[0157] The opposing electrode 230 may be provided on the connected pixel PXc located on the second display area DA2. However, the second display area DA2 is the connected pixel area PA2 where the connected pixel PXc is located, It includes a second transmission region TA2 and a third transmission region TA3, but a portion of the counter electrode 230 is second transmission It is not present in some regions corresponding to region TA2 and the third transparent region TA3. Here, front In the case of an optical display device, light is emitted towards the counter electrode 230, but the counter electrode 230 is transparent It goes without saying that the transient rate will decrease in some cases. Therefore, the second transmission region TA2 and In the region corresponding to the third transmission region TA3, by not having a counter electrode 230 This makes it possible to improve the transmittance of the second transmission region TA2 and the third transmission region TA3.

[0160] Figures 9 and 10 are plan views showing a portion of the first display area according to one embodiment of the present invention. .

[0161] Referring to Figures 9 and 10, as mentioned above, the first display area DA1 is the auxiliary pixel area P A1 and the first transmission region TA1 are included, and the auxiliary pixel region PA1 has an auxiliary pixel PXa. The auxiliary pixel region PA1 is, as shown in Figure 9, the first pixel region PA1-1 and the second pixel region PA1-2 is included, and multiple first pixels PXa1 are arranged in the first pixel region PA1-1.

The data lines are extended and intersect with the first direction DR1, for example, along the orthogonal second direction DR2. It is also extended. At this time, on the first pixel region PA1-1, there are other signal lines PL, It goes without saying that EL, SL-1, and VL (Figure 7) are also included.

[0164] Some of the data lines and scan lines can be located on the first transparent region TA1. In this case, for example, the scan line is used to improve the transmittance of the first transmission region TA1. It may have a bypass region that is positioned to bypass the edge of the over-region TA1. The bypass region also applies to the other signal lines PL, EL, SL-1, and VL (Figure 7). .

[0165] Multiple first pixels PXa1 arranged on the first pixel region PA1-1 are one first pixel region The device may be equipped with a first counter electrode 230a integrally formed on region PA1-1.

[0166] Multiple second pixels PXa2 arranged on the second pixel region PA1-2 are one second pixel region The device may be equipped with a second counter electrode 230b integrally formed on region PA1-2.

[0167] The first pixel region PA1-1 and the second pixel region PA1-2 are arranged on different lines from each other. This is also possible. In such a case, the first pixel region PA1-1 and the second pixel region PA1-2 are the first They may be arranged to surround the transparent region TA1. That is, the first pixel region PA1-1 The second pixel region PA1-2 may be arranged in a zigzag pattern.

[0168] The first opposing electrode 230a and the second opposing electrode 230b are, respectively, in the first pixel region PA1-1 and It is arranged in correspondence with the second pixel region PA1-2, but in some regions they are in contact with each other.

[0169] In the case described above, the first counter electrode 230a and the first contact region CTA1 are connected via the first contact region CTA1. The two opposing electrodes 230b are connected to each other and are positioned on the first display area DA1. This can improve the increase in resistance at the counter electrodes 230a and 230b.

[0170] Figures 11 and 12 show a portion of the manufacturing process of a display panel according to one embodiment of the present invention. This is a schematic cross-sectional view. Figure 13 shows a schematic cross-section cut along the line B-B' in Figure 9. This is a cross-sectional view.

[0171] Referring to Figures 11 to 13, an insulating layer IL on which the pixel circuit PC is located is on the substrate 100. The first pixel electrode 210a and the second pixel electrode 21 are formed and electrically connected to the pixel circuit PC. 0b is formed. The first pixel electrode 210a is placed on the first pixel region PA1-1, and the second The pixel electrode 210b is positioned on the second pixel region PA1-2.

[0172] The central portions of the first pixel electrode 210a and the second pixel electrode 210b are exposed. A pixel definition film 119 having an opening is formed. On the first pixel electrode 210a, a first intermediate layer 220a is formed, and on the second pixel electrode 210b, A second intermediate layer 220b is formed there. The first intermediate layer 220a and the second intermediate layer 220b are shown in the figure. It may be understood that this is the same material as the intermediate layer 220 described in section 8.

