Technical Field

[0001] The disclosure relates to a display device, and more particularly to a display device capable of adjusting a viewing angle. Background Art

[0002] Flat panel displays are used as display devices to replace cathode ray tube displays due to their characteristics such as light weight and thinness. A representative example of such flat panel display devices is an organic light emitting display device.

[0003] Display devices are typically manufactured to have a wide viewing angle, but it may be necessary to temporarily implement a narrow viewing angle so that no one except the user can see the screen. Utility Model Content

[0004] The embodiment provides a display device having excellent lifespan characteristics and an adjustable viewing angle.

[0005] The display device according to the embodiment includes: a substrate including unit pixel areas repeatedly arranged in a plan view; a first light emitting device, a second light emitting device, and a third light emitting device, which are arranged in each of the unit pixel areas on the substrate and emit light of different colors; a pixel defining layer, which defines a first pixel opening, a second pixel opening, and a third pixel opening, the first pixel opening being located above a first pixel electrode of the first light emitting device, the second pixel opening being located above a second pixel electrode of the second light emitting device, and the third pixel opening being located above a third electrode of the third light emitting device; and a separation pattern, which is arranged on the first light emitting device, the second light emitting device, and the third light emitting device, and partially covers the first pixel opening, the second pixel opening, and the third pixel opening, and in a plan view, the first overlap ratio, the second overlap ratio, and the third overlap ratio are equal to each other.

[0007] In an embodiment, the display device may further include fourth, fifth and sixth light emitting devices disposed in each of the unit pixel regions and emitting light of different colors, and the partition pattern may be spaced apart from the fourth, fifth and sixth light emitting devices in a plan view.

[0008] In an embodiment, in a wide viewing angle mode, the first light emitting device, the second light emitting device, and the third light emitting device may be configured to selectively emit light, and the fourth light emitting device, the fifth light emitting device, and the sixth light emitting device may be configured to emit light. In a narrow viewing angle mode, the first light emitting device, the second light emitting device, and the third light emitting device may be configured to emit light, and the light emission of the fourth light emitting device, the fifth light emitting device, and the sixth light emitting device may be configured to remain off.

[0009] In an embodiment, the pixel defining layer may further define a fourth pixel opening, a fifth pixel opening and a sixth pixel opening, the fourth pixel opening being located above a fourth pixel electrode of a fourth light-emitting device, the fifth pixel opening being located above a fifth pixel electrode of a fifth light-emitting device, and the sixth pixel opening being located above a sixth pixel electrode of a sixth light-emitting device.

[0010] In an embodiment, the first light emitting device and the fourth light emitting device may emit light of the same color, the second light emitting device and the fifth light emitting device may emit light of the same color, and the third light emitting device and the sixth light emitting device may emit light of the same color.

[0011] In an embodiment, in a plan view, a total area of ​​the first pixel openings and a total area of ​​the fourth pixel openings may be different from each other.

[0012] In an embodiment, in a plan view, a total area of ​​the first pixel openings may be greater than a total area of ​​the fourth pixel openings.

[0013] In an embodiment, in a plan view, a total area of ​​the second pixel opening and a total area of ​​the fifth pixel opening may be equal to each other, and a total area of ​​the third pixel opening and a total area of ​​the sixth pixel opening may be equal to each other.

[0015] In an embodiment, in a plan view, a total area of ​​the second pixel opening and a total area of ​​the fifth pixel opening may be different from each other, and a total area of ​​the third pixel opening and a total area of ​​the sixth pixel opening may be different from each other.

[0016] In an embodiment, the separation pattern may include at least one of a black pigment, a black dye, and molybdenum tantalum oxide (MTO).

[0017] In an embodiment, the display device may further include a light transmitting layer disposed between the partition patterns.

[0018] In an embodiment, each of the separation patterns may extend in a first direction and be spaced apart from each other along a second direction crossing the first direction.

[0019] The display device according to the embodiment includes: a substrate including unit pixel areas repeatedly arranged in a plan view; a light emitting device disposed in each of the unit pixel areas on the substrate and emitting light of different colors; a pixel defining layer defining pixel openings, each of the pixel openings being located above a pixel electrode of each of the light emitting devices; and a separation pattern disposed on the light emitting device and partially covering the pixel openings in a plan view, wherein the pixel openings have the same overlap ratio. The overlap ratio is a ratio of an area of ​​the pixel openings covered by the separation pattern to a total area of ​​the pixel openings.

[0020] In an embodiment, the pixel openings may have the same aperture ratio. The aperture ratio may be a ratio of an area of ​​a portion of the pixel opening adjacent to a portion covered by the partition pattern to a total area of ​​the pixel opening.

[0021] In an embodiment, the light emitting device may be configured to selectively emit light in a wide viewing angle mode, and the light emitting device may be configured to emit light in a narrow viewing angle mode.

[0022] In an embodiment, the separation pattern may include at least one of a black pigment, a black dye, and molybdenum tantalum oxide (MTO).

[0023] In an embodiment, the display device may further include a light transmitting layer disposed between the partition patterns.

[0024] In an embodiment, each of the separation patterns may extend in a first direction and be spaced apart from each other along a second direction crossing the first direction.

[0025] In the display device according to some embodiments, the display device may include a separation pattern disposed on the light emitting device to be driven in a wide viewing angle mode and a narrow viewing angle mode, respectively.

[0026] In addition, the display device may have a structure in which the total area of ​​each of the pixel openings defined in each of the unit pixel regions and corresponding to the light emitting devices emitting light of the same color is different. Therefore, the pixel openings overlapped with the partition pattern may all have the same effective aperture ratio.

[0027] That is, even when the display device includes a partition pattern for adjusting the viewing angle, according to the planar shape of each of the pixel openings and / or the color of the light emitted by the corresponding light-emitting device, no deviation in the effective aperture ratio occurs between the pixel openings overlapping the partition pattern. Therefore, the luminous efficiency of the light-emitting devices overlapping the partition pattern can be substantially the same. Therefore, the life characteristics of the light-emitting devices overlapping the partition pattern can be improved.

[0050] The display device 1 (eg, substrate SUB) may include a unit pixel area UPXA disposed in the display area DA. For example, the unit pixel area UPXA may be repeatedly arranged along the first direction DR1 and the second direction DR2. At this time, each of the unit pixel areas UPXA is a division of a repeated shape and does not represent a disconnection in the structure.

[0051] At least two or more pixels PX may be provided in each of the unit pixel regions UPXA. In other words, at least two or more light emitting devices may be provided in each of the unit pixel regions UPXA. Therefore, each of the unit pixel regions UPXA may emit light of a color obtained by combining the light emitted by the light emitting devices. The arrangement of the pixels PX in each of the unit pixel regions UPXA may be the same for each unit pixel region UPXA.

[0052] In an embodiment, two light emitting devices emitting light of a first color, two light emitting devices emitting light of a second color, and two light emitting devices emitting light of a third color may be disposed in each of the unit pixel areas UPXA.

For example, Figure 3 is a schematic diagram showing a Figure 2 A plan view of an arrangement of pixel electrodes and pixel defining layers of a display device, and Figure 4 is a schematic diagram showing a Figure 2 A plan view of an arrangement of light emitting devices and separation patterns of a display device.

