[0038] Throughout the drawings and the detailed description, unless otherwise described, the same reference numerals should be understood to refer to the same elements, features, and structures. For clarity, illustration, and convenience, the dimensions, lengths, and thicknesses of layers, regions, and elements, and their descriptions may be exaggerated. Detailed Description

[0039] Reference will now be made in detail to the embodiments of the present disclosure, examples of which are illustrated in the drawings. Wherever possible, the same reference numerals will be used throughout the drawings to refer to the same or like parts. The advantages and features of the present disclosure and the methods of achieving them will be clarified by the following embodiments described with reference to the drawings. However, the present disclosure may be embodied in different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the present disclosure to those skilled in the art.

[0040] The shapes, dimensions, ratios, angles, and numbers disclosed in the drawings used to describe the embodiments of the present disclosure are merely examples, and thus the present disclosure is not limited to the details shown. Similar reference numerals always refer to similar elements. In the following description, when the detailed description of related known functions or configurations is determined to unnecessarily obscure the gist of the present disclosure, the detailed description will be omitted.

[0041] In cases where "comprising", "having", and "including" are used in the description of this specification, another component may be added unless "only" is used. Unless otherwise indicated, terms in the singular form may include the plural form.

[0042] When interpreting an element, although the error range is not explicitly described, the element is interpreted to include the error range.

[0043] When describing a positional relationship, for example, when the positional relationship between two components is described as "on", "above", "below", and "adjacent to", unless "only" or "directly" is used, one or more other components may be provided between the two components.

[0044] When describing a temporal relationship, for example, when the time sequence is described as "after", "subsequently", "then", and "before", unless "only" or "directly" is used, discontinuous cases may be included.

[0045] It will be understood that although the terms "first", "second", etc. may be used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another. For example, without departing from the scope of the present disclosure, a first element may be referred to as a second element, and similarly, a second element may be referred to as a first element.

[0046] When describing the elements of the present disclosure, terms such as "first", "second", "A", "B", "(a)", "(b)", etc. may be used. These terms are intended to identify the corresponding elements from other elements, and these terms are not used to define the nature, basis, order, or number of the elements. For the expression that an element "is connected", "is coupled", or "is in contact" with another element, unless otherwise specified, the element can not only be directly connected, coupled, or in contact with another element, but also be indirectly connected, coupled, or in contact with another element, with one or more intermediate elements inserted between the elements.

[0047] The term "at least one" should be understood to include any and all combinations of one or more of the associated listed items. For example, the meaning of "at least one of the first item, the second item, and the third item" represents all combinations of two or more items selected from the first item, the second item, and the third item, as well as the first item, the second item, or the third item.

[0048] The "X-axis direction", "Y-axis direction", and "Z-axis direction" should not be interpreted only by the geometric relationship of being perpendicular to each other, and can have a wider directivity within the range where the elements of the present disclosure can function.

[0049] As can be fully understood by those skilled in the art, the features of various embodiments of the present disclosure can be partially or wholly coupled or combined with each other, and can interoperate with each other in various ways and be technically driven. The embodiments of the present disclosure can be executed independently of each other, or can be executed together in a mutually dependent relationship.

[0061] According to an embodiment of the present disclosure, the angle of the light emitted from each of the first emission portion and the second emission portion may be different from the angle of the light transmitted through the light transmissive portion. For example, the light transmissive surface of the light transmissive portion may be parallel to the substrate 100, and the light extraction surface (or emission surface) of each of the first emission portion and the second emission portion may be inclined or sloped with respect to the substrate 100.

One end of the pixel electrode PE adjacent to the circuit region CA may be electrically connected to the source electrode 117b of the driving thin film transistor Tdr through an electrode contact hole ECH provided in the protective layer 130 and the passivation layer 119.

[0144] According to an embodiment of the present disclosure, the pixel electrode PE at the emission area EA of each of the plurality of sub-pixels SP1 to SP4 may include a first pixel electrode PE1 and a second pixel electrode PE2.

[0145] The first pixel electrode PE1 may be formed (or disposed) over the second surface (or the first ramp surface) 150b of the pattern portion 150. The first pixel electrode PE1 may have a size larger than the size of the second surface 150b of the pattern portion 150. For example, a first edge portion of the first pixel electrode PE1 adjacent to the first surface of the pattern portion 150 may contact an edge portion of the first surface 150a of the pattern portion 150. For example, a second edge portion of the first pixel electrode PE1 opposite to the first edge portion may contact a portion of the protective layer 130 adjacent to the pattern portion 150. A central portion between the first edge portion and the second edge portion of the first pixel electrode PE1 may contact the second surface 150b of the pattern portion 150 and may be inclined or ramped to correspond to the second surface 150b of the pattern portion 150.

[0146] The second pixel electrode PE2 may be formed (or disposed) over the third surface (or the second ramp surface) 150c of the pattern portion 150. The second pixel electrode PE2 may have a size larger than the size of the third surface 150c of the pattern portion 150.

