[0044] The inventive concept will now be described more fully below with reference to the accompanying drawings in which embodiments are shown. However, the inventive concept can be implemented in different forms and should not be construed as being limited to the embodiments set forth herein. On the contrary, these embodiments are provided so that the disclosure will be thorough and complete, and will fully convey the scope of the inventive concept to those skilled in the art.

[0045] It will also be understood that when a layer is referred to as being "on" another layer or substrate, it can be directly on the other layer or substrate, or intervening layers may also be present. Like reference numerals refer to like components throughout the specification. In the drawings, the thickness of layers and regions are exaggerated for clarity.

[0046] Although the terms "first", "second", etc. can be used in this article to describe various elements, these elements should not be limited by these terms. These terms can be used to distinguish an element from another element. Therefore, the first element discussed below can be referred to as the second element without departing from the teaching of one or more embodiments. Describing an element as a "first" element may not require or imply the existence of a second element or other elements. The terms "first", "second", etc. can also be used in this article to distinguish the categories or groups of different elements. For the sake of simplicity, the terms "first", "second", etc. can respectively represent "first category (or first group)", "second category (or second group)", etc.

[0047] The features of the various embodiments of the present disclosure may be combined in part or in whole. As will be clearly understood by those skilled in the art, various interactions and operations are technically possible. The various embodiments may be practiced individually or in combination.

[0048] Hereinafter, embodiments will be described in detail with reference to the accompanying drawings.

[0049] Figure 1 is a plan view of a display device according to an embodiment. Figure 2 It is along Figure 1 A cross-sectional view taken along line II'. Figure 3 It is along Figure 1 A cross-sectional view taken along line II-II'.

[0050] like Figures 1 to 3As illustrated in , the display device according to the embodiment may include a display panel 100, a passivation layer 200, a polarizing plate POL, an adhesive layer 300, a hole cover 500, light blocking layers 401 and 402, and a window WD.

[0051] The display panel 100 may include a substrate SUB, a light emitting element layer EMTL, and an encapsulation layer ENC. Meanwhile, although not shown, the display panel 100 may further include a transistor layer disposed between the substrate SUB and the light emitting element layer EMTL, a touch sensing unit disposed on the encapsulation layer ENC, and a color filter layer disposed on the touch sensing unit.

[0052] The passivation layer 200 may be disposed under the display panel 100. For example, the passivation layer 200 may be disposed under the substrate SUB. In other words, the passivation layer 200 may be disposed on the lower side of the polarizing plate POL, and the display panel 100 is interposed therebetween. The passivation layer 200 may prevent external light from reaching the display panel 100. In addition, the passivation layer 200 may prevent external impact from being transmitted to the bottom of the display panel 100. The passivation layer 200 may have a film form.

[0053] The substrate SUB may be disposed on the passivation layer 200. The substrate SUB may be a base substrate or a base member. The substrate SUB may be a flexible substrate that can be bent, folded, or curled. For example, the substrate SUB may include, but is not limited to, a polymer resin such as polyimide (PI). For another example, the substrate SUB may include a glass material or a metal material.

[0054] The transistor layer may be disposed on the substrate SUB. The transistor layer may include a plurality of thin film transistors forming a pixel circuit of a pixel. The transistor layer may include a gate line, a data line, a voltage line, a gate control line, a fan-out line for connecting a display driver to a data line, a lead for connecting a display driver to a pad, etc. Each of the thin film transistors may include a semiconductor region, a source electrode, a drain electrode, and a gate electrode. For example, when a gate driver is formed on one side of a non-display area of ​​the display panel 100, the gate driver may include a thin film transistor.

[0055] The transistor layer may be arranged in a display area, a non-display area, and a sub-area. The thin film transistor, gate line, data line, and voltage line in each of the pixels in the transistor layer may be arranged in the display area. The gate control line and fan-out line in the transistor layer may be arranged in the non-display area. The lead line of the transistor layer may be arranged in the sub-area.

[0056] The light emitting element layer EMTL may be disposed on the transistor layer. The light emitting element layer EMTL may include a plurality of light emitting elements and a pixel defining film for defining pixels, in each of the plurality of light emitting elements, a pixel electrode, a light emitting layer, and a common electrode are sequentially stacked on each other to emit light. The plurality of light emitting elements in the light emitting element layer EMTL may be disposed in a display area.