[0055] Figure 5 It is along Figure 4 For example, Figure 5 Shown with Figure 4 The light emitting area EA corresponding to the third light emitting device LED3. Figure 4 The cross-sectional structure of the first light emitting device LED1, the cross-sectional structure of the second light emitting device LED2, the cross-sectional structure of the fourth light emitting device LED4, the cross-sectional structure of the fifth light emitting device LED5 and the cross-sectional structure of the sixth light emitting device LED6 can be the same as Figure 5 The cross-sectional structure of the third light emitting device LED3 shown in FIG. 1 is substantially the same.

Each of the first to sixth light emitting devices LED1, LED2, LED3, LED4, LED5, and LED6 may include a pixel electrode, a light emitting layer EL, and a common electrode CE.

[0057] The substrate SUB may include a transparent material or an opaque material. In an embodiment, examples of materials that may be used as the substrate SUB may include glass, quartz, plastic, etc. These may be used alone or in combination with each other.

[0058] The buffer layer BFR may be disposed on the substrate SUB. The buffer layer BFR may prevent impurities such as oxygen and moisture from diffusing into an upper portion of the substrate SUB. The buffer layer BFR may include an inorganic insulating material such as a silicon compound or a metal oxide.

[0060] In an embodiment, the first insulating layer IL1 may be disposed on the buffer layer BFR. The first insulating layer IL1 may cover the active pattern ACT. In an embodiment, the first insulating layer IL1 may be arranged on the active pattern ACT in a pattern so that a portion of the active pattern ACT is exposed. For example, the first insulating layer IL1 may be arranged on the active pattern ACT in a pattern so as to overlap with the first conductive pattern CP1. The first insulating layer IL1 may include an inorganic insulating material.

[0061] The first conductive pattern CP1 may be disposed on the first insulating layer IL1. In an embodiment, the first conductive pattern CP1 may include a metal, an alloy, a conductive metal oxide, a transparent conductive material, or the like.

[0062] The second insulating layer IL2 may be disposed on the first insulating layer IL1. In an embodiment, the second insulating layer IL2 may cover the first conductive pattern CP1. The second insulating layer IL2 may include an inorganic insulating material.

[0063] The second conductive pattern CP2 and the third conductive pattern CP3 may be disposed on the second insulating layer IL2.

[0065] at the same time, Figure 5 The configuration, arrangement, and connection structure of the transistor TR and the plurality of insulating layers IL1 , IL2 , and IL3 shown in FIG. 1 are merely examples and may be changed in various ways.

[0066] Further references Figure 3 , the pixel electrodes PE1, PE2, PE3, PE4, PE5 and PE6 may be disposed on the third insulating layer IL3. Each of the pixel electrodes PE1, PE2, PE3, PE4, PE5 and PE6 may be electrically connected to the transistor TR through a contact hole formed in the third insulating layer IL3. In an embodiment, the pixel electrodes PE1, PE2, PE3, PE4, PE5 and PE6 may include metal, alloy, conductive metal oxide, transparent conductive material, etc.

[0067] Pixel electrodes PE1, PE2, PE3, PE4, PE5, and PE6 may be disposed on the third insulating layer IL3 in each of the unit pixel areas UPXA. The pixel electrodes PE1, PE2, PE3, PE4, PE5, and PE6 may be arranged to be spaced apart from each other.

[0068] The pixel defining layer PDL may be disposed on the third insulating layer IL3 and the pixel electrodes PE1, PE2, PE3, PE4, PE5, and PE6. The pixel defining layer PDL may include an organic insulating material. In an embodiment, the pixel defining layer PDL may further include a light shielding material. Examples of the light shielding material of the pixel defining layer PDL may include black pigment, black dye, and the like.

[0069] The pixel defining layer PDL may cover an edge of each of the pixel electrodes PE1, PE2, PE3, PE4, PE5, and PE6 in each of the unit pixel areas UPXA and expose a portion of each of the pixel electrodes PE1, PE2, PE3, PE4, PE5, and PE6.

[0070] Specifically, the pixel defining layer PDL may define a first pixel opening PO1 exposing a portion of the first pixel electrode PE1, a second pixel opening PO2 exposing a portion of the second pixel electrode PE2, a third pixel opening PO3 exposing a portion of the third pixel electrode PE3, a fourth pixel opening PO4 exposing a portion of the fourth pixel electrode PE4, a fifth pixel opening PO5 exposing a portion of the fifth pixel electrode PE5, and a sixth pixel opening PO6 exposing a portion of the sixth pixel electrode PE6.

[0071] In an embodiment, the arrangement structure of the first to sixth pixel openings PO1, PO2, PO3, PO4, PO5 and PO6 defined in each of the unit pixel areas UPXA may be an S-stripe structure. For example, the first pixel opening PO1 and the second pixel opening PO2 may be arranged in the first column, the fourth pixel opening PO4 and the fifth pixel opening PO5 may be arranged in the second column adjacent to the first column, the third pixel opening PO3 may be arranged in the third column adjacent to the second column, and the sixth pixel opening PO6 may be arranged in the fourth column adjacent to the third column.

[0072] That is, in a plan view, the first pixel opening PO1 and the fourth pixel opening PO4 may be arranged adjacent to each other so that their long sides face each other, the second pixel opening PO2 and the fifth pixel opening PO5 may be arranged adjacent to each other so that their long sides face each other, and the third pixel opening PO3 and the sixth pixel opening PO6 may be arranged adjacent to each other so that their long sides face each other. In addition, the long side of each of the fourth pixel opening PO4 and the fifth pixel opening PO5 may be arranged to face the long side of the third pixel opening PO3. However, the present disclosure is not necessarily limited to this, and the planar arrangement of the first to sixth pixel openings PO1, PO2, PO3, PO4, PO5, and PO6 may be variously changed according to the embodiment.

[0073] In an embodiment, in a plan view, a total area TA1 of the first pixel opening PO1 may be substantially equal to a total area TA4 of the fourth pixel opening PO4, and a total area TA2 of the second pixel opening PO2 may be substantially equal to a total area TA5 of the fifth pixel opening PO5. In other words, an opening ratio of the first pixel opening PO1 may be substantially equal to an opening ratio of the fourth pixel opening PO4, and an opening ratio of the second pixel opening PO2 may be substantially equal to an opening ratio of the fifth pixel opening PO5. However, the present disclosure is not necessarily limited thereto.

[0074] In an embodiment, the length of the long side of the first pixel opening PO1 and the length of the long side of the fourth pixel opening PO4 may be substantially the same, and the length of the short side of the first pixel opening PO1 and the length of the short side of the fourth pixel opening PO4 may be substantially the same. Therefore, the total area TA1 of the first pixel opening PO1 may be substantially equal to the total area TA4 of the fourth pixel opening PO4. However, the present disclosure is not necessarily limited thereto, and if the total area TA1 of the first pixel opening PO1 and the total area TA4 of the fourth pixel opening PO4 are the same, the planar shape of the first pixel opening PO1 and the planar shape of the fourth pixel opening PO4 may be changed in various ways.

[0075] In addition, the length of the long side of the second pixel opening PO2 and the length of the long side of the fifth pixel opening PO5 may be substantially the same, and the length of the short side of the second pixel opening PO2 and the length of the short side of the fifth pixel opening PO5 may be substantially the same. Therefore, the total area TA2 of the second pixel opening PO2 may be substantially equal to the total area TA5 of the fifth pixel opening PO5. However, the present disclosure is not necessarily limited thereto, and if the total area TA2 of the second pixel opening PO2 and the total area TA5 of the fifth pixel opening PO5 are the same, the planar shape of the second pixel opening PO2 and the planar shape of the fifth pixel opening PO5 may be changed in various ways.