[0173] Subsequently, the first counter electrode 230a is placed on the first intermediate layer 220a and the second intermediate layer 220b. And a second counter electrode 230b may be formed. In this embodiment, the first counter electrode 23 0a and the second opposing electrode 230b may be formed through different processes. In order to form the first counter electrode 230a and the second counter electrode 230b, the same first The first mask sheet 422A of the mask assembly can be used. That is, the first opposing After forming the electrode 230a, at least one of the first mask assembly and the substrate 100 is used. After moving to a position different from the initial position, the second opposing electrode 230b is formed on the substrate 100. This is possible. In another embodiment, the first counter electrode 230a forms the second counter electrode 230b. After completion, at least one of the mask assembly and the substrate 100 is moved to a position different from the initial position. It is also possible to move it and then form it on the substrate 100. For the sake of explanation below, Then, after the formation of the first counter electrode 230a, the position of the substrate 100 is moved, and the second counter electrode 230 We will explain in detail, focusing on the case where b is formed.

[0174] Specifically, as shown in Figure 11, the first counter electrode 230a is formed on the first intermediate layer 220a. The first counter electrode 230a is positioned at the first opening 422A-1 of the first mask sheet 422A. The vapor-deposited material that has passed through may be deposited onto the substrate 100 to form a structure. After that, as shown in Figure 12 Then, move the substrate 100 to the left side of Figure 11, and place the second counter electrode 230 on the second intermediate layer 220b. b is formed. The second opposing electrode 230b is in the first opening 422 of the first mask sheet 422A. It may be manufactured via A-1.

[0175] Referring to Figure 13, the first counter electrode 230a and the second counter electrode formed as described above... The electrodes 230b make surface contact with each other in the first contact region CTA1. First counter electrode 230a The fact that the first counter electrode 230a and the second counter electrode 230b are in surface contact means that the first counter electrode 230a and the second counter electrode No layer is interposed between electrode 230b and the first counter electrode 230a. It is understood that the second opposing electrode 230b is stacked and comes into contact with each other.

[0176] In the first contact region CTA1, the second counter electrode 230b is the first counter electrode 230a It is positioned on top. This means that the second counter electrode 230b is in a later process than the first counter electrode 230a. This means that it is formed by the first. In another embodiment, the second opposing electrode 230b is the first When formed by a process after the counter electrode 230a, the first contact region CTA1 In this case, the first counter electrode 230a may be placed on the second counter electrode 230b. In the contact region CTA1, the first counter electrode 230a and the second counter electrode 230b are in surface contact. As a result, the region where only the first counter electrode 230a or the second counter electrode 230b is located Furthermore, it may be formed to a thickness of approximately twice or less. Also, the first contact region CTA1 is It is desirable that they are not placed on the light-emitting regions of the first pixel PXa1 and the second pixel PXa2. In this case, the "light-emitting regions" of the first and second pixels are formed on the pixel definition film 119, respectively The first aperture OP1 exposes the central part between the first pixel electrode 210a and the second pixel electrode 210b. The first contact region CTA1 may be defined as the first and second opening OP2. The first aperture OP1 and the second aperture OP2 formed on the pixel definition film 119 are not superimposed. They may be provided in this manner.

[0177] The larger the area of ​​the first contact region CTA1, the larger the area of ​​the first counter electrode 230a and the second counter electrode. It is advantageous to lower the resistance of pole 230b. However, as mentioned above, the first If the area of ​​the contact region CTA1 is made larger than a certain size, the light-emitting region of pixels PXa1 and PXa2 will be larger. This superimposition causes a decrease in the light emission quality of pixels PXa1 and PXa2.

[0178] Therefore, the area of ​​the first contact region CTA1 is equal to the area of ​​the first opening OP1 and the second opening OP2. It may be formed to the extent that it does not obstruct anything.

