Description

  The present invention relates to an organic functional device having a portion formed by applying and curing an organic material on a substrate, and more specifically, a convex portion so as to surround a portion constituting an organic functional element on the substrate. The present invention relates to an organic functional device having a provided structure.

  2. Description of the Related Art Conventionally, various organic functional elements such as organic transistors and organic light emitting elements using organic materials having a high molecular structure or a low molecular structure, and devices combining these have been developed. The organic functional element can be formed using a process of applying an organic material on a flexible substrate and curing it. Therefore, organic functional elements are expected to be applied to displays and electronic papers that are required to be thin, lightweight, and flexible.

  The organic layer of the organic functional element is usually formed by vapor deposition, spin coating, ink jet, or the like. Among these, in the ink jet method, the treatment can be performed at normal temperature and normal pressure, and partial treatment is possible. Therefore, a large vacuum device or the like is not required. Therefore, when an organic layer is formed by an ink jet method, it can be processed continuously, it is easy to cope with an increase in area, and costs can be reduced.

  An example of a method for forming an organic functional element using such an inkjet method is disclosed in Patent Document 1 and Patent Document 2 below. In the ink jet method, a droplet of an organic material solution is discharged from a nozzle to a predetermined region on a substrate and cured. In this case, a method of pre-treating the substrate surface in advance to form a hydrophilic portion and a hydrophobic portion, a method of forming an uneven microstructure such as a bank or groove for preventing liquid diffusion on the substrate surface, or A method using both of these is used.

  FIGS. 6A and 6B are a schematic plan view and a front sectional view of a conventional organic functional device obtained by a method of forming such a fine concavo-convex structure on a substrate.

  In the organic functional device 101, an organic TFT 103 and an organic light emitting element 104 are formed on a substrate 102. Here, first, the gate electrode 105 and the lower electrode 106 are formed over the substrate 102. Next, the gate insulating film 107 is formed. Thereafter, the source electrode 108 and the drain electrode 109 are formed. Next, the convex part 110 is formed using photosensitive resin. The convex portion 110 is provided so as to surround a portion where the organic TFT 103 is formed and a portion where the organic light emitting element 104 is formed. The convex portion 110 is formed by applying a photosensitive resin and patterning it using a photolithography technique.

  Thereafter, in the region where the organic TFT 103 is formed, an organic material is discharged by an ink jet method to form the organic thin film 111. In the region where the organic light emitting element 104 is formed, the organic light emitting layer 112 is formed by discharging and curing an organic material by the inkjet method. After the organic light emitting layer 112 is formed, the upper electrode 113 is formed.

  As described above, the organic functional device 101 in which the organic TFT 103 as the organic functional element and the organic light emitting element 104 are formed is obtained.

  However, in the manufacturing method described above, since the photolithography technique is used to form the convex portion 110, the manufacturing process tends to be complicated. Furthermore, when the miniaturization is promoted, the adhesive force of the convex portion 110 is reduced, and the convex portion 110 may be peeled off in a later process. When such peeling occurs, pixel defects or the like occur in the display.

  Note that it is considered that problems such as separation of the convex portions can be solved by forming predetermined convex portions on the substrate in advance and performing electrode formation on the substrate on which the convex portions are formed.

  For example, in Patent Document 3 below, a protrusion is provided in advance on a substrate, a source electrode and a drain electrode are formed so as to be separated by the protrusion, and then an organic material is applied. Discloses an organic transistor obtained.

However, in this organic transistor, the convex portion is merely provided as a separator for separating the source electrode and the drain electrode. Therefore, in the configuration described in Patent Document 3, when an organic material is applied by, for example, ink jetting, it has not been possible to prevent the droplets containing the organic material from spreading.
Japanese Patent Laid-Open No. 11-24604 JP 2005-215616 A JP 2005-64409 A

  As described above, in the step of forming the organic layer of the organic functional device 101 using the conventional ink jet method, a droplet containing an organic material is attached to a predetermined region on the substrate 102. It was necessary to form a portion, to form a convex portion 110 for preventing liquid diffusion, or to use both of them together. Therefore, the manufacturing process is complicated, a photolithography method using a large-scale facility must be used, the area can be easily increased, and the advantage of using an organic layer that can reduce the cost is great. It was damaged.

