The present invention relates to an organic light emitting device, and more particularly, to a method of patterning a polymer organic film that is a light emitting layer of an organic light emitting device capable of expressing full color.

  In general, organic light emitting diodes inject electrons and holes into an emission layer from an electron injection electrode and a hole injection electrode, respectively, to inject the injected electrons. ) Is a device that emits light when an exciton combined with a hole falls from an excited state to a ground state.

Due to this principle, unlike the conventional thin film liquid crystal display device, since a separate light source is not required, there is an advantage in that the volume and weight of the device can be reduced.

The organic light emitting diode having the above operating characteristics may be classified into a passive matrix type and an active matrix type according to a driving method.

The passive matrix type organic light emitting device has a simple structure and a simple manufacturing method. However, the passive matrix type organic light emitting device has a high power consumption and a large area of the display device, and the opening ratio decreases as the number of wirings increases.

Therefore, passive matrix type organic light emitting diodes are used for small display devices, whereas active matrix type organic light emitting diodes are used for large area display devices.

As a method for realizing the color display of the aforementioned organic EL device, three methods are mainly proposed.

The first method is a method of forming a light emitting layer emitting red, green, and blue light by using different light emitting materials on each pixel displaying red, green, and blue colors. The light emitting layer realizes white light emission and divides it into three primary colors using a color filter.

Lastly, the third method is a method of expressing color by converting light from a blue light emitting layer into three primary colors in a color change medium.

A first method is generally used among the above three methods, and various methods of forming a polymer organic film pattern emitting different colors have been performed.

For example, a roll coating method, an ink-jet method, etc. can be mentioned, A roll coating method is demonstrated below with an example.

1 is a cross-sectional view schematically showing a roll-coating device.

As illustrated, the roll-coating method is a method of coating the organic film pattern 21 having a predetermined shape on the glass substrate 10 by using a plurality of rolls engaged with each other.

The roll-coating device for this is roughly composed of a doctor roll 11, an anilox roll 13, a printing roll 15 and a rubber plate 17.

Of the plurality of rolls, the doctor roll 11 is engaged with the anilox roll 13 to rotate, and the printing roll 15 is configured to engage with the anilox roll 13.

As shown in the side of the anilox roll 13, the fine groove 13a is formed.

In addition, a rubber plate (print mask) 17 having an arbitrary pattern is attached to one surface of the printing roll 15.

The pattern of the rubber plate 17 is an embossed pattern, and serves to directly coat a polymer organic film pattern emitting red, green, and blue light on the substrate 10 defined by a plurality of pixels.

Looking at the method of coating a color polymer organic film on a glass substrate using a roll-coating device having the configuration as described above are as follows.

First, the glass substrate 10 is fixed to an arbitrary fixing means 12.

Next, in the above-described configuration, the dispenser 19 is transferred to the anilox roll 13 to transfer the polymer organic material emitting any color.

As described above, when a printing apparatus composed of a plurality of rolls is operated, the doctor roll 11 rotates to engage with the anilox roll 13 to obtain a polymer organic material sprayed on the anilox roll 13. The polymer organic material deposited on the microgroove 13a of the anilox roll 13 is continuously deposited inside the anilox roll 13, and the anilox roll 13 and the printing roll 15 are formed. It is transferred again to the rubber plate 17 of the printing roll 15 as it rotates together.                         

Next, the polymer organic material transferred to the rubber plate 17 is coated with the polymer organic layer 21 on the substrate 10 in accordance with the embossed pattern of the rubber plate 17 as the printing roll 15 rotates.

By repeating the above-described process for each sub-pixel which intends to express red, green, and blue, a plurality of polymer organic film patterns emitting a predetermined color can be formed.

However, in the conventional roll-coating method or ink-jet method, it is difficult to uniformly adjust the thickness of the polymer film during polymer film formation, and it is also difficult to control the thickness of the polymer film as desired.