[0076] In an embodiment, in a plan view, the total area TA3 of the third pixel opening PO3 and the total area TA6 of the sixth pixel opening PO6 may be different from each other. In other words, the opening ratio of the third pixel opening PO3 and the opening ratio of the sixth pixel opening PO6 may be different from each other.

[0077] For example, the total area TA3 of the third pixel opening PO3 may be greater than the total area TA6 of the sixth pixel opening PO6. In other words, the aperture ratio of the third pixel opening PO3 may be greater than the aperture ratio of the sixth pixel opening PO6.

[0078] In an embodiment, the long side of the third pixel opening PO3 may be defined as being longer than the long side of the sixth pixel opening PO6 in the first direction DR1. That is, the third pixel opening PO3 may be defined as being longer than the sixth pixel opening PO6 in the first direction DR1. In addition, the length of the short side of the third pixel opening PO3 and the length of the short side of the sixth pixel opening PO6 may be substantially the same. Therefore, the total area TA3 of the third pixel opening PO3 may be greater than the total area TA6 of the sixth pixel opening PO6. However, the present disclosure is not necessarily limited thereto, and if the total area TA3 of the third pixel opening PO3 is greater than the total area TA6 of the sixth pixel opening PO6, the planar shape of the third pixel opening PO3 and the planar shape of the sixth pixel opening PO6 may be changed in various ways.

[0079] The light emitting area EA may be defined by the first to sixth pixel openings PO1, PO2, PO3, PO4, PO5, and PO6 of the pixel defining layer PDL. That is, the pixel defining layer PDL may be disposed in the non-light emitting area NEA surrounding the light emitting area EA. In other words, the pixel defining layer PDL may have a grid shape in a plan view.

[0080] The light emitting layer EL may be disposed in the first to sixth pixel openings PO1 , PO2 , PO3 , PO4 , PO5 , and PO6 of the pixel defining layer PDL.

[0081] In an embodiment, the light emitting layer EL may include a material that emits light. For example, the light emitting layer EL may include an organic light emitting material. In an embodiment, the light emitting layer EL of the first light emitting device LED1 and the light emitting layer EL of the fourth light emitting device LED4 may include a material capable of emitting light of a first color, and the light emitting layer EL of the second light emitting device LED2 and the light emitting layer EL of the light emitting device LED5 may include a material capable of emitting light of a second color, and the light emitting layer EL of the third light emitting device LED3 and the light emitting layer EL of the sixth light emitting device LED6 may include a material capable of emitting light of a third color. For example, the first color may be red, the second color may be green, and the third color may be blue. However, the present disclosure is not necessarily limited thereto.

[0082] Meanwhile, a functional layer such as a hole injection layer, a hole transport layer, an electron transport layer, and an electron injection layer may be additionally provided above and / or below the light emitting layer EL.

[0083] The common electrode CE may be disposed on the light emitting layer EL. The common electrode CE may include a conductive material such as a metal, an alloy, a conductive metal nitride, a conductive metal oxide, or a transparent conductive material. In an embodiment, the common electrode CE may extend continuously across a plurality of pixels.

[0084] As a result, the first light-emitting device LED1 may include a first pixel electrode PE1, a light-emitting layer EL and a common electrode CE, the second light-emitting device LED2 may include a second pixel electrode PE2, a light-emitting layer EL and a common electrode CE, the third light-emitting device LED3 may include a third pixel electrode PE3, a light-emitting layer EL and a common electrode CE, the fourth light-emitting device LED4 may include a fourth pixel electrode PE4, a light-emitting layer EL and a common electrode CE, the fifth light-emitting device LED5 may include a fifth pixel electrode PE5, a light-emitting layer EL and a common electrode CE, and the sixth light-emitting device LED6 may include a sixth pixel electrode PE6, a light-emitting layer EL and a common electrode CE.

[0085] The first to third light emitting devices LED1 , LED2 , and LED3 may provide lights of different colors to the light emitting area EA, and the fourth to sixth light emitting devices LED4 , LED5 , and LED6 may provide lights of different colors to the light emitting area EA.

[0086] For example, the first light emitting device LED1 and the fourth light emitting device LED4 can provide light of a first color to the light emitting area EA, the second light emitting device LED2 and the fifth light emitting device LED5 can provide light of a second color to the light emitting area EA, and the third light emitting device LED3 and the sixth light emitting device LED6 can provide light of a third color to the light emitting area EA. As described above, the first color can be red, the second color can be green, and the third color can be blue. However, the present disclosure is not necessarily limited thereto.

[0087] In an embodiment, the display device 1 may be operated in a normal drive mode or a private drive mode. The normal drive mode may be a mode that provides a wide viewing angle in all directions. That is, the normal drive mode may be referred to as a wide viewing angle mode. The private drive mode may be a mode that provides a narrow viewing angle in a predetermined direction, and may be a mode in which the side view is of low quality or blocked compared to the normal drive mode. As used herein, a "side view" is a view of the display device 1 from an area that is not a main viewing area, which is typically in front of a central area of ​​the display device 1. The private drive mode may be referred to as a narrow viewing angle mode, in which the image on the display device 1 is clearly visible only from the main viewing area of ​​the display device 1. In the private drive mode, the side view of the display device 1 may not be clear or blocked.

[0088] When the controller 170 (see Figure 1 ) receives a selection signal indicating operation in the normal driving mode or the private driving mode, the controller 170 (see Figure 1 ) can be sent to the scan driver 130 (see Figure 1 ) and data driver 150 (see Figure 1 ) outputs a control signal so that the display device 1 operates in a normal driving mode or a private driving mode according to the selection signal.

[0089] In the private drive mode, the first to third light-emitting devices LED1, LED2, and LED3 arranged in each of the unit pixel areas UPXA can be selected by the scan signal and emit light with a brightness corresponding to the data signal. In the private drive mode, the light emission function of the fourth light-emitting device LED4, the fifth light-emitting device LED5, and the sixth light-emitting device LED6 arranged in each of the unit pixel areas UPXA can be turned off so that these light-emitting devices LED4, LED5, and LED6 do not emit light. Here, non-emission can be achieved by making the pixel not selected by the scan signal and therefore not receiving the data signal or by making the pixel selected by the scan signal but receiving a black data signal and showing black.

[0090] In the normal driving mode (wide viewing angle mode), the fourth to sixth light-emitting devices LED4, LED5, and LED6 arranged in each of the unit pixel areas UPXA can be selected by the scan signal and emit light having a brightness corresponding to the data signal. In the normal driving mode, according to an embodiment, the first to third light-emitting devices LED1, LED2, and LED3 arranged in each of the unit pixel areas UPXA may not emit light or selectively emit light. However, the present disclosure is not necessarily limited to this. For example, in the normal driving mode, the first to third light-emitting devices LED1, LED2, and LED3 arranged in each of the unit pixel areas UPXA may also emit light together with the fourth to sixth light-emitting devices LED4, LED5, and LED6.

[0091] The encapsulation layer ENC may be disposed on the first to sixth light emitting devices LED1, LED2, LED3, LED4, LED5, and LED6. The encapsulation layer ENC may protect the first to sixth light emitting devices LED1, LED2, LED3, LED4, LED5, and LED6 from external moisture, heat, impact, etc. Although not shown, the encapsulation layer ENC may include a first inorganic encapsulation layer, an organic encapsulation layer disposed on the first inorganic encapsulation layer, and a second inorganic encapsulation layer disposed on the organic encapsulation layer.