  Further, as the pattern becomes finer, the contact portion between the convex portion 110 and the portion to which the convex portion 110 is fixed becomes smaller, and thus the adhesive force of the convex portion 110 tends to be reduced. For this reason, defects due to peeling off of the convex portions 110 in a subsequent process have occurred and become a big problem.

  In addition, in the organic functional device 101, the organic TFT 103 and the organic light emitting element 104 are formed on the same substrate 102. However, the organic thin film 111 in the organic TFT 103 and the organic light emitting layer 112 in the organic light emitting element 104 are different. Usually, they are made of different materials and have different film thicknesses. Therefore, it is necessary to optimize the portion where the organic TFT 103 is formed and the portion where the organic light emitting element 104 is formed, whereas in the above manufacturing method, the convex portion 110 is integrated by photolithography. It is formed like this. Therefore, it has been difficult to form element forming portions suitable for the organic TFT 103 and the organic light emitting element 104 so as to have an optimum shape for each.

  An object of the present invention is an organic functional device that eliminates the above-mentioned drawbacks of the prior art and is provided with an organic functional element constituent part surrounded by a convex part on a substrate, and the organic functional element constituent part is It can be easily formed optimally for the organic functional element to be formed, and the protrusions do not peel off. Therefore, defects due to the peeling of the protrusions hardly occur, and it is easy to miniaturize and increase the area. It is an object of the present invention to provide an organic functional device that can cope with the above-described problem and can reduce the cost.

  The organic functional device according to the present invention includes a substrate having a frame-like convex portion surrounding the organic functional element constituent portion on one main surface, and the organic functional element constituent portion surrounded by the frame-shaped convex portion. An organic functional element having an organic material formed and an electrode provided so as to be electrically connected to the organic material, wherein the organic material is separated from a portion outside the convex portion by the frame-shaped convex portion. It is characterized by being separated.

  In the organic functional device according to the present invention, a substrate on which a frame-shaped convex portion is formed in advance on one main surface is used, and a portion surrounded by the frame-shaped convex portion is an organic functional element component. ing. Since the frame-shaped convex portion is formed in advance, a complicated process for forming the convex portion later is not required. And in the said organic functional element structure part enclosed by the frame-shaped convex part, the organic functional element which has an organic material and an electrode is formed, This organic material is from the part outside a convex part by the said convex part. It is separated. Therefore, the organic material can be reliably fixed to the organic functional element constituting portion surrounded by the convex portion by a droplet applying method such as an ink jet method.

  In a specific aspect of the organic functional element according to the present invention, each of the organic functional element constituent parts includes a plurality of organic functional element constituent parts surrounded by the frame-shaped convex part, At least one first organic functional element constituent part in which an organic functional element is configured and at least one second organic functional element that is an organic functional element different from the first organic functional element is configured. And a second organic functional component. In this case, each organic functional element component can be formed so as to be optimal for different organic functional elements. That is, the height of the convex part, the height of the bottom surface of the organic functional element constituent part surrounded by the convex part, and the like can be set to an optimum shape according to each organic functional element, and a plurality of them can be formed on one substrate. Each kind of organic functional element can be formed in an optimum shape.

  Therefore, more preferably, the shape of the first organic functional element constituent part is different from the shape of the second organic functional element constituent part.

  In another specific aspect of the organic functional element according to the present invention, an organic functional element constituent section in which a plurality of organic functional elements are configured is provided. As described above, in the present invention, at least one organic functional element constituent part in which a plurality of organic functional elements are configured may be provided, and one organic functional element constituent part is not necessarily one organic functional element constituent part. Need not be placed.

  The organic functional element configured in the organic functional device according to the present invention is not particularly limited. For example, an organic thin film transistor having a gate electrode, a gate insulating film, a source electrode, a drain electrode, and an organic material, a lower electrode, and an organic light emitting device. An organic light emitting device having a layer and an upper electrode can be exemplified.

  In another specific aspect of the organic functional device according to the present invention, a plurality of scanning lines provided on one main surface of the substrate and arranged at a distance from each other, and a direction in which the plurality of scanning lines extend A plurality of signal lines provided in a crossing direction, an organic thin film transistor configured according to the present invention, and an organic light emitting element are two-dimensionally arranged on one main surface of the substrate, Since the organic thin film transistor is connected to the signal line and the scanning line, according to the present invention, it is possible to provide an active display type display device in which the organic thin film transistor and the organic light emitting element are each optimally configured.