[0179] Referring to both Figure 11 and Figure 13, the first transparent region TA1 is the first pixel region PA1-1 In contrast, display elements such as organic light-emitting diodes (OLEDs) and the pixels electrically connected to them It does not include the path PC. Furthermore, such a first transparent region TA1 is arranged on the substrate 100. It may also be defined as a region from which a portion of the layer has been removed.

In that case, the third pixel region PA2-1 A third opposing electrode 230c is positioned in the fourth pixel region PA2-2, and a fourth opposing electrode 2 30d may be placed.

[0183] In the case described above, the third opposing electrode 230c and the fourth opposing electrode 230d have different shapes from each other. It may be so. For example, the third opposing electrode 230c may be the first opposing electrode 230a or the second opposing electrode. Electrode 230b is identical, and the fourth counter electrode 230d is identical to the third counter electrode 230c. No. In particular, the third opposing electrode 230c is square, and the fourth opposing electrode 230d is rectangular. It may also be in this form. Furthermore, the fourth opposing electrode 230d may have at least two or more third opposing electrodes. The location where electrode 230c is connected may be the same as, or larger than, that location.

[0184] The third display area DA3 may include the main pixel area PA3. A main counter electrode 230e may be placed there.

[0185] In the case described above, the third counter electrode 230c and the fourth counter electrode 230d are the main counter electrode When pole 230e is formed, it may be formed at the same time.

[0186] The third opposing electrode 230c and the fourth opposing electrode 230d may each be provided in multiple quantities. Multiple third opposing electrodes 230c may be arranged so as to be spaced apart from each other. Multiple fourth opposing electrodes 230d may be arranged so as to be spaced apart from each other. In that case, each of the multiple third opposing electrodes 230c and the multiple fourth opposing electrodes 230d These may be arranged in a line in the X direction of Figure 14. Also, each third opposing electrode 230c and each fourth The counter electrodes 230d may be arranged in the Y direction in Figure 14 and connected to one another.

[0187] The third opposing electrode 230c is connected to the first opposing electrode 230a or the second opposing electrode 230b. It may be done. At that time, the third opposing electrode 230c is the first opposing electrode 230a or the second opposing electrode. It may include a second contact region CTA2 superimposed on electrode 230b. In the second contact region CTA2, the third counter electrode 230c is located in the first counter electrode 230a Alternatively, it makes surface contact with the second opposing electrode 230b. Also, in the second contact region CTA2 The third opposing electrode 230c is positioned above the first opposing electrode 230a or the second opposing electrode 230b. The third counter electrode 230c is placed between the first counter electrode 230a and the second counter electrode. It may be positioned below pole 230b. For the sake of explanation below, the second contact will be referred to as follows. In region CTA2, the third counter electrode 230c is positioned above the second counter electrode 230b. I will explain in detail, focusing on the cases where this occurs.

[0188] In the case described above, the thickness of the second contact region CTA2 is the same as that of the second counter electrode 230b. The thickness may be greater than the thickness of the third opposing electrode 230c. For example, the second contact region CTA2 The thickness is approximately twice the thickness of the second opposing electrode 230b or the third opposing electrode 230c. It's okay to become one.

[0189] In the case described above, the third opposing electrode 230c and the fourth opposing electrode 230d, which are connected to each other, , it may include a third contact region CTA3 that overlaps with each other. In such a case, the third The thickness of the contact area CTA3 is, as mentioned above, the thickness of the third opposing electrode 230c. , or identical to or similar to one of the thicknesses of the fourth opposing electrode 230d In other words, in the third contact region CTA3, the third opposing electrode 230c and the fourth opposing electrode Since electrode 230d is formed at the same time, the third counter electrode 230c or the fourth counter electrode 23 One of the 0d is the other of the third counter electrode 230c or the fourth counter electrode 230d It makes direct contact with the upper surface. In such a case, the third opposing electrode 230c and the fourth opposing electrode 230d They are in surface contact with each other. For the sake of explanation, as illustrated in Figure 15, This explanation will focus on the case where the fourth counter electrode 230d is positioned on the third counter electrode 230c. ru.