[0147] According to an embodiment of the present disclosure, each of the first pixel electrode PE1 and the second pixel electrode PE2 may be spaced apart from each other (or electrically disconnected) at the emission region EA and may be commonly connected to the pixel circuit PC at the circuit region CA. For example, the pixel circuit PC configured at each of the plurality of sub-pixels SP1 to SP4 may include a thin film transistor (TFT) Tdr commonly connected to the first pixel electrode PE1 and the second pixel electrode PE2.

The emission layer EL can be a common layer commonly formed (or disposed) at each of a plurality of sub-pixels SP1 to SP4. For example, the emission layer EL can be formed (or disposed) at other regions of each of the plurality of sub-pixels SP1 to SP4 except for the light transmission portion TP. For example, the emission layer EL can not be provided (or disposed) at the light transmission portion TP in each of the plurality of sub-pixels SP1 to SP4. For example, the region of the emission layer EL corresponding (or overlapping) to the light transmission portion TP of each of the plurality of sub-pixels SP1 to SP4 can be removed. For example, the emission layer EL can include an opening portion (or opening region or removal region) corresponding (or overlapping) to the light transmission portion TP of each of the plurality of sub-pixels SP1 to SP4.

The common electrode CE may be formed (or configured) at other regions of each of the plurality of sub-pixels SP1 to SP4 except for the light transmission portion TP. For example, the common electrode CE may not be provided (or configured) at the light transmission portion TP in each of the plurality of sub-pixels SP1 to SP4. For example, a region of the common electrode CE corresponding (or overlapping) to the light transmission portion TP of each of the plurality of sub-pixels SP1 to SP4 may be removed. For example, the common electrode CE may include an opening portion (or opening region or removal region) corresponding (or overlapping) to the light transmission portion TP of each of the plurality of sub-pixels SP1 to SP4.

[0155] The common electrode CE according to an embodiment of the present disclosure may include a metal material having a high reflectivity to reflect incident light emitted from the emission layer EL toward the substrate 100. The common electrode CE may include an opaque conductive material having a high reflectivity. For example, the common electrode CE may include a single-layer structure or a multi-layer structure of any one material selected from aluminum (Al), silver (Ag), molybdenum (Mo), titanium (Ti), or copper (Cu) or an alloy of two or more materials selected from aluminum (Al), silver (Ag), molybdenum (Mo), titanium (Ti), or copper (Cu). For example, the common electrode CE may be formed in a three-layer structure of IZO / MoTi / ITO or ITO / MoTi / ITO, or may be formed in a four-layer structure of ITO / Cu / MoTi / ITO, but the embodiments of the present disclosure are not limited thereto.

[0156] The light-emitting device ED can generate light in response to the current supplied from the pixel circuit PC and thus can emit light. According to an embodiment of the present disclosure, the pixel electrode PE, the emission layer EL, and the common electrode CE formed above the pattern portion 150 can configure (or implement) the first emission portion EP1 and the second emission portion EP2.

[0157] The first emission portion EP1 can include the first pixel electrode PE1, the emission layer EL, and the common electrode CE formed (or configured) above the second surface (or the first ramp surface) 150b of the pattern portion 150. The first emission portion EP1 can emit light through the light emission of the emission layer EL according to the current applied from the pixel circuit PC to the first pixel electrode PE1.

[0158] The second emission portion EP2 can include the second pixel electrode PE2, the emission layer EL, and the common electrode CE formed (or configured) above the third surface (or the second ramp surface) 150c of the pattern portion 150. The second emission portion EP2 can emit light through the light emission of the emission layer EL according to the current applied from the pixel circuit PC to the second pixel electrode PE2.

[0159] The emission layer EL at each of the first emission portion EP1 and the second emission portion EP2 can emit light simultaneously when the current is commonly supplied from the driving thin-film transistor Tdr of the pixel circuit PC to the first pixel electrode PE1 and the second pixel electrode PE2 through the electrode connection line ECL.

[0160] According to an embodiment of the present disclosure, the light transmission portion TP can be provided (or configured) at the first surface 150a of the pattern portion 150 having a flat structure (or a planarized structure), and thus the light (or the first light or the transmitted light) TL passing through (or transmitting through) the light transmission portion TP can be output in a direction perpendicular to the first surface 100a of the substrate 100. Therefore, a user (or a viewer) can see the things or the background provided at the rear surface or the front surface of the light-emitting display device through the light transmission portion TP of each of the plurality of sub-pixels SP.

[0161] According to an embodiment of the present disclosure, the first emission unit EP1 may include an emission layer EL having a ramp structure disposed (or configured) above the first pixel electrode PE1, and thus light (or second light or first viewing angle light) L1 emitted from the emission layer EL of the first emission unit EP1 may be output in a direction inclined with respect to the first surface 100a of the substrate 100. For example, the light L1 emitted from the first emission unit EP1 may be output from the second surface 150b of the pattern unit 150 in a direction inclined with respect to the first surface 100a of the substrate 100. In addition, the light L1 emitted from the first emission unit EP1 may be output in a direction inclined with respect to the first surface 100a of the substrate 100 due to the refractive index difference at the first ramp surface 150b of the pattern unit 150. Therefore, the light output angle of the light L1 emitted from the first emission unit EP1 may be different from the angle of the light TL passing through the light transmission unit TP.

