 120 are diagonal on each side. However, after the first adhesive layer 120 and the polarizing layer 130 are attached, when a plurality of first holes H1 and a plurality of second holes H2 are formed in the first adhesive layer 120, the first hole H1 and the second hole H2 are formed in the first adhesive layer 120. The polarizing layer 130 disposed on the lower surface of the adhesive layer 120 may also be damaged by being cut or scratched.

Accordingly, the led polarizer 10 according to an embodiment of the present invention first forms a plurality of first holes (H1) and a plurality of second holes (H2) in the first ledger adhesive layer 12, and then forms a plurality of first holes (H1) and a plurality of second holes (H2) in the first ledger adhesive layer 12. Since the adhesive layer 12 and the primary polarizing layer 13 can be attached, damage to the polarizing layer 130 of the polarizing plate 100 can be prevented. That is, the raw polarizer 10 and the polarizer 100 according to an embodiment of the present invention are processed so that the edges 120C of the first adhesive layer 120 disposed on the polarization layer 130 are diagonal on each side. Damage to the polarization layer 130 can be prevented during the process. In addition, since a plurality of polarizers 100 can be manufactured using the composite polarizer 10 in each module, the process can also be simplified.

In addition, in the led polarizer 10 according to an embodiment of the present invention, the first led adhesive layer 12 includes a plurality of first holes H1 and a plurality of second holes H2, and the plurality of first holes H1 The first protective film 11 may be in contact with the primary polarizing layer 13 in (H1) and the plurality of second holes (H2). Specifically, a partial region of the mother polarizing layer 13 exposed through the plurality of first holes H1 and the plurality of second holes H2 formed in the first mother adhesive layer 12 is exposed to the first mother protective film 11. ) can be accessed. Accordingly, in the polarizing plate 100 according to an embodiment of the present invention, the plurality of edges of the first protective film 110 are the plurality of edges 130C of the polarizing layer 130 that do not overlap the first adhesive layer 120. You can access it. Accordingly, in the process of bonding the polarizer 100 to a display panel such as an organic light emitting display panel, for example, a roll-to-roll process, the polarizer layer 130 and the first protective film 110 are separated. As a result, phenomena such as bending that may occur can be minimized. Therefore, in the bonding process of the polarizer 100 and the display panel according to an embodiment of the present invention, the polarizer 100 can be uniformly attached to the entire area of the display panel.

Figure 5 is a plan view of a circular polarizer according to another embodiment of the present invention. Figure 6 is a plan view of a polarizing plate according to another embodiment of the present invention. Referring to FIGS. 5 and 6, the led polarizer 20 and the polarizer 200 according to another embodiment of the present invention are the first led polarizer 10 and the polarizer 100 of FIGS. 1 to 4. Since the shapes of the plurality of first holes H1 and the plurality of second holes H2 of the adhesive layer 22 are different, and thus the shape of the first adhesive layer 220 is different, they are substantially the same, so there is overlap. The explanation is omitted.

Referring to FIG. 5, the first adhesive layer 22 of the original polarizer 20 according to another embodiment of the present invention includes a plurality of first holes H1 and a plurality of second holes H2. The plurality of first holes H1 expose the edges of the plurality of cells CE, the vertices of which are in contact with each other. And, each of the plurality of first holes H1 has a polygonal shape with a transition curve. Accordingly, when the primary polarizer 20 is cut along the cutting line passing through the plurality of first holes H1, as shown in FIG. 6, the plurality of corners 220C of the first adhesive layer 220 have a round shape. have

Each of the plurality of first holes H1 may have a polygonal shape with a transition curve. For example, as shown in FIG. 5, when the plurality of first holes H1 expose the corners of the four cells CE, each of the plurality of first holes H1 has a convex curve toward the center. It may have a square shape with sides. However, the shape of the plurality of first holes H1 may be a square shape with sides that are concave and curved toward the center, but is not limited thereto. Accordingly, when the primary polarizer 20 is cut along the cutting line passing through the plurality of first holes H1, the plurality of edges 220C of the first adhesive layer 220 where the first primary adhesive layer 22 is cut are polarized. The layer 130 is formed in a round shape on each side, and a plurality of edges 130C of the polarization layer 130 may be exposed.