  In the organic functional device according to the present invention, an organic functional element having an organic material and an electrode is formed in the organic functional element constituent part surrounded by the frame-shaped convex part of the substrate on which the frame-shaped convex part is formed in advance. Yes. Therefore, peeling of the convex portions is unlikely to occur in the step of applying the organic material constituting the organic functional element, the step of forming the electrode, and the subsequent step. In addition, since the convex portions are only formed on the substrate in advance, even when the miniaturization is promoted, the manufacturing process is difficult to be complicated and the area can be easily increased. Therefore, it is difficult for the material constituting the convex portion to be peeled off, so that not only the defect is difficult to occur, but also it is possible to easily cope with miniaturization and large area, and to provide an inexpensive organic functional device. It becomes. And since the said convex part is previously formed in the board | substrate, the convex part of the shape according to the organic functional element comprised can be formed easily and cheaply. Therefore, the organic functional element component corresponding to the organic functional element can be reliably formed.

  Hereinafter, the present invention will be clarified by describing specific embodiments of the present invention with reference to the drawings.

  FIGS. 1A and 1B are a schematic plan view and a schematic partially cutaway front sectional view of an organic functional device according to a first embodiment of the present invention. The organic functional device 1 has a substrate 2. A frame-like convex portion 2 a is formed on the upper surface as one main surface of the substrate 2. The convex part 2a is formed so as to surround the plurality of organic functional element constituent parts 3 and 4, respectively. Therefore, the convex part 2 has a frame shape surrounding the organic functional element constituent parts 3 and 4.

  In the present embodiment, the bottom surface 4 a of the organic functional element component 4 is made lower than the bottom surface 3 a of the organic functional element component 3. This is because an organic TFT is formed as the first organic functional element in the organic functional element component 3 as described later, and the organic functional element component 4 is a second organic functional element different from the organic TFT. This is because a light emitting element is formed, and the organic functional element constituent parts 3 and 4 are each optimally shaped.

  In the organic functional element component 3, a gate electrode 5 is formed on the bottom surface, and a gate insulating film 6 is formed so as to cover the gate electrode 5. A source electrode 7 and a drain electrode 8 are formed on the gate insulating film 6. The source electrode 7 and the drain electrode 8 are extended from the inside of the organic functional element component 3 to the outside of the convex portion 2a through the side surface of the convex portion 2a. An organic thin film 9 is formed so as to cover the source electrode 7 and the drain electrode 8, thereby forming an organic TFT 11.

A protective film 10 made of polyparaxylene, SiO ₂ , SiN or the like is formed so as to cover the organic thin film 9.

  In the organic functional element component 4, a lower electrode 12 is formed on the bottom surface. The lower electrode 12 is electrically connected to the drain electrode 8 of the organic TFT. An organic light emitting layer 13 is formed on the lower electrode 12. An upper electrode 14 is formed so as to cover the organic light emitting layer 13. Here, an organic light emitting element 15 including the lower electrode 12, the organic light emitting layer 13 and the upper electrode 14 is formed. An insulating film 16 is formed to insulate the lower electrode 12 and the upper electrode 14 from each other. As is apparent from FIG. 1B, the source electrode 7 and the drain electrode 8 are extended outside the organic functional element component 3 or the organic functional element component 4, respectively. The convex part 2a has inclined side walls 2b, 2c facing the inside of the organic functional element constituent part 4, and top surfaces 2d, 2e. If the angle formed between the top surfaces 2d and 2e and the side surfaces 2b and 2c is obtuse, electrode breakage at the edge formed between the side surfaces 2b and 2c and the top surfaces 2d and 2e is unlikely to occur. Similarly, electrode breakage is unlikely to occur at portions corresponding to the edges of the bottom surfaces 3a, 4a of the organic functional element components 3, 4 and the side surfaces 2b, 2c inclined as described above. Therefore, it is desirable that the side surfaces 2b and 2c have an angle A shown in FIG. 1B, that is, an angle A formed between the side surfaces 2b and 2c and the top surfaces 2d and 2e is about 120 to 150 degrees.