[0162] According to an embodiment of the present disclosure, as Figure 6 shown, a first angle (or interior angle) θ1 between the upper surface (or flat surface) 130a of the protective layer 130 and the second surface 150b of the pattern unit 150 may be an acute angle. For example, the light extraction efficiency of the light L1 emitted from the first emission unit EP1 may be determined based on the first angle θ1. For example, with respect to the light output surface (or light extraction surface) 100b of the substrate 100, the light extraction efficiency of the light L1 emitted from the first emission unit EP1 may be affected by: the angle of the light emitted from the first emission unit EP1, the angle of the light emitted from the first emission unit EP1 to the pattern unit 150, and the angle of the light emitted from the light output surface 100b of the substrate 100 to the outside. For example, the first angle θ1 may be set such that the angle of the light L1 emitted from the first emission unit EP1 and output to the outside of the light output surface 100b of the substrate 100 is greater than 30 degrees and less than 45 degrees, and thus the light extraction efficiency of the light L1 emitted from the first emission unit EP1 may be increased or maximized.

[0163] According to an embodiment of the present disclosure, the first angle θ1 may be equal to each other at each of the plurality of sub-pixels SP1 to SP4, but the embodiments of the present disclosure are not limited thereto. For example, the first angle θ1 may be different at one or more of the plurality of sub-pixels SP1 to SP4. For example, the first angle θ1 may be different at each of the red sub-pixel, blue sub-pixel, white sub-pixel, and green sub-pixel. That is, the first angle θ1 may be different for each sub-pixel.

[0164] According to an embodiment of the present disclosure, the second emission part EP2 may include an emission layer EL having a ramp structure disposed (or configured) above the second pixel electrode PE2, and thus the light (or third light or second viewing angle light) L2 emitted from the emission layer EL of the second emission part EP2 may be output in a direction inclined with respect to the first surface 100a of the substrate 100. For example, the light L2 emitted from the second emission part EP2 may be output from the third surface 150c of the pattern part 150 in a direction inclined with respect to the first surface 100a of the substrate 100. In addition, the light L2 emitted from the second emission part EP2 may be output in a direction inclined with respect to the first surface 100a of the substrate 100 due to the refractive index difference at the second ramp surface 150c of the pattern part 150. Accordingly, the light output angle of the light L2 emitted from the second emission part EP2 may be different from the angle of the light TL passing through the light transmission part TP.

[0165] According to an embodiment of the present disclosure, a second angle (or inner angle) θ2 between the upper surface (or flat surface) 130a of the protective layer 130 and the third surface 150c of the pattern part 150 may be an acute angle. For example, the second angle θ2 may be equal to or different from the first angle θ1 described above with reference to Figure 6 For example, similar to the first angle θ1 described above with reference to Figure 6 The second angle θ2 may be set such that the angle of the light L2 emitted from the second emission part EP2 and output to the outside of the light output surface 100b of the substrate 100 is greater than 30 degrees and less than 45 degrees, and thus the light extraction efficiency of the light L2 emitted from the second emission part EP2 may be improved or maximized.

[0166] The light-emitting display device (or light-emitting display panel) according to an embodiment of the present disclosure may further include a bank layer 170.

[0167] The bank layer 170 may be formed (or configured) to cover the edge portions of each of the plurality of emission parts or each of the first emission part EP1 and the second emission part EP2 at each of the plurality of sub-pixels SP or the entire light transmission part TP. The bank layer 170 may be formed of an organic material (e.g., a benzocyclobutene (BCB)-based resin, an acrylic-based resin, a polyimide resin, etc.). For example, the bank layer 170 may be formed of a transparent material and may be a transparent bank.

[0168] According to an embodiment of the present disclosure, as Figure 5As shown, the bank layer 170 may be formed (or configured) to cover all of the light transmissive portions TP of each of the plurality of sub-pixels SP. For example, in each of the plurality of sub-pixels SP, the bank layer 170 may be formed above the first surface 150a of the pattern portion 150 and may be configured to cover all of the first surface 150a of the pattern portion 150. The bank layer 170 disposed above the first surface 150a of the pattern portion 150 may provide a flat surface above the first surface 150a of the pattern portion 150 and may thus minimize changes in the optical path passing through the light transmissive portion TP.

[0169] According to an embodiment of the present disclosure, as Figure 4 and Figure 5 shown, the bank layer 170 may be formed (or configured) to cover the edge portions of each of the pixel electrodes PE at each of the plurality of sub-pixels SP. In each of the plurality of sub-pixels SP, the bank layer 170 may be formed (or configured) to cover the edge portions of each of the first pixel electrode PE1 and the second pixel electrode PE2. For example, the bank layer 170 disposed above the first surface 150a of the pattern portion 150 may be formed (or configured) to cover the edge portions of each of the first pixel electrode PE1 and the second pixel electrode PE2 adjacent to the light transmissive portion TP. In addition, the bank layer 170 may be formed above the protective layer 130 between adjacent sub-pixels SP1 to SP4.