The plurality of second holes H2 includes the first part P1 and the second part P2, and exposes all boundaries of two adjacent rows of the plurality of cells CE. The first part (P1) of the plurality of second holes (H2) exposes the boundary of two adjacent rows, and the second part (P2) of the plurality of second holes (H2) exposes the border of two adjacent rows. Some boundaries are exposed. Since the first portion P1 of the plurality of second holes H2 is the same as previously described with reference to FIGS. 1 and 2, duplicate description will be omitted.

Meanwhile, like the plurality of first holes H1, some of the edges 220C of the plurality of edges 220C of the first adhesive layer 220 of the second portion P2 of the plurality of second holes H2 are rounded. You can have it. Accordingly, when the primary polarizer 20 is cut along the cutting line passing through the plurality of second holes H2, as shown in FIG. 6, the plurality of corners 220C of the first adhesive layer 220 have a round shape. While doing so, the side 130L and a partial area of the polarization layer 130 are exposed.

The primary polarizer 20 according to another embodiment of the present invention first forms a plurality of first holes (H1) and a plurality of second holes (H2) in the first primary adhesive layer 22, and then forms the first primary adhesive layer ( 22) and the primary polarizing layer 13 can be attached. Accordingly, while preventing damage to the polarizing layer 130, the plurality of corners 220C of the first adhesive layer 220 can be made to have a round shape. In addition, after attaching the first mother adhesive layer 22 and the mother polarizing layer 13 composed of a plurality of rows, one polarizing plate 200 can be manufactured through a cutting process, thereby simplifying the process.

Therefore, the primary polarizer 20 and the polarizer 200 according to an embodiment of the present invention are processed so that the edges 220C of the first adhesive layer 220 disposed on the polarization layer 130 are diagonal on each side. Damage to the polarizing layer 130 can be prevented during the process. In addition, rather than attaching the first adhesive layer 220 and the polarizing layer 130 individually, the first mother adhesive layer 22 and the mother polarizing layer 13, which are composed of a plurality of cells (CE), are attached through a single attachment process. Since it can be attached, the attachment process can also be simplified.

In addition, in the mother polarizer 10 according to an embodiment of the present invention, the mother polarizing layer exposed through the plurality of first holes H1 and the plurality of second holes H2 formed in the first mother adhesive layer 12 ( Some areas of 13) may be in contact with the first protective film 11. Accordingly, in the polarizing plate 100 according to an embodiment of the present invention, the plurality of edges of the first protective film 110 are the plurality of edges 130C of the polarizing layer 130 that do not overlap the first adhesive layer 120. You can access it. Accordingly, in the process of bonding the polarizer 100, such as the roll-to-roll process, to a display panel, such as an organic light emitting display panel, phenomena such as bending that may occur as the polarizing layer 130 and the first protective film 110 are spaced apart. is minimized, and the polarizer 100 can be uniformly attached to the entire area of the display panel.

Figure 7 is a plan view of a circular polarizer according to another embodiment of the present invention. Figure 8 is a cross-sectional view taken along line VIII-VIII' of Figure 7. Referring to Figures 7 and 8, the primary polarizer 30 according to another embodiment of the present invention has a shape of the first primary protective film 31 compared to the primary polarizer 10 shown in Figures 1 and 2. Since these are different and are substantially the same except that the step compensation unit 36 and the auxiliary adhesive layer 37 are added, duplicate descriptions will be omitted. In FIG. 7 , for convenience of explanation, only the first primary adhesive layer 12, the primary polarizing layer 13, and the step compensation unit 36 among the components of the primary polarizer 30 are shown.

Referring to FIGS. 7 and 8 , a plurality of step compensation units 36 are disposed in a plurality of first holes H1 and a plurality of second holes H2 of the first mother adhesive layer 12 . The plurality of step compensators 36 correct the step between the first mother protective film 31 and the mother polarizing layer 13 at positions corresponding to the plurality of first holes H1 and the plurality of second holes H2. It is structured to compensate. That is, the plurality of step compensation units 36 may fill the space between the first protective film 31 and the primary polarizing layer 13 together with a plurality of auxiliary adhesive layers 37.

Referring to FIGS. 7 and 8 , the plurality of step compensation units 36 are disposed on the same plane as the first mother adhesive layer 12 in the plurality of first holes H1 and the plurality of second holes H2. . Additionally, the plurality of step compensation units 36 are arranged to be spaced apart from the first mother adhesive layer 12. As will be explained later, the plurality of step compensators 36 are removed from the final product and must not be in contact with the first mother adhesive layer 12. Therefore, the plurality of step compensation parts 36 are connected to the first mother adhesive layer 12. It is placed spaced apart from the.