[0092] The light transmission layer LTL may be disposed on the encapsulation layer ENC. The light transmission layer LTL may define an opening that exposes the upper surface of the encapsulation layer ENC. For example, the opening may penetrate the light transmission layer LTL. In an embodiment, the light transmission layer LTL may have a grid shape in a plan view.

[0093] The light transmitting layer LTL may include an organic insulating material and / or an inorganic insulating material having relatively high light transmittance.

[0094] In an embodiment, a separate insulating layer may be additionally provided between the encapsulation layer ENC and the light transmission layer LTL. For example, a sensing layer including at least one touch electrode and at least one touch insulating layer may be provided between the encapsulation layer ENC and the light transmission layer LTL. In this case, the opening defined by the light transmission layer LTL may expose the upper surface of the insulating layer.

[0095] The partition pattern PW may be disposed on the encapsulation layer ENC. The partition pattern PW may be disposed in an opening defined in the light transmission layer LTL. For example, the partition pattern PW may contact an inner surface of the light transmission layer LTL defining the opening. Therefore, the light transmission layer LTL may be disposed between the partition patterns PW.

[0096] In an embodiment, Figure 4As shown in FIG. 1 , the partition patterns PW may extend in the first direction DR1 and be spaced apart from each other along the second direction DR2. In other words, the partition patterns PW may be parallel to each other. However, the arrangement structure of the partition patterns PW is not necessarily limited thereto.

[0097] At least one of the separation patterns PW may partially cover the first pixel opening PO1 in plan view, at least one of the separation patterns PW may partially cover the second pixel opening PO2 in plan view, and at least one of the separation patterns PW may partially cover the third pixel opening PO3 in plan view.

[0098] In other words, at least one of the partition patterns PW may extend in the first direction DR1 across the first pixel opening PO1, at least one of the partition patterns PW may extend in the first direction DR1 across the second pixel opening PO2, and at least one of the partition patterns PW may extend in the first direction DR1 across the third pixel opening PO3.

[0099] For example, Figure 4 As shown in , two of the partition patterns PW may extend continuously in the first direction DR1 across the first pixel opening PO1 and the second pixel opening PO2, and the other two partition patterns PW may extend in the first direction DR1 across the third pixel opening PO3. Figure 4 In a specific embodiment, each pair of partition patterns PW extends parallel to each other. However, the present disclosure is not necessarily limited thereto, and the number, length, and orientation of the partition patterns PW extending across the first to third pixel openings PO1, PO2, PO3 in a plan view may vary according to embodiments.

[0100] The partition pattern PW can adjust the viewing angle of light emitted from the first light emitting device to the third light emitting device LED1, LED2 and LED3. For example, light emitted from the first light emitting device to the third light emitting device LED1, LED2 and LED3 can be incident on the partition pattern PW. At least some of the light incident on the partition pattern PW can be absorbed or blocked by the partition pattern PW. Therefore, the partition pattern PW can adjust the viewing angle of light emitted from the first light emitting device to the third light emitting device LED1, LED2 and LED3.

[0101] In an embodiment, the separation pattern PW may include a material having relatively low transmittance and reflectance and relatively high absorptivity. For example, the separation pattern PW may include black dye, black pigment, carbon black, chrome, etc. These may be used alone or in combination with each other.

[0102] In an embodiment, the separation pattern PW may include molybdenum tantalum oxide (MTO). In this case, the separation pattern PW may have a multilayer structure. For example, the separation pattern PW may have a three-layer structure such as MTO / Mo / MTO, MTO / Cu / MTO, and MTO / Al / MTO. Alternatively, the separation pattern PW may have a double-layer structure such as MTO / Mo, MTO / Cu, and MTO / Al. However, the present disclosure is not necessarily limited thereto, and in other examples, the separation pattern PW may have a single-layer structure of MTO or a multilayer structure of four or more layers.

[0103] Meanwhile, the partition pattern PW may be spaced apart from the fourth to sixth pixel openings PO4, PO5, and PO6 in a plan view. In other words, the partition pattern PW may not overlap the fourth to sixth pixel openings PO4, PO5, and PO6 in a plan view.

[0104] Light emitted from the fourth to sixth light emitting devices LED4, LED5, and LED6 may not be incident on the partition pattern PW. Therefore, the partition pattern PW may not affect the viewing angle of light emitted from the fourth to sixth light emitting devices LED4, LED5, and LED6.

[0105] As described above, in the private drive mode, the first to third light-emitting devices LED1, LED2 and LED3 may emit light, and the fourth to sixth light-emitting devices LED4, LED5 and LED6 may not emit light. That is, in the private drive mode, among the light-emitting devices arranged in each of the unit pixel areas UPXA, the light-emitting device overlapped with the partition pattern PW may emit light, and the light-emitting device not overlapped with the partition pattern PW may not emit light. Therefore, the path of some of the light emitted from the light-emitting device in the private drive mode may be blocked and / or changed by the partition pattern PW. Therefore, when viewed obliquely from the left, right, upper or lower side of the display device 1, the user's field of view may be narrowed or blocked. In this way, the viewing angle of the display device 1 can be adjusted. That is, the display device 1 can be driven in a narrow viewing angle mode (i.e., a private drive mode).

[0106] In the normal driving mode, the fourth to sixth light emitting devices LED4, LED5, and LED6 may emit light. That is, in the normal driving mode, among the light emitting devices disposed in each of the unit pixel areas UPXA, the light emitting devices that do not overlap the partition pattern PW may emit light. Therefore, the display device 1 may be driven in a wide viewing angle mode.

[0107] Meanwhile, at least one of the partition patterns PW may not overlap all of the first to sixth pixel openings PO1, PO2, PO3, PO4, PO5, and PO6 in a plan view. That is, at least one of the partition patterns PW may be disposed only in the non-light emitting area NEA. However, the present disclosure is not necessarily limited thereto, and in another example, all of the partition patterns PW may overlap at least one of the first to third pixel openings PO1, PO2, and PO3 in a plan view.

[0108] When the partition pattern PW passes through each of the first to third pixel openings PO1 , PO2 , and PO3 , an effective opening area EO corresponding to each of the first to third pixel openings PO1 , PO2 , and PO3 may be defined.

[0109] Specifically, in a plan view, the effective opening area EO of the first pixel opening PO1 may be equal to the area of ​​the total area TA1 of the first pixel opening PO1 excluding the overlapping area covered by the partition pattern PW. Figure 4 As shown in, when the area of ​​the first pixel opening PO1 covered by one of the partition patterns PW is defined as the first area A1 and the area of ​​the first pixel opening PO1 covered by the other partition pattern PW is defined as the second area A2, the total coverage area of ​​the first pixel opening PO1 may be the sum of the first area A1 and the second area A2. That is, the total coverage area of ​​the first pixel opening PO1 may represent the total coverage area of ​​the first pixel opening PO1 covered by the partition pattern PW in the total area TA1 (covered and uncovered) of the first pixel opening PO1.