[0170] According to an embodiment of the present disclosure, the light transmissive portion TP may correspond to another portion of the first surface 150a of the pattern portion 150 except for the edge portion covered by the bank layer 170 and may have a first width W1 in the first direction X. The first emission portion EP1 may correspond to another portion of the first pixel electrode PE1 except for the edge portion covered by the bank layer 170 and may have a second width W2 in the first direction X. The second emission portion EP2 may correspond to another portion of the second pixel electrode PE2 except for the edge portion covered by the bank layer 170 and may have a third width W3 in the first direction X. For example, the first width W1 of the light transmissive portion TP may be greater than the second width W2 of the first emission portion EP1 and the third width W3 of the second emission portion EP2. The second width W2 of the first emission portion EP1 and the third width W3 of the second emission portion EP2 may be equal to each other. The first width W1 of the light transmissive portion TP may be equal to the sum of the second width W2 of the first emission portion EP1 and the third width W3 of the second emission portion EP2, but is not limited thereto. For example, the first width W1 of the light transmissive portion TP may be greater than or less than the sum of the second width W2 of the first emission portion EP1 and the third width W3 of the second emission portion EP2.

[0171] A light-emitting display device (or a light-emitting display panel) according to an embodiment of the present disclosure may further include a non-emitting portion NEP corresponding to the bank layer 170. For example, an emission region EA of each of the plurality of pixels P may further include a first non-emitting portion NEP1 corresponding to the bank layer 170 between the light-transmitting portion TP and the first emission portion EP1, a second non-emitting portion NEP2 corresponding to the bank layer 170 between the light-transmitting portion TP and the second emission portion EP2, and a third non-emitting portion NEP3 corresponding to the bank layer 170 between adjacent sub-pixels SP1 to SP4.

[0172] According to an embodiment of the present disclosure, an emission layer EL of the light-emitting device ED may be formed (or disposed) above the pixel electrode PE and the bank layer 170. For example, the bank layer 170 may be formed between the emission layer EL and the pixel electrode PE, or may be formed between the emission layer EL and the protective layer 130.

The color filter layer 120 according to another embodiment of the present disclosure may be disposed between the interlayer insulating layer 115 and the passivation layer 119, or may be disposed between the substrate 100 and the interlayer insulating layer 115 to overlap the emission region EA.

[0175] The color filter layer 120 may have a size larger than that of the emission region EA. For example, when the color filter layer 120 has a size larger than that of the emission region EA, light leakage of light traveling toward adjacent sub-pixels SP1 to SP4 through its interior may be reduced or minimized.

[0176] The color filter layer 120 according to an embodiment of the present disclosure may include color filters that transmit only wavelengths of colors provided in each of the sub-pixels SP1 to SP4 of light emitted (or extracted) from the light-emitting device ED toward the substrate 100.

For example, the color filter layer 120 provided at the first sub-pixel SP1 may include a red color filter 121, the color filter layer 120 provided at the second sub-pixel SP2 may include a blue color filter 122, and the color filter layer 120 provided at the fourth sub-pixel SP4 may include a green color filter 123. The third sub-pixel SP3 may not include the color filter layer 120, or may include a transparent material to compensate for a step difference between adjacent pixels, thereby emitting white light.

[0177] According to another embodiment of the present disclosure, when each of the plurality of pixels P includes a red sub-pixel SP1, a blue sub-pixel SP2, and a green sub-pixel SP4, the color filter layer 120 may be omitted.

[0191] The first ramp surface (or first inclined surface) 153a may be inclined or ramped with respect to the upper surface 151a of the first pattern layer 151 (or the first surface 150a of the pattern portion 150) and / or the substrate 100. The first ramp surface 153a may be spaced apart from the first side surface 151b of the first pattern layer 151 (or the second surface 150b of the pattern portion 150). The first ramp surface 153a may be parallel to the first side surface 151b of the first pattern layer 151 (or the second surface 150b of the pattern portion 150), but is not limited thereto. For example, the first ramp surface 153a may overlap with the bank layer 170 covering the edge portion of the first emission portion EP1, but is not limited thereto. For example, the first ramp surface 153a may overlap with the edge portion of the light transmission portion TP to be spaced apart from the first emission portion EP1. For example, a part of the first ramp surface 153a may overlap with the first pixel electrode PE1 of the first emission portion EP1, but is not limited thereto and may not overlap with the first pixel electrode PE1 of the first emission portion EP1. For example, the first ramp surface 153a may be a side surface, a side ramp surface, a side inclined surface, a first ramp surface, a first inclined surface, or a first light refraction surface of the first pattern layer 151.

[0192] According to an embodiment of the present disclosure, a third angle (or interior angle) θ3 between the first ramp surface 153a and the flat surface 130a of the protective layer 130 may be equal to or different from a first angle (or interior angle) θ1 between the first side surface 151b of the first pattern layer 151 (or the second surface 150b of the pattern portion 150) and the flat surface 130a of the protective layer 130.

The third angle θ3 may be equal to each other at each of the plurality of sub-pixels SP1 to SP4, but the embodiments of the present disclosure are not limited thereto. For example, the third angle θ3 may be different at one or more of the plurality of sub-pixels SP1 to SP4. For example, the third angle θ3 may be different at each of a red sub-pixel, a blue sub-pixel, a white sub-pixel, and a green sub-pixel. That is, the third angle θ3 may be different for each sub-pixel.