  By the way, the depth direction dimension of the organic functional element constituent parts 3 and 4, that is, the distance between the bottom surfaces 3a and 4a of the organic functional element constituent parts 3 and 4 and the top surfaces 2d and 2e of the convex part 2a is organic. In TFT11, what is necessary is about 1-2 micrometers, and what is necessary is just about 3-4 micrometers on the organic light emitting element 15 side. Therefore, in the present embodiment, the bottom surface 3 a of the organic functional element component 3 is made higher than the bottom surface 4 a of the organic functional element component 4.

  In the organic functional device 1 of this embodiment, the convex part 2a and the organic functional element constituent parts 3 and 4 are formed on the substrate 2 so as to form the organic functional element constituent parts 3 and 4 in advance. Therefore, the organic functional element constituent parts 3 and 4 are formed in an optimal shape before the steps such as application of electrodes and organic materials for forming the organic TFT 11 and the organic light emitting element 15, respectively. Yes. Therefore, a complicated and large process is not required, and each organic functional element component 3, 4 is formed to have an optimum shape for each organic functional element.

  There is no particular limitation on the method of providing the convex portion 2a and the organic functional element constituent portions 3 and 4 on the substrate 2. For example, a method of forming a fine pattern on the substrate 1 made of a polymer material by a pattern transfer method such as a nanoimprint technique and thereby forming the organic functional element constituent parts 3 and 4 and the convex part 2a can be mentioned. Examples of such a nanoimprint method include a thermal nanoimprint method using heating, a photo nanoimprint method using photoreaction, and a nanoimprint method applying pressure.

  Moreover, you may prepare the board | substrate 2 with which the organic functional element structure parts 3 and 4 and the convex part 2a were previously provided by various molding methods, such as an injection molding method. In the injection molding method, the substrate 2 can be obtained by pouring a synthetic resin as a substrate material into a mold, heating, and cooling.

  Furthermore, as in a specific example described later, patterning is performed by coating a mold having a desired pattern with a polymer resin, raising the temperature, pressing the mold on another substrate, and releasing the mold. The substrate 2 may be obtained by transferring the obtained polymer resin film to the other substrate.

  In such a method using various molds and molds, the height of the bottom surfaces 3a and 4a and the inclination angles of the side surfaces 2b and 2c of the convex portions can be set at the time of producing the molds and molds. Arbitrary shapes of organic functional element constituent parts 3 and 4 can be easily formed.

  When forming the organic functional element constituent parts 3 and 4 and the convex part 2a on the substrate 2 by the pattern transfer method using the photoreaction, for example, a photoreactive resin is applied on a flat substrate. Then, after pressing a mold having a desired pattern against the photoreactive resin layer, for example, the photoreactive resin is cured by irradiating ultraviolet rays, and then the mold is released. Then, the pattern may be transferred to the substrate by dry etching using the formed pattern as a mask. When pattern transfer is performed by etching, the above steps may be repeated, thereby forming the side surfaces 2b and 2c having a desired inclination angle.

  Next, with reference to FIGS. 2A to 2D and FIGS. 3A and 3B, an example of a specific method for manufacturing the organic functional device 1 of the above embodiment will be described.

  First, as shown in FIG. 2A, a polymer resin substrate 2 made of PMMA is prepared. Thereafter, the mold 21 is pressed against the upper surface of the substrate 2 under heating at about 200 ° C. On the lower surface of the mold 21, a pattern 21a corresponding to the organic functional element constituent parts 3 and 4 and the convex part 2a is formed. Under this heating, the pattern 21 a is transferred to the upper surface of the substrate 2 by pressing the mold 21 against the substrate 2 from the pattern 21 a side. After the transfer, the mold 21 is separated from the substrate 2 to obtain the substrate 2 on which the convex portions 2a and the organic functional element constituent portions 3 and 4 are formed as shown in FIG.

  Thereafter, as shown in FIG. 2C, the gate electrode 5 made of Al having a thickness of several hundreds nm and the lower part made of ITO are formed on the upper surface of the substrate 2 by RF sputtering and vapor deposition using a metal mask, respectively. Electrode 12 is formed.

Next, as shown in FIG. 2D, a gate insulating film 6 and an insulating film 16 are formed by forming a SiO ₂ film having a thickness of 30 nm to 150 nm by sputtering and then patterning by photolithography. . In the patterning by the photolithography, the patterning is performed so that the SiO ₂ film does not exist on the lower electrode 12.