[0057] For example, the light-emitting layer may be an organic light-emitting layer including an organic material. The light-emitting layer may include a hole transport layer, an organic light-emitting layer, and an electron transport layer. When the pixel electrode receives a predetermined voltage through a thin film transistor in the transistor layer and the common electrode receives a cathode voltage, holes and electrons may move to the organic light-emitting layer through the hole transport layer and the electron transport layer, respectively, so that they recombine in the organic light-emitting layer to emit light. For example, the pixel electrode may be an anode electrode, and the common electrode may be a cathode electrode. However, it should be understood that the present disclosure is not limited thereto.

[0058] As another example, the light emitting elements may include micro light emitting diodes, quantum dot light emitting diodes each including a quantum dot light emitting layer, or inorganic light emitting diodes each including an inorganic semiconductor.

[0059] The encapsulation layer ENC may cover the upper surface and the side surface of the light emitting element layer EMTL and may protect the light emitting element layer EMTL. The encapsulation layer ENC may include at least one inorganic layer and at least one organic layer for encapsulating the light emitting element layer EMTL.

[0060] The touch sensing unit may be disposed on the encapsulation layer ENC. The touch sensing unit may include a plurality of touch electrodes for sensing a user's touch through capacitive sensing and a touch line connecting the plurality of touch electrodes to a touch driver. For example, the touch sensing unit may sense a user's touch through mutual capacitance sensing or self capacitance sensing.

[0061] For another example, the touch sensing unit may be provided on a separate substrate provided on the display unit. In this case, the substrate supporting the touch sensing unit may be a base member encapsulating the display unit.

[0062] A plurality of touch electrodes of the touch sensing unit may be disposed in a touch sensor region overlapping the display region. A touch line of the touch sensing unit may be disposed in a touch peripheral region overlapping the non-display region.

[0063] The color filter layer may be disposed on the touch sensing unit. The color filter layer may include a plurality of color filters respectively associated with a plurality of emission regions. Each of the color filters may selectively transmit light of a specific wavelength and block or absorb light of other wavelengths. The color filter layer may absorb some of the light introduced from outside the display device to reduce reflection of external light. Accordingly, the color filter layer may prevent distortion of color due to reflection of external light.

[0064] Since the color filter layer is directly disposed on the touch sensing unit, the display device may not require a separate substrate for the color filter layer, and thus the thickness of the display device can be relatively reduced.

[0065] like Figure 2 As illustrated in , the polarizing plate POL may be disposed on the encapsulation layer ENC. For example, the polarizing plate POL may be disposed on the color filter layer of the display panel 100. The polarizing plate POL may include a linear polarizing layer and at least one phase delay layer. The linear polarizing layer may be an optical layer that linearly polarizes light provided from the outside in one direction. The phase delay layer may be a λ / 2 phase delay layer or a λ / 4 phase delay layer. The polarizing plate POL can play a role in reducing reflection caused by external light.

[0066] like Figures 1 to 3 As shown in FIG. 1 , the polarizing plate POL may have a through hole 777 passing therethrough in the third direction DR3. At this time, one side of the through hole 777 may have an open shape. For example, Figure 1 As shown in FIG. 1 , one side of the through hole 777 may have a shape open in the second direction DR2. Figure 1 From the plane view illustrated in FIG. 1 (e.g., a plane defined by the first direction DR1 and the second direction DR2), the through hole 777 may have a U shape. However, the shape of the through hole 777 of the polarizing plate POL is not limited thereto. For example, from a plane view, the through hole 777 of the polarizing plate POL may have a closed curve shape such as a ring. In an embodiment, the display panel 100 as described above may have a through hole 888 disposed below the through hole 777 of the polarizing plate POL and disposed to correspond to the through hole 777 of the polarizing plate POL. In addition, the passivation layer 200 described above may have a through hole 999 disposed below the through hole 777 of the polarizing plate POL and disposed to correspond to the through hole 777 of the polarizing plate POL.

[0067] The adhesive layer 300 may be disposed on the polarizing plate POL. The adhesive layer 300 may be, for example, an optically transparent adhesive layer.