[0193] The second ramp surface (or second inclined surface) 153b may be inclined or ramped with respect to the upper surface 151a of the first pattern layer 151 (or the first surface 150a of the pattern portion 150) and / or the substrate 100. The second ramp surface 153b may be spaced apart from the second side surface 151c of the first pattern layer 151 (or the third surface 150c of the pattern portion 150). The second ramp surface 153b may be parallel to the second side surface 151c of the first pattern layer 151 (or the third surface 150c of the pattern portion 150), but is not limited thereto. For example, the second ramp surface 153b may overlap with the bank layer 170 covering the edge portion of the second emission portion EP2, but is not limited thereto. For example, the second ramp surface 153b may overlap with the edge portion of the light transmission portion TP to be spaced apart from the second emission portion EP2. For example, a part of the second ramp surface 153b may overlap with the second pixel electrode PE2 of the second emission portion EP2, but is not limited thereto and may not overlap with the second pixel electrode PE2 of the second emission portion EP2. For example, the second ramp surface 153b may be the other side surface, the other ramp surface, the other inclined surface, the second ramp surface, the second inclined surface, or the second light refraction surface of the first pattern layer 151.

[0194] According to an embodiment of the present disclosure, a fourth angle (or interior angle) θ4 between the second ramp surface 153b and the flat surface 130a of the protective layer 130 may be equal to or different from a second angle (or interior angle) θ2 between the second side surface 151c of the first pattern layer 151 (or the third surface 150c of the pattern portion 150) and the flat surface 130a of the protective layer 130. The fourth angle θ4 may be less than or equal to the second angle θ2. For example, the fourth angle θ4 may be less than or equal to the second angle θ2 within an acute angle range. The fourth angle θ4 may be equal to each other at each of the plurality of sub-pixels SP1 to SP4, but embodiments of the present disclosure are not limited thereto. For example, the fourth angle θ4 may be different at one or more of the plurality of sub-pixels SP1 to SP4. For example, the fourth angle θ4 may be different at each of a red sub-pixel, a blue sub-pixel, a white sub-pixel, and a green sub-pixel. That is, the fourth angle θ4 may be different for each sub-pixel.

[0195] The second pattern layer 155 may be formed (or configured) to prevent color mixing between the light L1 emitted from the first emission unit EP1 and the light L2 emitted from the second emission unit EP2. In addition, the second pattern layer 155 may be formed (or configured) to block the optical path between the light L1 emitted from the first emission unit EP1 and the light L2 emitted from the second emission unit EP2. The second pattern layer 155 may be formed (or configured) at the groove portion 153. The second pattern layer 155 may be formed (or configured) to be filled into the groove portion 153.

[0196] The upper surface (or upper side surface) 155a of the second pattern layer 155 may be provided (or configured) as a flat surface. The upper surface 155a of the second pattern layer 155 may form (or configure) the first surface 150a of the pattern portion 150. For example, the first surface (or upper surface) 150a of the pattern portion 150 may include the upper surface 151a of the first pattern layer 151 and the upper surface 155a of the second pattern layer 155. For example, the first surface (or upper surface) 150a of the pattern portion 150 may be provided (or configured) as a flat surface by the upper surface 151a of the first pattern layer 151 and the upper surface 155a of the second pattern layer 155. The upper surface 155a of the second pattern layer 155 may be covered by the bank layer 170.

[0197] The first pattern layer 151 and the second pattern layer 155 may be formed (or configured) to have different refractive indices. The first pattern layer 151 and the second pattern layer 155 may be formed (or configured) by organic materials having different refractive indices. For example, the refractive index of the second pattern layer 155 may be lower than the refractive index of the first pattern layer 151. For example, the second pattern layer 155 may be formed (or configured) with a material or an organic material having a refractive index lower than that of the first pattern layer 151. For example, the first pattern layer 151 may be a high refractive layer or a high refractive pattern layer. The second pattern layer 155 may be a low refractive layer or a low refractive pattern layer. For example, the first pattern layer 151 may be formed (or configured) with the same material as the protective layer 130, but is not limited thereto.

[0198] According to an embodiment of the present disclosure, the light L1 emitted from the first emission portion EP1 and the light L2 emitted from the second emission portion EP2 may be output in an inclined direction relative to the first surface 100a of the substrate 100 due to the refractive index difference between the first pattern layer 151 and the second pattern layer 152 of the pattern portion 150. For example, the light L1 emitted from the first emission portion EP1 may be output in an inclined direction relative to the first surface 100a of the substrate 100 due to the refractive index difference at the first slope surface 153a of the groove portion 153. The light L2 emitted from the second emission portion EP2 may be output in an inclined direction relative to the first surface 100a of the substrate 100 due to the refractive index difference at the second slope surface 153b of the groove portion 153.

