In the laser irradiation step, the first electrode layer is formed along the frame region so as to surround the first window. A laser may be irradiated. Thereby, in the light emission area of one pixel, the area to be darkened can be made as small as possible.

  In the step of forming the first electrode layer, a plurality of conductive portions provided independently of each other corresponding to the plurality of windows and a line portion that conducts the plurality of conductive portions are the first electrode layer. May be formed. In that case, the line portion of the first electrode layer may be divided in the laser irradiation step.

  Hereinafter, embodiments of the present technology will be described with reference to the drawings.

  [First embodiment]

  FIG. 1 is a plan view showing one pixel of a display device using an organic EL as a light emitting device according to the first embodiment of the present technology. FIG. 2 is a cross-sectional view taken along the line AA in FIG. FIG. 1 is shown by a cross section taken along line BB in FIG. 1 and 2 show the display device 100 in a state where foreign matter P is mixed.

  “One pixel” means a sub-pixel corresponding to one color when the display device 100 adopts a color display method.

  The display device 100 is a top emission type organic EL display device. As shown in FIG. 2, the display device 100 includes a substrate 11, a TFT (Thin Film Transistor) layer 12 that is a driving layer formed on the substrate 11, and a planarization layer 13 formed on the TFT layer 12. Is provided. The drive substrate 10 is configured by the substrate 11 and the TFT layer 12. Alternatively, the drive substrate 10 may be configured by the substrate 11, the TFT layer 12, and the planarization layer 13.

  The TFT layer 12 is provided with a drive circuit having a TFT (not shown). The planarization layer 13 is mainly formed of an interlayer insulating film, and has a contact plug (not shown).

  The display device 100 includes a first electrode layer (anode) 21 formed on the planarization layer 13 and a window layer 20 formed on the first electrode layer 21. In addition, the display device 100 includes an organic layer 23 that is an electroluminescent layer formed on the first electrode layer 21 and the window layer 20, and a second electrode layer (cathode) 22 formed on the organic layer 23. .

  The first electrode layer 21 is formed so as to be conductive for each pixel. As shown in FIG. 1, the first electrode layer 21 has a contact hole 21a and a conductive material formed in the contact hole 21a. The conductive material is connected so as to conduct to a contact plug (not shown) provided on the planarizing layer 13.

  The window layer 20 has a plurality of windows 20a for each pixel, for example, four windows 20a in the present embodiment. These windows 20a are provided through the window layer 20 in the stacking direction of the layers. The window layer 20 has a frame region 20b that forms these windows 20a. In the present embodiment, the frame region 20b is formed so that the substantially rectangular windows 20a are arranged in a matrix.

  The organic layer 23 is typically configured by laminating a hole injection layer, a hole transport layer, a light emitting layer, an electron transport layer, and an electron injection layer in this order from the first electrode layer 21 side. The light emitting layer has a region that emits light of one color in one pixel among three colors of red, green, and blue (RGB).

  The organic layer 23 may be provided on the first electrode layer 21 at least in the window 20 a of the window layer 20 so as to be connected to the first electrode layer 21. However, in order to facilitate the manufacture of the display device 100, the organic layer 23 is also formed on the frame region 20b so as to be continuous with the organic layer 23 in the window 20a.

  The second electrode layer 22 functions as a common electrode.

  The display device 100 includes a sealing material 16 disposed on the second electrode layer 22. The sealing material 16 is a concept including, for example, a sealing resin layer 14 as a first sealing material and a sealing substrate 15 as a second sealing material. A color filter layer 19 is provided between the sealing resin layer 14 and the sealing substrate 15.

  The color filter layer 19 includes, for each pixel, an RGB color filter 17 and a black matrix 18 that partitions the area of the color filter 17 so as to correspond to the pixels.

  Film formation of each layer (TFT layer 12 to sealing resin layer 14) included in the display device 100 is performed using a known film formation technique by atmospheric pressure vapor deposition, CVD (Chemical Vapor Deposition) or PVD (Physical Vapor Deposition). . The patterning of each layer may be performed by a known patterning technique such as photolithography and etching.

  The window layer 20 and its window 20a are also typically formed by the above-described film formation technique and patterning technique.

  The color filter layer 19 may be formed by a patterning technique by photolithography and etching, or may be formed by a technique such as mask vapor deposition, ink jet printing, or screen printing.

After the color filter layer 19 is formed, the sealing substrate 15 is attached to the processing target device including the drive substrate 10 to the color filter layer 19. The sealing (mounting) step with the sealing substrate 15 is typically performed in a vacuum in order to remove excess air and moisture contained in the device to be processed.
Alternatively, as a manufacturing process according to another embodiment, after the color filter layer 19 is formed on the sealing substrate 15, the device on the sealing substrate 15 side and the drive substrate 10 formed up to the sealing resin layer 14, for example. The device on the side may be attached. In that case, an adhesive layer (not shown) may be formed on the sealing substrate 15, and the color filter layer 19 may be formed on the adhesive layer.