As the plurality of step compensation units 36 are disposed in the plurality of first holes H1 and the plurality of second holes H2, the first original protective film 31 is formed in a flat shape. That is, as shown in FIG. 8, the first primary protective film 31 does not include separate protrusions and may be formed in the form of a flat film.

Referring to FIG. 8 , a plurality of auxiliary adhesive layers 37 are disposed between the plurality of step compensation units 36 and the first protective film 31. The plurality of auxiliary adhesive layers 37 are adhesive layers for attaching the plurality of step compensation parts 36 to the first motherboard protective film 31 . The plurality of auxiliary adhesive layers 37 may have the same shape as the plurality of step compensation parts 36 on a plane. The plurality of auxiliary adhesive layers 37 may have a minimum thickness for attaching the plurality of step compensators 36 to the first protective film 31 .

The plurality of auxiliary adhesive layers 37 may be made of the same material as the first primary adhesive layer 12. For example, the plurality of auxiliary adhesive layers 37 may be made of OCA. However, since the plurality of auxiliary adhesive layers 37 are removed in a later display device and do not necessarily need to be transparent, the plurality of auxiliary adhesive layers 37 may be made of a different material from the first master adhesive layer 12.

As the plurality of auxiliary adhesive layers 37 are made of the same material as the first primary adhesive layer 12, the compressive modulus for vertical compression of the plurality of auxiliary adhesive layers 37 is the vertical compression modulus of the first primary adhesive layer 12. It may be the same as the modulus for compression. Here, the modulus for vertical compression refers to the modulus for when a specific object is pressed in the vertical direction, that is, when a specific object is compressed in the vertical direction, and the modulus for vertical tension (tensile modulus), which acts in parallel This modulus is defined differently from the shear modulus. For example, when the plurality of auxiliary adhesive layers 37 and the first mother adhesive layer 12 are made of OCA, the modulus for vertical compression of the plurality of auxiliary adhesive layers 37 and the first mother adhesive layer 12 is 0.140 MPa. You can.

The sum of the thicknesses of the plurality of step compensation parts 36 and the plurality of auxiliary adhesive layers 37 may be equal to the thickness of the first mother adhesive layer 12. When the plurality of step compensators 36 and the plurality of auxiliary adhesive layers 37 are not disposed in the plurality of first holes H1 and the plurality of second holes H2, the plurality of first holes H1 and the plurality of second holes H2 A space may be formed between the first protective film 31 and the polarizing layer 13 in the second hole H2. At this time, the separation space refers to an empty space that can be created by separating the first protective film 31 and the polarizing layer 13 in the plurality of first holes (H1) and the plurality of second holes (H2). . In this case, in the process of bonding the cell-level polarizer cut by cutting the mother polarizer 30 into cells to a display panel such as an organic light emitting display panel, phenomena such as bending may occur due to the above-mentioned separation space, and the polarizer may not display the display. It may not be evenly attached to the panel.

Accordingly, in the mother polarizer 10 according to another embodiment of the present invention, the sum of the thicknesses of the plurality of step compensators 36 and the plurality of auxiliary adhesive layers 37 is equal to the thickness of the first mother adhesive layer 12. Thus, the above-mentioned separation space can be minimized. However, since the plurality of auxiliary adhesive layers 37 have a minimum thickness for attaching the plurality of step compensation parts 36 and the first motherboard protective film 31, the thickness of the plurality of auxiliary adhesive layers 37 is ignored. , it may be defined that the plurality of step compensation units 36 and the first mother adhesive layer 12 have substantially the same thickness.

The modulus against vertical compression of the plurality of step compensators 36 may be similar to the modulus against vertical compression of the first ledger adhesive layer 12 . As described above, even when the sum of the thicknesses of the plurality of step compensation units 36 and the plurality of auxiliary adhesive layers 37 is the same as the thickness of the first mother adhesive layer 12, the plurality of step compensation units 36 and the plurality of auxiliary adhesive layers 37 If the deviation between the modulus against vertical compression of the auxiliary adhesive layer 37 and the modulus against vertical compression of the first ledger adhesive layer 12 is large, the polarizer is bonded to a display panel such as an organic light emitting display panel by a roll-to-roll process. Phenomenon such as bending may still occur during the process, and the polarizer may not be uniformly attached to the display panel. At this time, the roll-to-roll process is a process of bonding the polarizer and the display panel through a roller disposed on the polarizer and a roller disposed below the display panel, so that the plurality of step compensation parts 36 and the plurality of auxiliary adhesive layers 37 are vertically bonded. The modulus of compression should be similar to the modulus of vertical compression of the first primary adhesive layer 12. However, the plurality of auxiliary adhesive layers 37 may be made of the same material as the first mother adhesive layer 12, and the thickness of the plurality of auxiliary adhesive layers 37 may be so thin that they may be ignored, so in reality, a plurality of step compensation units The modulus for vertical compression of (36) may be similar to the modulus for vertical compression of the first ledger adhesive layer (12).