[0190] The fourth opposing electrode 230d is also connected to the main opposing electrode 230e. The counter electrode 230d is separated from the main counter electrode 230e in part, and the other part is connected to the main electrode. The fourth counter electrode 230d may be directly connected to the counter electrode 230e. In that case, the fourth counter electrode 230d is "T It may be formed in the shape of a " and connected to the main counter electrode 230e.

This is also acceptable. For example, in the first pixel region PA1-1, the first pixel PXa1 is placed, and the second pixel A second pixel PXa2 may be placed in region PA1-2. Also, a third pixel region PA2 -1 contains the third pixel PXc1, and the fourth pixel region PA2-2 contains the fourth pixel PXc 2 may be placed.

[0200] The shape of the first aperture 422A-1 is either the first pixel region PA1-1 or the second pixel region PA1 -2 may be formed to correspond to -2. For example, the shape of the first opening 422A-1 is long It may include a square, rectangular or rhombus shape. In the aforementioned case, the first opening 422A-1 The vapor-deposited material that passes through is deposited onto the substrate 100 to form a first counter electrode or a second counter electrode. This is possible. In such cases, if there are multiple first openings 422A-1, Several first openings 422A-1 allow the deposited material that has passed through each first opening 422A-1 to reach the substrate. After being deposited onto 100, they are arranged so as to be sufficiently separated from each other so that they do not connect to one another. That's good too.

[0201] The first opening 422A-1 described above corresponds to the first display area DA1 of the substrate 100. The region may be arranged to form a counter electrode. In particular, the first opening 422A-1 They may be placed only in the first region AR1-1 of the first mask sheet 422A. In this case, a separate opening is provided in the second region AR1-2 of the first mask sheet 422A. It may be in a certain state.

The third opening 422B-2 is different from the second opening 422B-1. It may be formed in such a way. For example, the third opening 422B-2 is formed in a way that is greater than the second opening 422B-1. These are also formed in large quantities. In such cases, the third opening 422B-2 is formed in at least two or more locations. The second opening 422B-1 may be formed to correspond to the second opening 422B-1. The third opening 422B-2 may be positioned to be separated from each other. The second mask sheet 4 is positioned between the second opening 422B-1 and the third opening 422B-2. The first width W1 of 22B is formed to be very narrow, thereby connecting the second opening 422B-1 and the The deposited material that passes through the three openings 422B-2 and the substrate 100 is also deposited They are connected to each other.

[0206] The fourth opening 422B-3 may be connected to the third opening 422B-2. In that case, The second mask sheet is positioned between the fourth opening 422B-3 and the third opening 422B-2. The second width W2 of 422B is formed to be wider than the first width W1, which is one of the fourth opposing electrodes. Only the part may be connected to the main counter electrode.

[0210] The deposition source 450, after the deposition material has been contained, vaporizes the deposition material or raises it. It can be heated and supplied to the chamber 410. At that time, the deposition source 450 is inside A heater may be included, and the operation of the heater heats the deposition material inside the deposition source 450. By doing so, the deposited material can be melted or sublimated. In such cases, the deposition source 450 may be placed in the center or corner of the chamber 410. i. In the following explanation, for the sake of convenience, the deposition source 450 is located at the corner of the chamber 410. This will be explained in detail, focusing on cases where the character is placed in a specific location.

At that time, the pressure adjustment unit 480 is connected to the connecting pipe 4 connected to the chamber 410. 81 and a pump 482 located in the connecting pipe 481 may also be included.

[0214] The display device 1 can be manufactured using the display device manufacturing apparatus 400. At that time, The manufacturing apparatus 400 for the display device is not limited to the embodiments described above, but also to the embodiments described below. A display device 1 can be manufactured by this. However, in the following, for the sake of explanation, The display device manufacturing apparatus 400 is a pixel area of ​​a display panel (not shown) as shown in Figure 14. This section will explain in detail, focusing on the manufacturing process. In the following, the same reference numerals as in Figure 14 will be used in the same way. One component is shown.

[0215] Specifically, a substrate 100 on which an insulating layer (not shown) is formed, and the first mask assembly 42 0A can be placed inside chamber 410. At that time, thin-film transistor (illustrated) (not shown) and an organic light-emitting element (not shown), the pixel electrode (not shown) and the organic light-emitting layer ( (Not shown) may be in a state where a shape is formed.