  The repair process of the display device 100 configured as described above will be described.

  The repair process according to the present embodiment is typically performed after the sealing process using the sealing substrate 15. For example, as shown in FIGS. 1 and 2, in the display device 100, foreign matter P is mixed in the window 20a, and the first electrode layer 21 and the second electrode layer 22 are short-circuited, or the possibility of short-circuiting is high. Suppose you are in a state. In such a short state, the organic layer 23 does not emit light in the entire pixel.

  Therefore, a repair device (not shown) irradiates the laser along the alternate long and short dash line S as shown in FIG. An alternate long and short dash line S is a line along the frame region 20 b of the window layer 20. That is, the repair device replaces the portion (first region) of the first electrode layer 21 below the organic layer 23 in the window (first window) in which the foreign matter P is mixed among the four windows 20a. The first electrode layer 21 is irradiated with a laser so as to be separated from other portions (second regions) to insulate them.

  The other part of the first electrode layer 21 is the first electrode layer 21 below the organic layer 23 provided in a window (second window (group)) different from the window 20a mixed with the foreign matter P. Part.

  In the present embodiment, of the driving substrate 10 and the sealing substrate 15, a method of irradiating laser from the sealing substrate 15 side (hereinafter referred to as “top side irradiation”) and a method of irradiating laser from the driving substrate 10 side ( Hereinafter, there are two methods (bottom side irradiation).

  When top side irradiation is selected, the repair device lasers the first electrode layer 21 via the sealing substrate 15, the color filter 17, the sealing resin layer 14, the organic layer 23, and the frame region 20 b of the window layer 20. Irradiate. The frame region 20b of the sealing substrate 15, the color filter 17, the sealing resin layer 14, the organic layer 23, and the window layer 20 is made of a material that transmits a laser having a specific wavelength region, as will be described later. The first electrode layer 21 absorbs the laser in the specific wavelength region. Thereby, as shown in FIG. 4, the 1st electrode layer 21 is parted and the parting trace (space) K is formed.

  When bottom side irradiation is selected, the repair device irradiates the first electrode layer 21 with laser through the substrate 11, the TFT layer 12, and the planarization layer 13. The substrate 11, the TFT layer 12, and the planarizing layer 13 are made of a material that transmits a laser having a specific wavelength region, as will be described later. The first electrode layer 21 absorbs the laser in the specific wavelength region. Thereby, the 1st electrode layer 21 is parted similarly to the case of the said top side irradiation, and the parting trace (space) K is formed.

  By such repair processing, the region of the first electrode layer 21 corresponding only to the window in which the foreign matter P is mixed among the four windows 20a is insulated from the region of the first electrode corresponding to the remaining three windows 20a. The Therefore, the function of the first electrode layer 21 corresponding to these three windows 20a is kept normal. As a result, the light emitting function of the organic layer 23 corresponding to these three windows 20a is left.

  By dividing the first electrode layer 21, a plurality of conductive parts (first conductive part and second conductive part) are formed. That is, one conductive part (first conductive part) is a conductive part corresponding to three windows 20a without foreign matter P, and the other conductive part (second conductive part) is a window in which foreign matter P is mixed. This is a conductive portion corresponding to 20a.

  As described above, according to the present technology, the first electrode layer 21 can be divided without dividing the second electrode layer as in Patent Document 1, and a new repair process can be provided. The repair process improves the production yield.

  In particular, according to the present embodiment, the repair process can be performed after the step of arranging the sealing substrate 15. Therefore, the production efficiency of the display device 100 can be increased as compared with the case where repair by laser irradiation is performed before the sealing material 16 placement step.

  Specifically, since the formation process from the TFT layer 12 to the sealing substrate 15 is often performed in a vacuum, the number of movements of the device to be processed between the vacuum and the atmospheric pressure is reduced as much as possible. Want to. This is because if the number of times of movement is large, the production efficiency is poor and the energy and cost for creating a vacuum environment increase.

  For example, if a repair process for eliminating a short defect due to the foreign matter P is performed during the manufacture of the display device 100, the number of times the device to be processed moves between vacuum and atmospheric pressure increases. For example, after forming all the layers up to the middle layer (for example, the organic layer 23 or the sealing resin layer 14), the repair process is performed, and then the device to be processed is returned to the vacuum again to return the color filter layer 19 and the sealing substrate. 15 is formed, the number of movements of the substrate 11 between vacuum and atmospheric pressure increases.