At this time, the modulus against vertical compression of the plurality of step compensation units 36 may be 1/10 to 10 times the modulus against vertical compression of the first ledger adhesive layer 12. For example, when the first mother adhesive layer 12 is made of OCA, the modulus against vertical compression of the plurality of step compensators 36 is 1/10 of the modulus against vertical compression of the first mother adhesive layer 12. It may be 0.014Mpa to 1.4Mpa, which is 10 times greater. If the modulus against vertical compression of the plurality of step compensators 36 is less than 1/10 times the modulus against vertical compression of the first ledger adhesive layer 12, that is, less than 0.014Mpa, the plurality of step compensators 36 Since the modulus for vertical compression of (36) is too small, it appears as if no material is attached to the plurality of first holes (H1) and the plurality of second holes (H2), so that the polarizer is formed into an organic light emitting display panel by a roll-to-roll process. During the bonding process to the display panel, phenomena such as bending may still occur, and the polarizer may not be uniformly attached to the display panel. In addition, when the modulus against vertical compression of the plurality of step compensators 36 is greater than 10 times the modulus against vertical compression of the first ledger adhesive layer 12, that is, greater than 1.4Mpa, the plurality of step compensators 36 The modulus for vertical compression in (36) may become too large, which may cause the display panel to become crumpled as if interference occurred due to the placement of foreign substances in the process of bonding the polarizer to a display panel such as an organic light emitting display panel by the roll-to-roll process. there is. For example, in the case of polyethylene terephthalate, which is mainly used as the first motherboard protective film 31, the modulus against vertical compression is about 4500Mpa, which is excessively larger than the modulus against vertical compression of the first motherboard adhesive layer 12. 1 If a plurality of step compensation units 36 are made of the same material as the primary protective film 31, the display panel may become wrinkled. Accordingly, the modulus against vertical compression of the plurality of step compensation units 36 may be 1/10 to 10 times the modulus against vertical compression of the first ledger adhesive layer 12, and the plurality of step compensation units 36 may be For example, it may be made of one of polyurethane, polyolefin, acrylic, and polypropylene.

Hereinafter, with reference to FIGS. 9 and 10 , one polarizer separated from the mother polarizer 30 into cells (CE) through a cutting process will be described.

Figure 9 is a plan view of a polarizer according to another embodiment of the present invention. FIG. 10 is a cross-sectional view taken along line XX' of FIG. 9. The polarizing plate 300 shown in FIGS. 9 and 10 has a different shape of the first protective film 310 compared to the polarizing plate 100 shown in FIGS. 3 and 4, and has a step compensation portion 360 and an auxiliary adhesive layer. Since it is substantially the same except for the addition of (370), redundant description will be omitted. In FIG. 9 , for convenience of explanation, only the first adhesive layer 120, the primary polarizing layer 130, and the step compensation unit 360 among the components of the polarizing plate 300 are shown.

9 and 10, the polarizing plate 300 includes a first protective film 310, a first adhesive layer 120, a polarizing layer 130, a second adhesive layer 140, a second protective film 150, It includes a plurality of step compensation units 360 and a plurality of auxiliary adhesive layers 370.

Referring to FIG. 9 , the plurality of edges 120C of the first adhesive layer 120 are diagonal to each side of the first adhesive layer 120 . Accordingly, the plurality of edges 120C of the first adhesive layer 120 are disposed inside the plurality of edges 130C of the polarizing layer 130, so that the plurality of edges 120C of the first adhesive layer 120 are the polarizing layer 120C. It may be disposed closer to the center of the polarizing plate 300 than to the plurality of corners 130C of 130. Additionally, one side 130L of the plurality of sides of the polarization layer 130 is disposed outside the corresponding one side 120L of the plurality of sides of the first adhesive layer 120.