[0110] In a plan view, the effective opening area EO of the second pixel opening PO2 may be equal to the area TA2 of the second pixel opening PO2 excluding the total coverage area of ​​the second pixel opening PO2. Figure 4 As shown in , when the area of ​​the second pixel opening PO2 covered by one of the partition patterns PW is defined as the third area A3, and the area of ​​the second pixel opening PO2 covered by another partition pattern PW is defined as the fourth area A4, the total coverage area of ​​the second pixel opening PO2 may be the sum of the third area A3 and the fourth area A4. That is, the total coverage area of ​​the second pixel opening PO2 may represent the total coverage area of ​​the second pixel opening PO2 covered by the partition pattern PW in the total area TA2 (covered and uncovered) of the second pixel opening PO2.

[0111] In a plan view, the effective opening area EO of the third pixel opening PO3 may be equal to the area TA3 of the total area of ​​the third pixel opening PO3 excluding the total coverage area of ​​the third pixel opening PO3. Figure 4As shown in , when the area of ​​the third pixel opening PO3 covered by one of the partition patterns PW is defined as the fifth area A5, and the area of ​​the third pixel opening PO3 covered by another partition pattern PW is defined as the sixth area A6, the total coverage area of ​​the third pixel opening PO3 may be the sum of the fifth area A5 and the sixth area A6. That is, the total coverage area of ​​the third pixel opening PO3 may represent the total coverage area of ​​the third pixel opening PO3 covered by the partition pattern PW in the total area TA3 (covered and uncovered) of the third pixel opening PO3.

[0112] In the plan view, for the first pixel opening PO1, the second pixel opening PO2 and the third pixel opening PO3, the first overlap ratio, the second overlap ratio and the third overlap ratio may be substantially the same. The first overlap ratio is the ratio of the area of ​​the first pixel opening PO1 covered by the partition pattern PW to the total area TA1 of the first pixel opening PO1. The second overlap ratio is the ratio of the area of ​​the second pixel opening PO2 covered by the partition pattern PW to the total area TA2 of the second pixel opening PO2. The third overlap ratio is the ratio of the area of ​​the third pixel opening PO3 covered by the partition pattern PW to the total area TA3 of the third pixel opening PO3.

[0113] The first stacking ratio, the second stacking ratio, and the third stacking ratio may be substantially equal to each other. The first stacking ratio may be a ratio of the total coverage area of ​​the first pixel opening PO1 (i.e., the sum of the first area A1 and the second area A2) to the total area TA1 of the first pixel opening PO1. The second stacking ratio may be a ratio of the total coverage area of ​​the second pixel opening PO2 (i.e., the sum of the third area A3 and the fourth area A4) to the total area TA2 of the second pixel opening PO2. The third stacking ratio may be a ratio of the total coverage area of ​​the third pixel opening PO3 (i.e., the sum of the fifth area A5 and the sixth area A6) to the total area TA3 of the third pixel opening PO3.

[0114] In other words, the first aperture ratio, the second aperture ratio and the third aperture ratio may be substantially equal to each other. The first aperture ratio is the ratio of the area of ​​the first pixel opening PO1 not covered by the partition pattern PW to the total area TA1 of the first pixel opening PO1. The second aperture ratio is the ratio of the area of ​​the second pixel opening PO2 not covered by the partition pattern PW to the total area TA2 of the second pixel opening PO2. The third aperture ratio is the ratio of the area of ​​the third pixel opening PO3 not covered by the partition pattern PW to the total area TA3 of the third pixel opening PO3. The area of ​​the pixel opening not covered by the partition pattern PW is the area of ​​the portion of the pixel opening adjacent to the portion covered by the partition pattern PW.

[0115] That is, the ratio of the effective opening area EO of the first pixel opening PO1 to the total area TA1 of the first pixel opening PO1, the ratio of the effective opening area EO of the second pixel opening PO2 to the total area TA2 of the second pixel opening PO2, and the ratio of the effective opening area EO of the third pixel opening PO3 to the total area TA3 of the third pixel opening PO3 can be basically equal to each other.

[0116] Therefore, even when different portions of the partition pattern PW extend across each of the first pixel opening PO1, the second pixel opening PO2, and the third pixel opening PO3, the first pixel opening PO1, the second pixel opening PO2, and the third pixel opening PO3 may have substantially equal effective aperture ratios.

[0117] Therefore, even when the display device 1 includes the partition pattern PW for adjusting the viewing angle, the luminous efficiency of the first light emitting device LED1 corresponding to the first pixel opening PO1, the luminous efficiency of the second light emitting device LED2 corresponding to the second pixel opening PO2, and the luminous efficiency of the third light emitting device LED3 corresponding to the third pixel opening PO3 can be substantially equal to each other. Therefore, the life characteristics of the light emitting devices can be improved. Therefore, the life characteristics of the display device 1 can be improved.

[0118] Figure 6 and Figure 7 is a diagram showing a method according to an embodiment of the present invention. Figure 2 A plan view of a unit pixel region of a display device. For example, Figure 6 is a schematic diagram showing a Figure 2 A plan view of an arrangement of pixel electrodes and pixel defining layers of a display device, and Figure 7 is a schematic diagram showing a Figure 2 A plan view of an arrangement of light emitting devices and separation patterns of a display device.

[0119] Except for the first to sixth pixel openings PO1-1, PO2-1, PO3-1, PO4-1, PO5-1, and PO6-1, refer to Figure 6 and Figure 7 Each of the unit pixel areas UPXA described may be referred to as Figure 3 and Figure 4 The unit pixel area UPXA described in the following is basically the same as that of the reference pixel area UPXA. Figure 3 and Figure 4 The differences in the unit pixel areas described herein are excluded, and descriptions of duplicate contents will be omitted.

[0120] Reference Figure 6 and Figure 7, the pixel defining layer PDL may define a first pixel opening PO1-1 located above a portion of the first pixel electrode PE1, a second pixel opening PO2-1 located above a portion of the second pixel electrode PE2, a third pixel opening PO3-1 located above a portion of the third pixel electrode PE3, a fourth pixel opening PO4-1 located above a portion of the fourth pixel electrode PE4, a fifth pixel opening PO5-1 located above a portion of the fifth pixel electrode PE5, and a sixth pixel opening PO6-1 located above a portion of the sixth pixel electrode PE6. The pixel openings PO1-1, PO2-1, PO3-1, PO4-1, PO5-1, and PO6-1 pass through the pixel defining layer PDL to extend to surfaces of the first pixel electrode PE1, the second pixel electrode PE2, the third pixel electrode PE3, the fourth pixel electrode PE4, the fifth pixel electrode PE5, and the sixth pixel electrode PE6, respectively.

[0121] In an embodiment, the arrangement structure of the first to sixth pixel openings PO1-1, PO2-1, PO3-1, PO4-1, PO5-1, and PO6-1 defined in each of the unit pixel areas UPXA may be the same as that of the reference Figure 3 and Figure 4 The arrangement structures of the first to sixth pixel openings PO1, PO2, PO3, PO4, PO5, and PO6 described are substantially the same. That is, the arrangement structure of the first to sixth pixel openings PO1-1, PO2-1, PO3-1, PO4-1, PO5-1, and PO6-1 defined in each of the unit pixel areas UPXA may be an S-stripe structure.

[0122] In a plan view, a total area TA1-1 of the first pixel opening PO1-1 may be substantially equal to a total area TA4-1 of the fourth pixel opening PO4-1. In other words, an opening ratio of the first pixel opening PO1-1 may be substantially equal to an opening ratio of the fourth pixel opening PO4-1.