[0199] According to an embodiment of the present disclosure, light L1 emitted from the first emission part EP1 traveling to the second emission part EP2 may be blocked by the second pattern layer 155. Light L2 emitted from the second emission part EP2 traveling to the first emission part EP1 may be blocked by the second pattern layer 155. Therefore, color mixing between the light L1 emitted from the first emission part EP1 and the light L2 emitted from the second emission part EP2 may be prevented or minimized.

[0200] According to the above reference Figure 2 and Figure 7 Another embodiment of the present disclosure described herein can provide a light-emitting display device according to the above reference Figures 2 to 6 The effect of the light emitting display device of the embodiment of the present disclosure described above is the same as that of the light emitting display device, and color mixing between the light L1 emitted from the first emission part EP1 and the light L2 emitted from the second emission part EP2 may be prevented or minimized by the second pattern layer 155 .

[0201] Refer to above Figure 2 and Figure 7In the description of the pattern portion 150 described above, the groove portion 153 has been described as including a trapezoidal cross-sectional structure that includes a first ramp surface 153a and a second ramp surface 153b of the groove portion 153, but embodiments of the present disclosure are not limited thereto. For example, as Figure 8 shown, the groove portion 153 of the pattern portion 150 may be configured to include a curved structure.

[0202] Referring to Figure 2 and Figure 8 , according to another embodiment of the present disclosure, the groove portion 153 may be formed (or configured) to be recessed from the upper surface 151a of the first pattern layer 151 that overlaps with the light transmission portion TP (or the first surface 150a of the pattern portion 150). The groove portion 153 may be formed (or configured) to be recessed (or made concave) from the upper surface 151a of the first pattern layer 151 (or the first surface 150a of the pattern portion 150) to include a curved surface 153c. For example, the groove portion 153 may include a cross-sectional structure that includes the curved surface 153c. For example, the groove portion 153 may include a semi-circular cross-sectional shape, a semi-elliptical cross-sectional shape, or a parabolic cross-sectional shape. The second pattern layer 155 may be filled into the groove portion 153.

[0203] According to another embodiment of the present disclosure, the light L1 emitted from the first light emitting portion EP1 may be output in a direction inclined with respect to the first surface 100a of the substrate 100 due to the refractive index difference on the curved surface 153c of the groove portion 153. The light L2 emitted from the second light emitting portion EP2 may be output in a direction inclined with respect to the first surface 100a of the substrate 100 due to the refractive index difference on the curved surface 153c of the groove portion 153.

[0204] According to another embodiment of the present disclosure, the light L1 emitted from the first emitting portion EP1 traveling to the second emitting portion EP2 may be blocked by the second pattern layer 155 filled in the groove portion 153. The light L2 emitted from the second emitting portion EP2 traveling to the first emitting portion EP1 may be blocked by the second pattern layer 155 filled in the groove portion 153. Therefore, color mixing between the light L1 emitted from the first emitting portion EP1 and the light L2 emitted from the second emitting portion EP2 can be prevented or minimized.

[0205] According to another embodiment of the present disclosure described above with reference to Figure 2 and Figure 8 , the light emitting display device may provide the same as that according to the above with reference to Figures 2 to 6The light-emitting display device according to the described embodiments of the present disclosure has the same effects, and color mixing between the light L1 emitted from the first emission part EP1 and the light L2 emitted from the second emission part EP2 can be prevented or minimized by the second pattern layer 155.

[0206] Figure 9 is another cross-sectional view taken along the Figure 2 line II-II' shown in. Figure 9 shows an embodiment achieved by modifying the bank layer in the light-emitting display device (or light-emitting display panel) described above with reference to Figures 2 to 6 . Therefore, in the following description of Figure 9 , other elements are denoted by similar reference numerals except for the bank layer and related elements, and repeated descriptions thereof are omitted. Figures 2 to 6 The description of the light-emitting display device (or light-emitting display panel) shown in may be included in the description of the light-emitting display device (or light-emitting display panel) shown in Figure 9 .

[0207] Referring to Figure 2 and Figure 9 , in a light-emitting display device (or light-emitting display panel) according to another embodiment of the present disclosure, the bank layer 170 may be formed (or configured) to cover the edge portions of each of the plurality of emission parts or the first emission part EP1 and the second emission part EP2, and the edge portions of the light-transmitting portions TP at each of the plurality of sub-pixels SP.

[0208] The bank layer 170 according to another embodiment of the present disclosure may be formed only at the edge portions of the light-transmitting portion TP in the light-transmitting portion TP, without covering the entire light-transmitting portion TP. For example, the bank layer 170 may be formed only at the edge portions of the light-transmitting portion TP except for the central portion of the light-transmitting portion TP. For example, the bank layer 170 may be formed only at the edge portions of the light-transmitting portion TP and not formed at the central portion of the light-transmitting portion TP. For example, the bank layer 170 according to another embodiment of the present disclosure may include a structure in which other portions (or the central portion of the light-transmitting portion TP) of the light-transmitting portion TP have been removed at the bank layer 170 formed to cover the entire light-transmitting portion TP described above with reference to Figures 4 to 6 . Therefore, the bank layer 170 provided at the light-transmitting portion TP may include an opening (or light-transmitting hole) overlapping or corresponding to the light-transmitting portion TP. For example, the light-transmitting portion TP may be defined by the bank layer 170 and may have a size (or area) corresponding to the opening of the bank layer 170.