Accordingly, a plurality of step compensation units 360 may be disposed on an area of the upper surface of the polarizing layer 130 that does not overlap the first adhesive layer 120. That is, as shown in FIGS. 9 and 10, the plurality of step compensation units 360 are connected to the first protective film 310 and the polarizing layer 130 to compensate for the step between the first protective film 310 and the polarizing layer 130. It may be placed in the space between the polarizing layers 130.

Referring to FIGS. 9 and 10 , the plurality of step compensation units 360 are disposed on the same plane as the first adhesive layer 120 . Additionally, the plurality of step compensation units 360 are arranged to be spaced apart from the first adhesive layer 120. That is, since the plurality of step compensation units 360 are removed from the final product, they should not be in contact with the first adhesive layer 120, and therefore, the plurality of step compensation units 360 are arranged to be spaced apart from the first adhesive layer 120. do.

The plurality of step compensation units 360 are disposed on the same plane as the first adhesive layer 120 on the polarizing layer 130, and are disposed farther from the center of the polarizing plate 300 than the plurality of corners of the first adhesive layer 130. . That is, since the plurality of step compensation units 360 are disposed in areas where the polarization layer 130 and the first adhesive layer 120 do not overlap, they are disposed in the outer area of the polarization layer 130, as shown in FIG. 9. , and may be disposed farther from the center of the polarizing plate 300 than the plurality of corners of the first adhesive layer 130.

Additionally, as the plurality of step compensation units 360 are disposed on the same plane as the first adhesive layer 120, the first protective film 310 is formed into a flat shape. That is, as shown in FIG. 10, the first protective film 310 does not include separate protrusions and may be formed in the form of a flat film.

Referring to FIG. 10 , a plurality of auxiliary adhesive layers 370 are disposed between the plurality of step compensation units 360 and the first protective film 310 . The plurality of auxiliary adhesive layers 370 are adhesive layers for attaching the plurality of step compensators 360 to the first protective film 310 . The plurality of auxiliary adhesive layers 370 may have the same shape as the plurality of step compensation units 360 on a plane. The plurality of auxiliary adhesive layers 370 may have a minimum thickness for attaching the plurality of step compensators 360 to the first protective film 310 .

The plurality of auxiliary adhesive layers 370 may be made of the same material as the first adhesive layer 120. For example, the plurality of auxiliary adhesive layers 370 may be made of OCA. However, since the plurality of auxiliary adhesive layers 370 are removed together with the first protective film 310 and do not necessarily need to be transparent, the plurality of auxiliary adhesive layers 370 may be made of a different material from the first adhesive layer 120. It may be possible.

As the plurality of auxiliary adhesive layers 370 are made of the same material as the first adhesive layer 120, the modulus against vertical compression of the plurality of auxiliary adhesive layers 370 is equal to the modulus against vertical compression of the first primary adhesive layer 120. may be the same. For example, when the plurality of auxiliary adhesive layers 370 and the first adhesive layer 120 are made of OCA, the modulus for vertical compression of the plurality of auxiliary adhesive layers 370 and the first adhesive layer 120 may be 0.140 MPa. .

The sum of the thicknesses of the plurality of step compensation units 360 and the plurality of auxiliary adhesive layers 370 may be equal to the thickness of the first adhesive layer 120. If the plurality of step compensators 360 and the plurality of auxiliary adhesive layers 370 are not arranged, a space may be generated between the first protective film 310 and the polarizing layer 130. In the process of bonding the polarizer 300 to a display panel, such as an organic light emitting display panel, phenomena such as bending may occur due to the above-mentioned space, and the polarizer 300 may not be uniformly attached to the display panel. Accordingly, in the polarizing plate 300 according to another embodiment of the present invention, the sum of the thicknesses of the plurality of step compensators 360 and the plurality of auxiliary adhesive layers 370 is equal to the thickness of the first adhesive layer 120, as described above. Separation space can be minimized. However, since the plurality of auxiliary adhesive layers 370 have a minimum thickness for attaching the plurality of step compensation units 360 and the first protective film 310, the thickness of the plurality of auxiliary adhesive layers 370 is ignored, It may be defined that the plurality of step compensation units 360 and the first adhesive layer 120 have substantially the same thickness.