[0123] In an embodiment, the length of the long side of the first pixel opening PO1-1 and the length of the long side of the fourth pixel opening PO4-1 may be substantially the same, and the length of the short side of the first pixel opening PO1-1 and the length of the short side of the fourth pixel opening PO4 may be substantially the same. Therefore, the total area TA1-1 of the first pixel opening PO1-1 may be substantially equal to the total area TA4-1 of the fourth pixel opening PO4-1. However, the present disclosure is not necessarily limited thereto, and as long as the total area TA1-1 of the first pixel opening PO1-1 and the total area TA4-1 of the fourth pixel opening PO4-1 are the same, the planar shape of the first pixel opening PO1-1 and the planar shape of the fourth pixel opening PO4-1 may be changed in various ways.

[0124] In an embodiment, in a plan view, the total area TA2-1 of the second pixel opening PO2-1 and the total area TA5-1 of the fifth pixel opening PO5-1 may be different from each other. In other words, the opening ratio of the second pixel opening PO2-1 and the opening ratio of the fifth pixel opening PO5-1 may be different from each other.

[0125] For example, the total area TA2-1 of the second pixel opening PO2-1 may be greater than the total area TA5-1 of the fifth pixel opening PO5-1. In other words, the aperture ratio of the second pixel opening PO2-1 may be greater than the aperture ratio of the fifth pixel opening PO5-1.

[0126] In an embodiment, the long side of the second pixel opening PO2-1 may be defined as being longer than the long side of the fifth pixel opening PO5-1 in the first direction DR1. That is, the second pixel opening PO2-1 may be longer than the fifth pixel opening PO5-1 in the first direction DR1. In addition, the length of the short side of the second pixel opening PO2-1 and the length of the short side of the fifth pixel opening PO5-1 may be substantially the same. Therefore, the total area TA2-1 of the second pixel opening PO2-1 may be greater than the total area TA5-1 of the fifth pixel opening PO5-1. However, the present disclosure is not necessarily limited thereto, and as long as the total area TA2-1 of the second pixel opening PO2-1 is greater than the total area TA5-1 of the fifth pixel opening PO5-1, the planar shape of the second pixel opening PO2-1 and the planar shape of the fifth pixel opening PO5-1 may be changed in various ways.

[0127] In an embodiment, in a plan view, the total area TA3-1 of the third pixel opening PO3-1 and the total area TA6-1 of the sixth pixel opening PO6-1 may be different from each other. In other words, the opening ratio of the third pixel opening PO3-1 and the opening ratio of the sixth pixel opening PO6-1 may be different from each other.

[0128] For example, the total area TA3-1 of the third pixel opening PO3-1 may be greater than the total area TA6-1 of the sixth pixel opening PO6-1. In other words, the aperture ratio of the third pixel opening PO3-1 may be greater than the aperture ratio of the sixth pixel opening PO6-1.

[0129] In an embodiment, the long side of the third pixel opening PO3-1 may be defined as being longer than the long side of the sixth pixel opening PO6-1 in the first direction DR1. That is, the third pixel opening PO3-1 may be longer than the sixth pixel opening PO6-1 in the first direction DR1. In addition, the length of the short side of the third pixel opening PO3-1 and the length of the short side of the sixth pixel opening PO6-1 may be substantially the same. Therefore, the total area TA3-1 of the third pixel opening PO3-1 may be greater than the total area TA6-1 of the sixth pixel opening PO6-1. However, the present disclosure is not necessarily limited thereto, and as long as the total area TA3-1 of the third pixel opening PO3-1 is greater than the total area TA6-1 of the sixth pixel opening PO6-1, the planar shape of the third pixel opening PO3-1 and the planar shape of the sixth pixel opening PO6-1 may be changed in various ways.

[0130] Similar to the above embodiment, in the plan view, for the first pixel opening PO1-1, the second pixel opening PO2-1 and the third pixel opening PO3-1, the first overlap ratio, the second overlap ratio and the third overlap ratio may be substantially the same. The first overlap ratio is the ratio of the area of ​​the first pixel opening PO1-1 covered by the partition pattern PW to the total area TA1-1 of the first pixel opening PO1-1, the second overlap ratio is the ratio of the area of ​​the second pixel opening PO2-1 covered by the partition pattern PW to the total area TA2-1 of the second pixel opening PO2-1, and the third overlap ratio is the ratio of the area of ​​the third pixel opening PO3-1 covered by the partition pattern PW to the total area TA3-1 of the third pixel opening PO3-1.

[0131] The first overlapping ratio (i.e., the ratio of the sum of the first area A1-1 and the second area A2-1 to the total area TA1-1 of the first pixel opening PO1-1), the second overlapping ratio (i.e., the ratio of the sum of the third area A3-1 and the fourth area A4-1 to the total area TA2-1 of the second pixel opening PO2-1) and the third overlapping ratio (i.e., the ratio of the sum of the fifth area A5-1 and the sixth area A6-1 to the total area TA3-1 of the third pixel opening PO3-1) can be basically equal to each other.

[0132] In other words, the first aperture ratio, the second aperture ratio and the third aperture ratio may be substantially equal to each other. The first aperture ratio is the ratio of the area of ​​the first pixel opening PO1-1 not covered by the partition pattern PW to the total area TA1-1 of the first pixel opening PO1-1. The second aperture ratio is the ratio of the area of ​​the second pixel opening PO2-1 not covered by the partition pattern PW to the total area TA2-1 of the second pixel opening PO2-1. The third aperture ratio is the ratio of the area of ​​the third pixel opening PO3-1 not covered by the partition pattern PW to the total area TA3-1 of the third pixel opening PO3-1. As defined above, the area of ​​the pixel opening not covered by the partition pattern PW is the area of ​​the portion of the pixel opening adjacent to the portion covered by the partition pattern PW.

[0133] Figure 8 and Fig. 9 is a diagram showing a method according to an embodiment of the present invention. Figure 2 A plan view of a unit pixel region of a display device. For example, Figure 8 is a schematic diagram showing a Figure 2 A plan view of an arrangement of pixel electrodes and pixel defining layers of a display device, and Fig. 9 is a schematic diagram showing a Figure 2 A plan view of an arrangement of light emitting devices and separation patterns of a display device.

[0134] Except for the first to sixth pixel openings PO1-2, PO2-2, PO3-2, PO4-2, PO5-2, and PO6-2, refer to Figure 8 and Fig. 9 Each of the unit pixel areas UPXA described may be referred to as Figure 3 and Figure 4 The unit pixel area UPXA described in the following is basically the same as that of the reference pixel area UPXA. Figure 3 and Figure 4 The differences in the unit pixel areas described herein will be ignored, and descriptions of redundant contents will be omitted.

[0135] Reference Figure 8 and Fig. 9The pixel defining layer PDL may define a first pixel opening PO1-2 located above the first pixel electrode PE1 and extending to the first pixel electrode PE1, a second pixel opening PO2-2 located above the second pixel electrode PE2 and extending to the second pixel electrode PE2, a third pixel opening PO3-2 located above the third pixel electrode PE3 and extending to the third pixel electrode PE3, a fourth pixel opening PO4-2 located above the fourth pixel electrode PE4 and extending to the fourth pixel electrode PE4, a fifth pixel opening PO5-2 located above the fifth pixel electrode PE5 and extending to the fifth pixel electrode PE5, and a sixth pixel opening PO6-2 located above the sixth pixel electrode PE6 and extending to the sixth pixel electrode PE6.