  Next, as shown in FIG. 3A, Au / Cr alloy is pattern-deposited using a metal mask, and the source electrode 7 and the drain electrode 8 are formed in the organic functional element component 3. The distance of the channel portion between the source electrode 7 and the drain electrode 8, that is, the distance between the electrodes may be several tens of nm. In this step, at the same time, the extended portion of the drain electrode 8 is provided so as to be electrically connected to the lower electrode 12 of the organic functional element constituting unit 4.

  Thereafter, as shown in FIG. 3B, the organic thin film 9 is formed by ejecting the organic material to the organic functional element constituting section 3 by the ink jet method.

  Further, after the organic thin film 9 is formed or before the organic thin film 9 is formed, an organic material solution that constitutes the organic light emitting layer 13 is applied to the organic functional element constituent unit 4 by an ink jet method to form the organic light emitting layer 13. To do.

  The organic thin film 9 and the organic light emitting layer 13 are both formed by discharging an organic material solution by an ink jet method as described above, but the organic functional element constituent parts 3 and 4 are formed by the convex part 2a as described above. Since they are separated, the organic material solution can be reliably fixed to the organic functional element constituent part 3 or the organic functional element constituent part 4.

  That is, the movement to the other organic functional element part beyond the convex part 2a of the organic material can be prevented.

  In forming the organic light emitting layer 13, for example, a method in which polyethylene dioxythiophene (PEDOT), which is a conductive material, is applied by an ink jet method, and then an organic material layer that becomes a light emitting layer is formed by the ink jet method. it can. In that case, the organic film to be the light emitting layer may be formed of a plurality of layers.

  Finally, an upper electrode 14 made of Al having a thickness of 300 nm and a protective film 10 made of polyparaxylene resin and having a thickness of 500 to 1000 nm are formed by vapor deposition.

  When forming each electrode by vapor deposition, a lift-off method may be used.

  As is clear from the above manufacturing method, in this embodiment, after preparing the substrate 2 on which the organic functional element constituent parts 3 and 4 and the convex part 2a are formed, a complicated uneven pattern is formed on the substrate. No photolithographic process is required. Therefore, the manufacturing process can be simplified and the cost can be reduced.

  In addition, the organic functional element constituent parts 3 and 4 and the convex parts 2 a corresponding to the organic functional element constituent parts 3 and 4 can be formed on the substrate 2 in advance. Therefore, it is possible to easily optimize the organic TFT 11 and the organic light emitting element 15 as the organic functional element constituent unit. Moreover, since peeling in the post-process of the convex part 2a is difficult to occur, defects are also unlikely to occur.

  The material constituting the substrate 2 is not limited to the PMMA, and various polymer resins such as polyimide and polycarbonate can be suitably used. In the case of using a polymer resin, it is preferable to use a polymer resin that can withstand the heating temperature when forming an organic TFT or an organic light emitting element. As such a polymer resin, the above PMMA, polyimide, polycarbonate, etc. having a melting point and a softening point of 200 to 250 ° C. or less can be suitably used.

  Moreover, the board | substrate 2 may be comprised with materials other than resin, for example, appropriate insulating materials, such as glass and ceramics.

In addition, a substrate made of a metal thin film may be used as the substrate 2. In that case, an insulating layer may be formed on the entire surface of the substrate made of the metal thin film. Examples of the insulating layer include an insulating resin such as polyimide, and an insulating oxide film such as SiO _2. The thickness of the insulating layer is not particularly limited, but may be about 150 to 5000 nm.

  If the substrate 2 is made of an opaque material, the light may be extracted from above the organic light emitting element 15. In that case, the upper electrode 14 may be formed of a transparent electrode.

  The electrode material in the organic TFT 11 is not limited to Al, and other metals or alloys such as Ta can be used.

  Furthermore, in addition to vapor deposition and sputtering, an electrode such as the gate electrode 5 may be formed by a conductive film formed by a printing method.

  As for the gate insulating film 6, a part of the electrode material constituting the gate electrode 5 may be oxidized to form a gate insulating film.

  In the above embodiment, the lower electrode 12 is formed of a transparent electrode. However, as a material for forming the transparent electrode, IZO or the like may be used in addition to ITO.

  FIGS. 4A and 4B are a schematic plan view of an organic functional device according to a second embodiment of the present invention and a partially cutaway sectional view taken along line BB in FIG.