The modulus of the plurality of step compensation units 360 against vertical compression may be similar to the modulus of the first adhesive layer 120 against vertical compression. As described above, even when the sum of the thicknesses of the plurality of step compensation units 360 and the plurality of auxiliary adhesive layers 370 is the same as the thickness of the first adhesive layer 120, the plurality of step compensation units 360 and the plurality of auxiliary adhesive layers 370 If the difference between the vertical compression modulus of the auxiliary adhesive layer 370 and the vertical compression modulus of the first adhesive layer 120 is large, the polarizer 300 is bonded to a display panel such as an organic light emitting display panel by a roll-to-roll process. During the process, phenomena such as bending may still occur, and the polarizer 300 may not be uniformly attached to the display panel. At this time, the roll-to-roll process is a process of bonding the polarizer 300 and the display panel through a roller disposed on the polarizer 300 and a roller disposed below the display panel, so a plurality of step compensation units 360 and a plurality of auxiliary The modulus of the vertical compression of the adhesive layer 370 should be similar to the modulus of the first adhesive layer 120. However, the plurality of auxiliary adhesive layers 370 may be made of the same material as the first adhesive layer 120, and the thickness of the plurality of auxiliary adhesive layers 370 may be very thin and may be ignored, so in reality, a plurality of step compensation units ( The modulus for vertical compression of 360 may be similar to the modulus for vertical compression of the first adhesive layer 120 .

At this time, the modulus against vertical compression of the plurality of step compensation units 360 may be 1/10 to 10 times the modulus against vertical compression of the first adhesive layer 120. For example, when the first adhesive layer 120 is made of OCA, the modulus against vertical compression of the plurality of step compensators 360 is 1/10 to 10 of the modulus against vertical compression of the first adhesive layer 120. It may be 0.014Mpa to 1.4Mpa. If the modulus for vertical compression of the plurality of step compensators 360 is less than 1/10 times the modulus for vertical compression of the first adhesive layer 120, that is, less than 0.014Mpa, the plurality of step compensators ( Since the modulus for vertical compression of 360) is too small, it is as if no material is actually attached, so phenomena such as bending still occur during the process of bonding the polarizer 300 to a display panel such as an organic light emitting display panel by a roll-to-roll process. This may occur, and the polarizer 300 may not be uniformly attached to the display panel. In addition, when the modulus for vertical compression of the plurality of step compensation units 360 is greater than 10 times the modulus for vertical compression of the first adhesive layer 120, that is, greater than 1.4Mpa, the plurality of step compensation units ( The modulus for vertical compression of 360) becomes too large, and the display panel may be crumpled as if foreign substances were placed and interfered with the process of bonding the polarizer 300 to a display panel such as an organic light emitting display panel by a roll-to-roll process. It can happen. For example, in the case of polyethylene terephthalate, which is mainly used as the first protective film 310, the modulus against vertical compression is about 4500Mpa, which is excessively larger than the modulus against vertical compression of the first adhesive layer 120. Therefore, when the plurality of step compensators 360 are made of the same material as the first protective film 310, the display panel may become wrinkled. Accordingly, the modulus against vertical compression of the plurality of step compensation units 360 may be 1/10 to 10 times the modulus against vertical compression of the first adhesive layer 120, and the plurality of step compensation units 360 may be, for example, For example, it may be made of one of polyurethane, polyolefine, acryl, and polypropylene.

In addition, in the led polarizer 30 according to another embodiment of the present invention, the first led adhesive layer 12 includes a plurality of first holes H1 and a plurality of second holes H2, and a plurality of first holes H1 and a plurality of second holes H2. A plurality of step compensators 36 and a plurality of auxiliary adhesive layers 37 will be disposed between the first mother protective film 11 and the mother polarizing layer 13 in the hole H1 and the plurality of second holes H2. You can. Accordingly, in the polarizing plate 300 according to another embodiment of the present invention, the sum of the thicknesses of the plurality of step compensation units 360 and the plurality of auxiliary adhesive layers 370 may be equal to the thickness of the first adhesive layer 120. . Accordingly, the plurality of step compensation units 360 and the plurality of auxiliary adhesive layers 370 may fill the space between the first protective film 310 and the polarizing layer 130. Accordingly, in the process of bonding the polarizer 300 to a display panel such as an organic light emitting display panel, for example, bending that may occur as the polarizer 130 and the first protective film 310 are spaced apart in a roll-to-roll process, etc. phenomenon can be minimized. Therefore, in the bonding process of the polarizer 300 and the display panel according to another embodiment of the present invention, the polarizer 300 can be uniformly attached to the entire area of the display panel.