[0068] The hole cover 500 may be disposed on the adhesive layer 300 and the polarizing plate POL. The hole cover 500 may be attached to the polarizing plate POL using the adhesive layer 300. At this time, the hole cover 500 may be disposed on the adhesive layer 300 and the polarizing plate POL to cover the through hole 777 of the polarizing plate POL. For example, the hole cover 500 may be disposed between the window WD and the through hole 777 of the polarizing plate POL. In an embodiment, as shown in FIG. Figure 1 and Figure 3 As shown in the figure, the hole cover 500 may have an area larger than the area of ​​the through hole 777 so as to completely cover the through hole 777. The hole cover 500 may be made of a transparent material. For example, the hole cover 500 may include at least one material selected from transparent glass, transparent acrylic, transparent urethane, and transparent polymethyl methacrylate (PMMA). In an embodiment, the hole cover 500 may have a light transmittance of, for example, 90% or more. The hole cover 500 may prevent the resin, which is the material of the window WD, from flowing through the through hole 777 of the polarizing plate POL during the attachment process of the window WD. In addition, since the hole cover 500 is made of a transparent material, light can normally enter the camera module 600 disposed under the hole cover 500. In an embodiment, the hole cover 500 and the adhesive layer 300 may be attached to each other to form a component (e.g., a hole cover member). In other words, the hole cover 500 and the adhesive layer 300 may be attached to each other and provided as a single component (e.g., a hole cover member). For example, the hole cover member may include the hole cover 500 and the adhesive layer 300 .

[0069] The light blocking layers 401 and 402 may include a first light blocking layer 401 and a second light blocking layer 402. In an embodiment, the first light blocking layer 401 and the second light blocking layer 402 may be integrally formed.

[0070] The first light blocking layer 401 may be disposed on the hole cover 500. The first light blocking layer 401 may be disposed on the edge of the hole cover 500. The first light blocking layer 401 may have an opening 415 defining a transmission area 515 of the hole cover 500. The transmission area 515 of the hole cover 500 may be arranged above the camera module 600 and corresponding to the camera module 600. In other words, the opening 415 of the first light blocking layer 401 and the transmission area 515 of the hole cover 500 may be arranged above the lens of the camera module 600 and overlap with the lens of the camera module 600. In addition, the first light blocking layer 401 may be disposed on the side of the hole cover 500 and the side of the adhesive layer 300. In other words, at least a portion of the light blocking layers 401 and 402 may be disposed between the hole cover 500 and the window WD. The first light blocking layer 401 may be formed on the hole cover 500 using a printing method. The first light blocking layer 401 may be a printed layer containing a pigment or a dye. The first light blocking layer 401 may have a black color. However, the present disclosure is not limited thereto, and the first light blocking layer 401 includes a material that blocks light and its color is not limited to black. In an embodiment, the adhesive layer 300, the hole cover 500, and the first light blocking layer 401 may be attached to each other to form a component (e.g., a hole cover member). In other words, the adhesive layer 300, the hole cover 500, and the first light blocking layer 401 may be attached to each other and provided as a single component (e.g., a hole cover member). For example, the hole cover member may include the hole cover 500, the adhesive layer 300, and the first light blocking layer 401.

[0071] The transmission area 515 of the hole cover 500 and the opening 415 of the first light blocking layer 401 may be disposed above the through hole 777 of the polarizing plate POL and correspond to the through hole 777 of the polarizing plate POL. In other words, the transmission area 515 of the hole cover 500 and the opening 415 of the first light blocking layer 401 may be above the through hole 777 of the polarizing plate POL and overlap with the through hole 777 of the polarizing plate POL.

[0072] The second light blocking layer 402 may be disposed on the edge of the polarizing plate POL. For example, the second light blocking layer 402 may be disposed along the edge of the polarizing plate POL. The second light blocking layer 402 may be formed on the polarizing plate POL using a printing method. The second light blocking layer 402 may be made of the same material as the first light blocking layer 401 described above.

[0073] The window WD may be disposed on the polarizing plate POL, the hole cover 500, the first light blocking layer 401, and the second light blocking layer 402. The window WD may be made of transparent glass or transparent resin.

[0074] The camera module 600 may be disposed under the passivation layer 200. For example, the camera module 600 may be disposed to correspond to the through hole 999 of the passivation layer 200. The camera module 600 may receive light from the outside through the through hole 999 of the passivation layer 200, the through hole 888 of the display panel 100, and the through hole 777 of the polarizing plate POL.

[0075] Figures 4 to 11 is a view illustrating a method of manufacturing a display device according to an embodiment. Figure 5 It is along Figure 4 A cross-sectional view taken along line II-II', Figure 7 It is along Figure 6 A cross-sectional view taken along line II-II', Fig. 9 It is along Figure 8 A cross-sectional view taken along line II-II', and Fig.11 It is along Fig.10 A cross-sectional view taken along line II-II'.