In addition, the contact between the substrate and the polymer is also poor, which is a fatal disadvantage in the reliability of the device.

The present invention has been proposed to solve the above problems, and after printing the polymer organic film on the front surface of the substrate by spin coating method, the unnecessary portion of the unnecessary part by the lift-up method using a stamp (stamp) The polymer organic film is removed to form a polymer organic film pattern that emits a specific color for each pixel.

Therefore, the method of forming the polymer organic film pattern according to the present invention as described above aims to improve the yield due to the reduction of material cost and process time.

The organic film pattern forming method for an organic light emitting device according to the present invention for achieving the above object is a step of defining a plurality of first, second, and third pixels representing red, green, blue on a transparent insulating substrate Wow; Forming a first polymer organic film emitting red light after oxygen plasma treatment of the entire surface of the substrate in which the pixel is defined; The convex portion of the stamp formed of the concave portion and the convex portion on the entire surface of the substrate on which the first polymer organic film is formed is contacted with the first polymer organic film formed on the second pixel and the third pixel, and then lifted up to remove it.

First Embodiment

The present invention is characterized by patterning a polymer organic film emitting red, green, and blue light, respectively, in a color organic electroluminescent device by a lift-up method using a stamp. It is done.

Below, 2A to 2E are cross-sectional views illustrating polymer organic film patterns according to a process sequence of the present invention.

First, as illustrated in FIG. 2A, a plurality of first, second, and third pixels Rp, Gp, and Bp for expressing green, blue, and red are defined on the transparent insulating substrate 100.

A diffusion barrier 102 is formed at the boundary of each of the pixels Rp, Gp, and Bp defined above.

The diffusion barrier 102 is made of a polymer material, and may include polyimide as a representative polymer material.

Next, the entire surface of the substrate 100 on which the diffusion barrier 102 is formed is treated with oxygen plasma so that the surface of the substrate 100 is hydrophilic.

Subsequently, one of the polymer materials emitting red, green, and blue light is selected on the substrate 100 subjected to the oxygen plasma treatment, and then the polymer is coated by spin-coating. The organic film 104 is formed. In this case, the coated polymer organic film 104 generally has a hydrophobic property and exists between the diffusion barriers 102.

Next, as shown in FIG. 2B, a stamp 106 is formed on the top surface of the substrate 100 coated with the polymer organic film 104 to form a concave-convex shape.                     

The stamp 106 is made of a hydrophobic polymer material, and the convex pattern A in the concave-convex shape is a portion for removing an unnecessary portion of the polymer organic film coated on the substrate 100.

In detail, a method of pushing up the convex pattern A of the stamp 106 to a portion of the plurality of pixels defined in the substrate 100 to be removed (hereinafter, referred to as a "lift-up method") will be described. If used, the unnecessary polymer organic film 104a is removed from the substrate 100 in a state where it is attached to the stamp 106.

At this time, since the substrate 100 has hydrophilicity and the polymer organic film 104 has hydrophobicity, the substrate 100 is easily separated from each other.

(In this step, the polymer organic film coating process is performed in the order of green, blue, and red.)

Therefore, the first polymer organic film pattern 108 remains only in the second pixel Gp and is removed in the remaining part.

Next, as shown in FIG. 2D, a substrate including the first polymer organic film pattern 108 is formed by spin coating a polymer organic material emitting blue light on the entire surface of the oxygen plasma treated substrate 100. The polymer organic film 110 is formed on the entire surface of the substrate 100.

Subsequently, when the convex pattern B of the stamp 106 is positioned in the second pixel Gp and the first pixel Rp, the lift-up process is performed. The polymer organic film patterns 108 and 110 remain only at the Gp and the third pixel Bp.

If the above-described process is repeated, as shown in FIG. 2E, the third polymer organic layer pattern 112 and the first polymer organic layer are respectively formed in the first, second, and third pixels Rp, Gp, and Bp. The film pattern 108 and the second polymer organic film pattern 110 are formed.