[0209] According to another embodiment of the present disclosure, the bank layer 170 may be formed (or configured) to cover only the edge portions of each of the plurality of emission portions or the first emission portion EP1 and the second emission portion EP2. For example, the bank layer 170 may not be formed (or configured) at the light transmission portion TP, but may be formed (or configured) to cover only the edge portions of each of the plurality of emission portions or the first emission portion EP1 and the second emission portion EP2.

[0210] The bank layer 170 according to another embodiment of the present disclosure may include: a first bank pattern 171 formed to cover the edge portion of the first emission portion EP1 at each of the plurality of sub-pixels SP1 to SP4; a second bank pattern 172 formed to cover the edge portion of the second emission portion EP2 at each of the plurality of sub-pixels SP1 to SP4; and a third bank pattern 173 between the plurality of sub-pixels SP1 to SP4.

[0211] The first bank pattern 171 may be formed (or configured) to cover the edge portion of the first pixel electrode PE1 at the first emission portion EP1 of each of the plurality of sub-pixels SP1 to SP4. The second bank pattern 172 may be formed (or configured) to cover the edge portion of the second pixel electrode PE2 at the second emission portion EP2 of each of the plurality of sub-pixels SP1 to SP4. For example, the bank layer 170 may be formed (or configured) to cover other portions except the central portion of the light transmission portion TP, the central portion of the first emission portion EP1, and the central portion of the second emission portion EP2.

[0212] The bank layer 170 according to another embodiment of the present disclosure may be formed of an organic material such as a benzocyclobutene (BCB)-based resin, an acrylic-based resin, or a polyimide resin. For example, the bank layer 170 may be formed of a transparent material and may be a transparent bank, but is not limited thereto. For example, the bank layer 170 may be formed only at the edge portion of the light transmission portion TP and not at the entire light transmission portion TP, and thus may be formed (or configured) of a transparent material, a translucent material, or an opaque material. For example, the bank layer 170 may be a transparent bank layer or a black bank layer. For example, the bank layer 170 may be disposed in a photosensitizer including a black pigment, and in this case, the bank layer 170 may be used as a light blocking member disposed between adjacent sub-pixels SP or adjacent emission portions EP1 and EP2.

[0213] According to another embodiment of the present disclosure, the light emitting device ED above the pattern portion 150 may be formed (or configured) at other portions except the central portion of the light transmission portion TP.

[0214] The emission layer EL of the light-emitting device ED on the pattern portion 150 may be formed to surround the bank layer 170 adjacent to the light-transmitting portion TP. For example, regions of the emission layer EL corresponding (or overlapping) to the light-transmitting portion TP of each of the plurality of sub-pixels SP1 to SP4 may be removed. For example, the emission layer EL may include an opening portion (or opening region or removal region) corresponding (or overlapping) to the light-transmitting portion TP of each of the plurality of sub-pixels SP1 to SP4.

[0215] The common electrode CE of the light-emitting device ED above the pattern portion 150 may be formed to surround the emission layer EL, which surrounds the bank layer 170 adjacent to the light-transmitting portion TP. For example, one end of each of the emission layer EL and the common electrode CE of the light-emitting device ED adjacent to the light-transmitting portion TP may directly contact the first surface 150a of the pattern portion 150. For example, regions of the common electrode CE corresponding (or overlapping) to the light-transmitting portion TP of each of the plurality of sub-pixels SP1 to SP4 may be removed. For example, the common electrode CE may include an opening portion (or opening region or removal region) corresponding (or overlapping) to the light-transmitting portion TP of each of the plurality of sub-pixels SP1 to SP4.

[0216] According to another embodiment of the present disclosure, the encapsulation portion 200 may be formed above the substrate 100 to cover the light-emitting device ED. The encapsulation portion 200 may be formed above the common electrode CE of the light-emitting device ED. For example, the encapsulation portion 200 may directly contact the first surface 150a of the pattern portion 150 at the light-transmitting portion TP of each of the plurality of sub-pixels SP1 to SP4.

[0217] According to the above reference Figure 2 and Figure 9 The light-emitting display device according to another embodiment of the present disclosure described above may provide the same effects as the light-emitting display device according to the embodiment of the present disclosure described above with reference to Figures 2 to 6 and the bank layer 170 may not be provided at the light-transmitting portion TP, and thus, the light transmittance of the light-transmitting portion TP may be increased.

[0218] The bank layer 170 described above with reference to Figure 2 and Figure 9 may be similarly applied to the bank layer 170 described above with reference to Figure 7 and Figure 8 and thus, the repeated description thereof is omitted. In this case, Figure 7 and Figure 8The bank layer 170 shown in [the figure] may be configured to cover an edge portion of the second pattern layer 155 of the pattern portion 150, and a central portion of the second pattern layer 155 may be covered by the encapsulation portion 200. For example, an upper surface 155a of the second pattern layer 155 overlapping with the light transmission portion TP may be in direct contact with the encapsulation portion 200.