  The organic functional device 31 of the second embodiment has a substrate 32. Here, on the substrate 32, frame-shaped convex portions 32a and 32b are formed in advance, whereby organic functional element constituting portions 33 and 34 are formed. In the present embodiment, the organic functional element constituent unit 33 and the organic functional element constituent unit 34 are arranged in a matrix of 2 rows × 2 columns, that is, two-dimensionally. A plurality of scanning lines 35a and 35b extending in the row direction are formed, and a plurality of signal lines 36a and 36b are formed so as to extend in the column direction. Further, power supply lines 37a and 37b are formed in a direction extending in parallel with the signal lines 36a and 36b.

  Similar to the organic functional element constituent parts 3 and 4 of the first embodiment, the organic functional element constituent parts 33 and 34 are formed surrounded by frame-shaped convex parts.

  In the present embodiment, a selection transistor 38 and a drive transistor 39 are formed in the organic functional element configuration unit 33. The selection transistor 38 includes a gate 38a, a gate insulation 38b, a source electrode 38c, a drain electrode 38d, and an organic thin film 38e. The drive transistor 39 also has a similar electrode structure. Here, both the selection transistor 38 and the drive transistor 39 are organic thin film transistors.

  The organic thin film 38e is not necessarily shared by the selection transistor 38 and the driving transistor 39. However, since the same organic thin film is used in the present embodiment, the same is used in the organic functional element component 33 by the inkjet method. The organic thin film 38e can be formed only by discharging the organic material solution. Reference numeral 40 denotes a protective film.

  As described above, a plurality of types of organic functional elements may be configured in one organic functional element configuration unit 33. In addition, a plurality of organic functional elements of the same type may be configured in one organic functional element configuration unit 33.

  On the other hand, the organic functional element constituent unit 34 is configured in the same manner as the organic functional element constituent unit 4 in which the organic light emitting element shown in the first embodiment is configured. And the organic light emitting element is comprised by the organic functional element structure part 34 similarly to the organic functional element 4 of 1st Embodiment.

  The power supply lines 37a and 37b are connected to an organic light emitting element provided in the organic functional element constituting unit 34, and are provided to supply power to the organic light emitting element and to emit light from the organic light emitting element. Now, the drive power supply voltage 30V is applied to the power supply lines 37a and 37b. As a scanning signal for turning on the scanning lines 35a and 35b, for example, when a voltage signal of 10V is applied, the selection transistor 38 connected to the scanning line 36b is turned on, and for example, 10V from the signal line 36a. Is applied to the gate electrode of the drive transistor 39. For this reason, the driving transistor 39 operates, current is supplied from the power supply line 37a, and the organic light emitting element operates to emit light.

  When a voltage of, for example, 30 V is applied to the scanning line 35a as an off-condition voltage signal, the selection transistor 38 connected to the scanning line 35a does not operate and the signal voltage of the signal line 36a is not affected. Therefore, the light emission of the organic light emitting element at an arbitrary position can be controlled by the combination of the scanning lines 35a and 35b and the signal lines 36a and 36b.

  The scanning lines 35a and 35b, the signal lines 36a and 36b intersecting with the scanning lines 35a and 35b, and the power supply lines 37a and 37b are three-dimensionally crossed and insulated with an insulating film interposed therebetween. ing.

  5A and 5B are a plan view showing an organic functional device according to a third embodiment of the present invention and a cross-sectional view taken along the line CC in FIG.

  In the organic functional device 41 of the third embodiment, a plurality of organic functional element constituent parts 43 and 44 are provided on a substrate 42. Each of the organic functional element constituent parts 43 and 44 is provided by forming a frame-like convex part 42a.

  In the present embodiment, an organic thin film transistor 45 is formed in the organic functional element configuration unit 43, and an organic thin film transistor 46 is formed in the organic functional element configuration unit 44. The organic thin film transistors 45 and 46 are field effect type organic thin film transistors having gate electrodes 45a and 46a, gate insulating films 45b and 46b, source electrodes 45c and 46c, drain electrodes 45d and 46d, and organic thin films 45e and 46e, respectively. . Here, one organic thin film transistor 45 is configured using a p-type organic thin film semiconductor material, and the organic thin film transistor 46 is configured using an n-type organic thin film semiconductor material. In this way, organic thin film transistors having different polarities may be formed in the plurality of organic functional element constituent parts 43 and 44, respectively.