[0076] First, if Figure 4 and Figure 5 As illustrated in FIG. 1 , a passivation layer 200 may be provided on the lower surface of the display panel 100, and a polarizing plate POL may be provided on the upper surface of the display panel 100. For example, the passivation layer 200 is provided on the lower surface of the substrate SUB provided in the display panel 100, and the polarizing plate POL is provided on the encapsulation layer ENC provided in the display panel 100. Meanwhile, when the above-mentioned touch sensing unit and the color filter layer are further provided on the encapsulation layer ENC, the above-mentioned polarizing plate POL may be provided on the color filter layer.

[0077] Then, if Figure 6 and Figure 7 As illustrated in , after the adhesive layer 300 is provided on the polarizing plate POL, the hole cover 500 may be provided on the adhesive layer 300. At this time, the hole cover 500 may be placed on the polarizing plate POL so as to completely cover the through hole 777 of the polarizing plate POL. In an embodiment, the adhesive layer 300 may be provided in a state of being attached (or adhered) to the lower surface of the hole cover 500. In other words, one surface of the adhesive layer 300 may be provided in a state of being attached to the lower surface of the hole cover 500. The other surface of the adhesive layer 300 may be attached to the polarizing plate POL.

[0078] Afterwards, if Figure 8 and Fig. 9 As shown in FIG. 5 , light blocking layers 401 and 402 may be disposed on the hole cover 500 and the polarizing plate POL. For example, a first light blocking layer 401 defining a transmission region 515 of the hole cover 500 is disposed on the hole cover 500, and a second light blocking layer 402 may be disposed on the polarizing plate POL along an edge of the polarizing plate POL.

[0079] Next, if Fig.10 and Fig.11 As shown in the figure, a window WD may be provided on the hole cover 500, the polarizing plate POL, the first light blocking layer 401, and the second light blocking layer 402. For example, after a resin for manufacturing the window WD is applied to the hole cover 500, the polarizing plate POL, the first light blocking layer 401, and the second light blocking layer 402, when light is irradiated onto the applied resin, the resin may be cured, thereby forming the window WD. At this time, since the through hole 777 of the polarizing plate POL may be covered by the hole cover 500, the resin applied on the polarizing plate POL may be prevented from flowing to the outside through the through hole 777. In addition, since the hole cover 500 is made of a transparent material, light incident on the camera module 600 placed thereunder may pass through normally.

[0080] Fig.12 and Fig.13 is a view illustrating a method of manufacturing a display device according to an embodiment. Fig.13 It is along Fig.12 A cross-sectional view taken along line III-III'.

[0081] In the following, we will base on Figure 4 , Figure 5 , Fig.12 , Fig.13 , Figure 8 , Fig. 9 , Fig.10 and Fig.11 A method of manufacturing a display device according to an embodiment is described.

Figure 4 and Figure 5 And the above-mentioned related description gives its detailed description.

[0083] Next, if Fig.12 and Fig.13 As shown in FIG. 1 , an adhesive layer 300, a hole cover 500, and a first light blocking layer 401 may be provided on the polarizing plate POL. For example, the adhesive layer 300, the hole cover 500, and the first light blocking layer 401 may be attached to each other to form one component (e.g., a hole cover member). In other words, the adhesive layer 300, the hole cover 500, and the first light blocking layer 401 may be attached to each other and provided as a single component (e.g., a hole cover member). For example, the hole cover member may include the hole cover 500, the adhesive layer 300, and the first light blocking layer 401.

[0084] Then, as mentioned above Figure 8 and Fig. 9 As shown in FIG. 4 , a second light blocking layer 402 may be disposed on the polarizing plate POL along the edge of the polarizing plate POL. Figure 8 and Fig. 9 And the above-mentioned related description gives its detailed description.

[0085] Afterwards, as mentioned above Fig.10 and Fig.11 As shown in FIG. 5 , a window WD may be provided on the hole cover 500, the polarizing plate POL, the first light blocking layer 401, and the second light blocking layer 402. At least a portion of the first light blocking layer 401 may be provided between the hole cover 500 and the window WD. Fig.10 and Fig.11 And the above-mentioned related description gives its detailed description.

[0086] It will be understood by those skilled in the art that the present disclosure can be implemented in other specific forms without changing the technical spirit or essential features of the present disclosure.