[0216] The substrate 100 and the first mask assembly 420A are supported by the first support part 430 and the second support part, respectively. After being placed on 440, the substrate 100 and the first mask assembly 4 are viewed via the vision unit 470. 20A can be photographed. After that, the substrate 100 and the first mask assembly 420A are arranged. They can be arranged in rows.

[0217] When the deposition source 450 is activated and supplies the deposition material, the deposition material will be deposited onto the first mask sheet. The first aperture 422A-1 of 422A passes through the organic light-emitting layer and pixel definition film of the substrate 100. It may be deposited on top. At that time, the deposited material that has passed through the first opening 422A-1 is as described above. As shown in the section, the first counter electrode 230a or the second counter electrode 230b is formed. Yes, it is possible. In the following, for the sake of explanation, we will assume that the first counter electrode 230a is formed. I will explain the details in the center.

[0218] As mentioned above, when deposition is performed, the first counter electrode 230a may be arranged in a single line. Good. Multiple such columns may be provided and arranged to be spaced apart from one another.

[0219] Once the aforementioned process is complete, at least of the substrate 100 and the first mask assembly 420A One position can be varied. For example, the position of the first mask assembly 420A can be fixed. After that, the position of the substrate 100 can be varied. In another embodiment, the substrate 10 After fixing the position of 0, it is also possible to vary the position of the first mask assembly 420A. Furthermore, in another embodiment, the position of the substrate 100 and the position of the first mask assembly 420A It is also possible to make all of the positions variable. In the following, for the sake of explanation, the first The position of the mask assembly 420A is fixed, and the position of the circuit board 100 is then varied. I will explain it in detail to my mind.

[0220] When the position of the substrate 100 is varied, the first opening 422A is such that the first counter electrode 230a It may be positioned to correspond to the portion of the substrate 100 that has not been formed. That is, the first opening The opening 422A-1 may be positioned between adjacent first opposing electrodes 230a.

[0221] After varying the position of the substrate 100, if the deposition material is supplied from the deposition source 450, deposition will occur. The material passes through the first opening 422A-1 and is deposited on the substrate 100. At that time, The deposited material that passes through the opening 422A-1 is deposited on the substrate 100 and the second counter electrode 230 b can be formed. The second opposing electrode 230b is positioned between the first opposing electrodes 230a. They may be connected via the first contact area CTA1.

It is possible.

[0224] Specifically, when the third counter electrode 230c is formed on the substrate 100, the third counter electrode 23 0c may be connected to either the first counter electrode 230a or the second counter electrode 230b. Specifically, when a third counter electrode 230c is formed, the third counter electrode 230c and the Between one of the first opposing electrode 230a or the second opposing electrode 230b, there is a second contact A first contact region CTA2 is formed. At that time, in the second contact region CTA2, the first A third counter electrode 230 is placed on the upper surface of either the counter electrode 230a or the second counter electrode 230b. c may be provided. In other embodiments, a third opposing electrode 230c and a fourth opposing electrode 23 First, the 0d and the main counter electrode 230e are formed on the substrate 100, and the first counter electrode 230a and When the second opposing electrode 230b is formed sequentially, the upper surface of the third opposing electrode 230c has the first pair It is also possible to place either the forward electrode 230a or the second counter electrode 230b.

[0225] As mentioned above, when the third opposing electrode 230c and the fourth opposing electrode 230d are formed, The second mask sheet 422B between the second opening 422B-1 and the third opening 422B-2 Because the width W1 is sufficiently narrow, the third opposing electrode 230c and the fourth opposing electrode formed on the substrate 100 The opposing electrodes 230d may be superimposed and connected to each other.

[0226] Therefore, the opposing electrodes placed on the substrate 100 are in contact with each other through their respective contact areas. It may be continued.

[0227] Furthermore, the display device manufacturing apparatus 400 connects the opposing electrodes placed in the display area DA to each other. This prevents pixels in each display area from failing to emit light.