[0136] In an embodiment, the arrangement structure of the first to sixth pixel openings PO1-2, PO2-2, PO3-2, PO4-2, PO5-2, and PO6-2 defined in each of the unit pixel areas UPXA may be the same as that of the reference Figure 3 and Figure 4 The arrangement structures of the first to sixth pixel openings PO1, PO2, PO3, PO4, PO5, and PO6 described are substantially the same. That is, the arrangement structure of the first to sixth pixel openings PO1-2, PO2-2, PO3-2, PO4-2, PO5-2, and PO6-2 defined in each of the unit pixel areas UPXA may be an S-stripe structure.

[0137] In an embodiment, in a plan view, the total area TA1-2 of the first pixel opening PO1-2 and the total area TA4-2 of the fourth pixel opening PO4-2 may be different from each other. In other words, the opening ratio of the first pixel opening PO1-2 and the opening ratio of the fourth pixel opening PO4-2 may be different from each other.

[0138] For example, the total area TA1-2 of the first pixel opening PO1-2 may be greater than the total area TA4-2 of the fourth pixel opening PO4-2. In other words, the opening ratio of the first pixel opening PO1-2 may be greater than the opening ratio of the fourth pixel opening PO4-2.

[0139] In an embodiment, in the first direction DR1, the long side of the first pixel opening PO1-2 may be longer than the long side of the fourth pixel opening PO4-2. That is, the first pixel opening PO1-2 may be longer than the fourth pixel opening PO4-2 in the first direction DR1. In addition, the length of the short side of the first pixel opening PO1-2 and the length of the short side of the fourth pixel opening PO4-2 may be substantially the same. Therefore, the total area TA1-2 of the first pixel opening PO1-2 may be greater than the total area TA4-2 of the fourth pixel opening PO4-2. However, the present disclosure is not necessarily limited thereto, and as long as the total area TA1-2 of the first pixel opening PO1-2 is greater than the total area TA4-2 of the fourth pixel opening PO4-2, the plane shape of the first pixel opening PO1-2 and the plane shape of the fourth pixel opening PO4-2 may be changed in various ways.

[0140] In an embodiment, in a plan view, the total area TA2-2 of the second pixel opening PO2-2 and the total area TA5-2 of the fifth pixel opening PO5-2 may be different from each other. In other words, the opening ratio of the second pixel opening PO2-2 and the opening ratio of the fifth pixel opening PO5-2 may be different from each other.

[0141] For example, the total area TA2-2 of the second pixel opening PO2-2 may be greater than the total area TA5-2 of the fifth pixel opening PO5-2. In other words, the aperture ratio of the second pixel opening PO2-2 may be greater than the aperture ratio of the fifth pixel opening PO5-2.

[0142] In an embodiment, in the first direction DR1, the long side of the second pixel opening PO2-2 may be longer than the long side of the fifth pixel opening PO5-2. That is, the second pixel opening PO2-2 may be longer than the fifth pixel opening PO5-2 in the first direction DR1. In addition, the length of the short side of the second pixel opening PO2-2 and the length of the short side of the fifth pixel opening PO5-2 may be substantially the same. Therefore, the total area TA2-2 of the second pixel opening PO2-2 may be greater than the total area TA5-2 of the fifth pixel opening PO5-2. However, the present disclosure is not necessarily limited thereto, and as long as the total area TA2-2 of the second pixel opening PO2-2 is greater than the total area TA5-2 of the fifth pixel opening PO5-2, the planar shape of the second pixel opening PO2-2 and the planar shape of the fifth pixel opening PO5-2 may be changed in various ways.

[0143] In an embodiment, in a plan view, the total area TA3-2 of the third pixel opening PO3-2 and the total area TA6-2 of the sixth pixel opening PO6-2 may be different from each other. In other words, the opening ratio of the third pixel opening PO3-2 and the opening ratio of the sixth pixel opening PO6-2 may be different from each other.

[0144] For example, the total area TA3-2 of the third pixel opening PO3-2 may be greater than the total area TA6-2 of the sixth pixel opening PO6-2. In other words, the aperture ratio of the third pixel opening PO3-2 may be greater than the aperture ratio of the sixth pixel opening PO6-2.

[0145] In an embodiment, in the first direction DR1, the long side of the third pixel opening PO3-2 may be longer than the long side of the sixth pixel opening PO6-2. That is, the third pixel opening PO3-2 may be longer than the sixth pixel opening PO6-2 in the first direction DR1. In addition, the length of the short side of the third pixel opening PO3-2 and the length of the short side of the sixth pixel opening PO6-2 may be substantially the same. Therefore, the total area TA3-2 of the third pixel opening PO3-2 may be greater than the total area TA6-2 of the sixth pixel opening PO6-2. However, the present disclosure is not necessarily limited thereto, and as long as the total area TA3-2 of the third pixel opening PO3-2 is greater than the total area TA6-2 of the sixth pixel opening PO6-2, the planar shape of the third pixel opening PO3-2 and the planar shape of the sixth pixel opening PO6-2 may be changed in various ways.

[0146] Similar to the above embodiment, in the plan view, refer to Figure 8 and Fig. 9 , the first overlap ratio, the second overlap ratio and the third overlap ratio may be equal to each other. The first overlap ratio is the ratio of the area of ​​the first pixel opening PO1-2 covered by the partition pattern PW to the total area TA1-2 of the first pixel opening PO1-2, the second overlap ratio is the ratio of the area of ​​the second pixel opening PO2-2 covered by the partition pattern PW to the total area TA2-2 of the second pixel opening PO2-2, and the third overlap ratio is the ratio of the area of ​​the third pixel opening PO3-2 covered by the partition pattern PW to the total area TA3-2 of the third pixel opening PO3-2.

[0147] That is, the first overlapping ratio (i.e., the ratio of the sum of the first area A1-2 and the second area A2-2 to the total area TA1-2 of the first pixel opening PO1-2), the second overlapping ratio (i.e., the ratio of the sum of the third area A3-2 and the fourth area A4-2 to the total area TA2-2 of the second pixel opening PO2-2) and the third overlapping ratio (i.e., the ratio of the sum of the fifth area A5-2 and the sixth area A6-2 to the total area TA3-2 of the third pixel opening PO3-2) can be basically equal to each other.

[0148] In other words, for the first pixel opening PO1-2, the second pixel opening PO2-2 and the third pixel opening PO3-2, the first opening ratio, the second opening ratio and the third opening ratio may be substantially the same. The first opening ratio is the ratio of the area of ​​the first pixel opening PO1-2 not covered by the partition pattern PW to the total area TA1-2 of the first pixel opening PO1-2, the second opening ratio is the ratio of the area of ​​the second pixel opening PO2-2 not covered by the partition pattern PW to the total area TA2-2 of the second pixel opening PO2-2, and the third opening ratio is the ratio of the area of ​​the third pixel opening PO3-2 not covered by the partition pattern PW to the total area TA3-2 of the third pixel opening PO3-2. As defined above, the area of ​​the pixel opening not covered by the partition pattern PW is the area of ​​the portion of the pixel opening adjacent to the portion covered by the partition pattern PW.

For example, the first pixel opening PO1-3, the second pixel opening PO2-3, the fourth pixel opening PO4-3, and the fifth pixel opening PO5-3 may be arranged in a first column, and the third pixel opening PO3-3 and the sixth pixel opening PO6-3 may be arranged in a second column adjacent to the first column.