  Assuming that the repair process using the laser is performed in the atmospheric pressure, the repair process after the sealing substrate 15 is sealed reduces the number of times the substrate 11 moves between the vacuum and the atmospheric pressure of the device to be processed. be able to. Thereby, the production efficiency of the display apparatus 100 can be improved.

  Further, in particular, according to the repair process by the top side irradiation, the first electrode layer 21 is irradiated with laser from the sealing material 16 side through the window layer 20 (the frame region 20b thereof). It is possible to suppress the occurrence of 21 “blowing”.

  FIG. 5A is a photomicrograph showing the appearance of the “blown up” of the first electrode layer. FIG. 5B is an enlarged photograph of a portion surrounded by a broken line E in FIG. 5A.

  The device shown in FIG. 5A includes a glass substrate 111, a first electrode layer 121 of ALNd, an organic layer 123, and a second electrode layer (in this experiment, a Pt protective layer) 122. When the first electrode layer 121 is divided by being irradiated with a laser without the window layer 20 as in the present technology, a cavity K ′ is generated. Around the cavity K ′, the first electrode layer 121 is blown off beyond the organic layer 123, and a part of the blown off reaches the second electrode layer 122 that is an upper layer of the organic layer 123. This state is a state where a short circuit occurs or is highly likely to occur. The occurrence rate of this blow-up is also caused by the output of the laser.

  On the other hand, FIG. 6A is a photomicrograph showing a state in which the first electrode layer 121 is divided by being irradiated with a laser through the material of the window layer 120 in the state where the window layer 120 is present as in the present technology. 6B is an enlarged photograph of a portion surrounded by a broken line E in FIG. 6A. As described above, in the present technology, the first electrode layer 121 is neatly divided without generating blow-up. The first electrode layer 121 shows a parting trace 121b. That is, the short defect of the first electrode layer 21 and the second electrode layer 22 in FIGS. 2 and 4 can be surely removed.

  [Second Embodiment]

  FIG. 7 is a plan view showing one pixel of the display device according to the second embodiment of the present technology. 8 is a cross-sectional view taken along line CC in FIG. In the following description, the same members, functions, etc. included in the display device 100 according to the first embodiment will be simplified or omitted, and different points will be mainly described.

  Similar to the display device 100 according to the above-described embodiment, the display device 200 according to the present embodiment includes the window layer 40 having a plurality of windows 40a in one pixel. The window layer 40 has two rectangular windows 40a in one pixel.

  The first electrode layer 41 of the display device 200 has a plurality of conductive portions 41b provided independently of each other corresponding to the plurality of windows 40a, and a line portion 41c that conducts the conductive portions 41b. The line portion 41c is connected to a contact plug (not shown) provided in the planarization layer 13 through a contact hole 41a (see FIG. 7).

  As shown in FIG. 8, the arrangement of each layer in the stacking direction is the same as that of the display device 100 according to the first embodiment.

  As shown in FIG. 7, it is assumed that, for example, a foreign substance P is mixed in one window 40a and the first electrode layer 41 and the second electrode layer 22 are short-circuited (see FIG. 2). In this case, the repair device divides the line portion 41c by irradiating the line portion 41c along the alternate long and short dash line S, that is, across the longitudinal direction of the line portion 41c. Thereby, the conductive portions 41b of the first electrode layer 41 are insulated from each other.

  9 is a cross-sectional view showing a state in which the line portion 41c is divided, and FIG. 10 is a perspective view showing the line portion 41c having the division mark K. As shown in FIG. 9, either top side irradiation or bottom side irradiation may be used.

  In this embodiment, since the line part 41c is divided so that the longitudinal direction of the line part 41c which connects the electroconductive parts 41b may be crossed, the distance of laser irradiation can be decreased. As a result, insulation by laser irradiation can be facilitated and ensured, and the repair processing time by laser irradiation can be shortened.

  11A to 11D are plan views showing other forms of the window shape of the window layer. The first electrode layers of these display devices shown in FIGS. 11A to 11D are provided for each pixel, and these display devices are classified into the display device types according to the first embodiment. .

  The window layer 60 shown in FIG. 11A has three windows 60a in the vertical direction and two windows 60a in the horizontal direction.

  The window layer 65 shown in FIG. 11B has three horizontally long windows 65a in the vertical direction.

  The window layer 70 shown in FIG. 11C has four windows 70a that are triangular in the vertical direction. The directions of the triangles are such that the triangles are arranged as densely as possible.

  The window layer 75 shown in FIG. 11D has two vertically long windows 75a in the horizontal direction.

  Note that the window layer having the window shape shown in FIGS. 11A to 11D is applied to a display device in which a plurality of conductive portions are provided for each pixel like the display device 200 according to the second embodiment. Also good.