[0152] In a plan view, the short side of each of the first pixel opening PO1-3, the second pixel opening PO2-3, the fourth pixel opening PO4-3, and the fifth pixel opening PO5-3 may extend in the first direction DR1. The long side of each of the third pixel opening PO3-3 and the sixth pixel opening PO6-3 may extend in the first direction DR1. The first pixel opening PO1-3, the fourth pixel opening PO4-3, the second pixel opening PO2-3, and the fifth pixel opening PO5-3 may be arranged in the first column spaced apart from each other so that their long sides face each other. The third pixel opening PO3-3 and the sixth pixel opening PO6-3 may be arranged in the second column spaced apart from each other so that their short sides face each other.

The number of the partition patterns PW' covering each of the first to third pixel openings PO1-3, PO2-3, PO3-3 in a plan view may be variously changed according to the embodiment.

[0154] In addition, the partition pattern PW′ may be spaced apart from the fourth to sixth pixel openings PO4-3, PO5-3, and PO6-3 in a plan view to avoid overlapping with the fourth to sixth pixel openings PO4-3, PO5-3, and PO6-3.

[0155] The total area TA3-3 of the third pixel opening PO3-3 and the total area TA6-3 of the sixth pixel opening PO6-3 may be different from each other. In other words, the opening ratio of the third pixel opening PO3-3 and the opening ratio of the sixth pixel opening PO6-3 may be different from each other.

[0156] For example, the total area TA3-3 of the third pixel opening PO3-3 may be greater than the total area TA6-3 of the sixth pixel opening PO6-3. In other words, the aperture ratio of the third pixel opening PO3-3 may be greater than the aperture ratio of the sixth pixel opening PO6-3.

[0157] In addition, in the plan view, for the first pixel opening PO1-3, the second pixel opening PO2-3 and the third pixel opening PO3-3, the first overlap ratio, the second overlap ratio and the third overlap ratio may be substantially the same. The first overlap ratio is the ratio of the area of ​​the first pixel opening PO1-3 covered by the partition pattern PW' to the total area TA1-3 of the first pixel opening PO1-3, the second overlap ratio is the ratio of the area of ​​the second pixel opening PO2-3 covered by the partition pattern PW' to the total area TA2-3 of the second pixel opening PO2-3, and the third overlap ratio is the ratio of the area of ​​the third pixel opening PO3-3 covered by the partition pattern PW' to the total area TA3-3 of the third pixel opening PO3-3.

The first aperture ratio is the ratio of the area of ​​the first pixel opening PO1-3 not covered by the partition pattern PW' to the total area TA1-3 of the first pixel opening PO1-3. The second aperture ratio is the ratio of the area of ​​the second pixel opening PO2-3 not covered by the partition pattern PW' to the total area TA2-3 of the second pixel opening PO2-3. The third aperture ratio is the ratio of the area of ​​the third pixel opening PO3-3 not covered by the partition pattern PW' to the total area TA3-3 of the third pixel opening PO3-3.

For example, the first pixel opening PO1-4, the second pixel opening PO2-4 and the third pixel opening PO3-4 may be arranged in the first column, and the fourth pixel opening PO4-4, the fifth pixel opening PO5-4 and the sixth pixel opening PO6-4 may be arranged in the second column adjacent to the first column. At this time, the first pixel opening PO1-4, the second pixel opening PO2-4 and the third pixel opening PO3-4 may be arranged in the first column along the oblique direction relative to both the first direction DR1 and the second direction DR2. In addition, the fourth pixel opening PO4-4, the fifth pixel opening PO5-4 and the sixth pixel opening PO6-6 may be arranged in the second column along the oblique direction relative to both the first direction DR1 and the second direction DR2.

The number of separation patterns PW" covering each of the first to third pixel openings PO1-4, PO2-4, PO3-4 in a plan view may be variously changed according to the embodiment.

[0164] In addition, the separation pattern PW" may be spaced apart from the fourth to sixth pixel openings PO4-4, PO5-4 and PO6-4 in a plan view. In other words, in a plan view, the separation pattern PW" may not cover any portion of the fourth to sixth pixel openings PO4-4, PO5-4 and PO6-4.

[0165] In a plan view, the total area TA3-4 of the third pixel opening PO3-4 and the total area TA6-4 of the sixth pixel opening PO6-4 may be different from each other. In other words, the opening ratio of the third pixel opening PO3-4 and the opening ratio of the sixth pixel opening PO6-4 may be different from each other.

[0166] For example, the total area TA3-4 of the third pixel opening PO3-4 may be greater than the total area TA6-4 of the sixth pixel opening PO6-4. In other words, the aperture ratio of the third pixel opening PO3-4 may be greater than the aperture ratio of the sixth pixel opening PO6-4.

[0167] In addition, in the plan view, the first overlapping ratio, the second overlapping ratio and the third overlapping ratio may be substantially equal to each other.

The third overlapping ratio is the ratio of the area of ​​the third pixel opening PO3-4 covered by the partition pattern PW" to the total area TA3-4 of the third pixel opening PO3-4.

[0168] In other words, the first opening ratio, the second opening ratio and the third opening ratio may be substantially equal to each other. The first opening ratio is the ratio of the area of ​​the first pixel opening PO1-4 not covered by the partition pattern PW" to the total area TA1-4 of the first pixel opening PO1-4. The second opening ratio is the ratio of the area of ​​the second pixel opening PO2-4 not covered by the partition pattern PW" to the total area TA2-4 of the second pixel opening PO2-4. The third opening ratio is the ratio of the area of ​​the third pixel opening PO3-4 not covered by the partition pattern PW" to the total area TA3-4 of the third pixel opening PO3-4.

[0169] At the same time, Fig.10 and Fig.11 In the embodiment, the total area TA1-4 of the first pixel opening PO1-4 and the total area TA4-4 of the fourth pixel opening PO4-4 are substantially the same, and the total area TA2-4 of the second pixel opening PO2-4 and the total area TA5-4 of the fifth pixel opening PO5-4 are substantially the same. However, the present disclosure is not necessarily limited thereto.

[0170] In a display device 1 including a partition pattern to be driven in a wide viewing angle mode and a narrow viewing angle mode, respectively, if, in each of the unit pixel areas UPXA, the pixel openings corresponding to the light-emitting devices emitting light of the same color have the same total area (i.e., aperture ratio), then depending on the planar shape of each of the pixel openings and / or the color of light emitted by the corresponding light-emitting device, a deviation in the effective aperture ratio may occur between the pixel openings overlapping the partition pattern.

[0171] According to some embodiments, in a plan view, the display device 1 may have a structure in which the total area of ​​each of the pixel openings defined in each of the unit pixel regions and corresponding to the light emitting devices emitting light of the same color is different. Therefore, in the display device 1 according to some embodiments, the pixel openings partially covered by the partition pattern may have the same effective aperture ratio.

[0172] That is, even when the display device 1 includes a partition pattern for adjusting the viewing angle, according to the planar shape of each of the pixel openings and / or the color of the light emitted by the corresponding light-emitting device, no deviation in the effective aperture ratio occurs between the pixel openings overlapping the partition pattern. Therefore, the luminous efficiency of the light-emitting devices overlapping the partition pattern can be substantially the same. Therefore, the life characteristics of the light-emitting devices overlapping the partition pattern can be improved. Therefore, the life characteristics of the display device 1 can be improved.