[0219] Figure 10 is a view showing Figure 1 another plan view of one pixel shown in [the figure], Figure 11 is a view showing Figure 10 an equivalent circuit diagram of the first sub-pixel shown in [the figure], and Figure 12 is a cross-sectional view taken along Figure 10 line III-III’ shown in [the figure]. Figure 10 A cross-sectional view of line I-I’ shown in [the figure] is shown in Figure 4 and Figure 12 an enlarged view of a portion “A” shown in [the figure] is shown in Figure 6 [the figure]. Figures 10 to 12 shows an embodiment achieved by modifying data lines and pixel circuits of each of a plurality of sub-pixels in the light-emitting display device (or light-emitting display panel) described above with reference to Figures 2 to 6 [the figure]. Therefore, in the following description of Figures 10 to 12 [the figure], elements other than data lines, pixel circuits, and related elements are denoted by similar reference numerals, and their repeated description is omitted. Figures 2 to 6 The description of the light-emitting display device (or light-emitting display panel) shown in [the figure] may be included in the description of the light-emitting display device (or light-emitting display panel) shown in Figures 10 to 12 [the figure].

[0220] Referring to Figure 4 and Figures 10 to 12 [the figure], a light-emitting display device (or light-emitting display panel) according to another embodiment of the present disclosure may be configured to implement (or display) a stereoscopic image, for example, by a light field mode (or light field type). For example, a light-emitting display device according to another embodiment of the present disclosure may display a stereoscopic image by individual light emission of each of a plurality of emission portions EP1 and EP2 disposed at each of a plurality of sub-pixels SP, and thus may implement (or display) a stereoscopic image (for example, a stereoscopic image based on a light field mode (or light field type)), or may provide a stereoscopic image to a user (or viewer).

[0221] In a light-emitting display device according to another embodiment of the present disclosure, each of the plurality of data lines DL1 to DL4 may include a plurality of sub-data lines DLa and DLb corresponding to a plurality of emission units EP1 and EP2 disposed at each of the plurality of sub-pixels SP, respectively. For example, each of the first data line DL1 to the fourth data line DL4 disposed at the plurality of sub-pixels SP may include a first sub-data line DLa and a second sub-data line DLb corresponding to the first emission unit EP1 and the second emission unit EP2, respectively. For example, the first data line DL1 disposed at the first sub-pixel SP1 may include a first sub-data line DLa and a second sub-data line DLb connected to the first emission unit EP1 and the second emission unit EP2, respectively. For example, each of the plurality of data lines or the first data line DL1 to the fourth data line DL4 may include a plurality of sub-data lines DLa and DLb equal to the number of the emission units EP1 and EP2 disposed at one sub-pixel SP.

[0222] The plurality of sub-data lines or the first sub-data line DLa and the second sub-data line DLb may be set (or configured) to be electrically disconnected from each other within one sub-pixel region SPA1 to SPA4.

[0223] According to an embodiment of the present disclosure, each of the first sub-data line DLa and the second sub-data line DLb may be set to overlap with the bank layer 170 at each of the plurality of sub-pixels SP. For example, with respect to the thickness direction Z of the substrate 100, in the first sub-pixel SP1 and the third sub-pixel SP3 (or odd sub-pixels), the first sub-data line DLa may be set to overlap with the bank layer 170 covering the edge portion of the first pixel electrode PE1 at the first emission unit EP1, and the second sub-data line DLb may be set to overlap with the bank layer 170 covering the edge portion of the second pixel electrode PE2 at the second emission unit EP2. For example, with respect to the thickness direction Z of the substrate 100, in the second sub-pixel SP2 and the fourth sub-pixel SP4 (or even sub-pixels), the first sub-data line DLa may be set to overlap with the bank layer 170 covering the edge portion of the first pixel electrode PE1 at the first emission unit EP1, and the second sub-data line DLb may be set to overlap with the bank layer 170 covering the edge portion of the second pixel electrode PE2 at the second emission unit EP2. For example, the second sub-data line DLb at the first sub-pixel SP1 and the third sub-pixel SP3 may be set to be adjacent to the first sub-data line DLa at the second sub-pixel SP2 and the fourth sub-pixel SP4.

[0224] According to another embodiment of the present disclosure, each of the plurality of sub-pixels SP may include two data lines. Accordingly, each of the plurality of sub-pixels SP may include a first data line corresponding to a first sub-data line DLa and a second data line corresponding to a second sub-data line DLb. For example, each of the plurality of sub-pixels SP may include a first sub-data line (or first data line) DLa electrically connected to a first pixel circuit PCa and a second sub-data line (or second data line) DLb electrically connected to a second pixel circuit PCb. Thus, according to Figures 10 to 12 the light-emitting display device according to another embodiment of the present disclosure shown in Figures 2 to 6 may include twice as many data lines as the data lines of the light-emitting display device according to the embodiment of the present disclosure shown in

[0225] In a light-emitting display device according to another embodiment of the present disclosure, a pixel circuit PC disposed at each of the plurality of sub-pixels SP may be configured to be separately connected to a plurality of emission units EP1 and EP2.

[0226] A pixel circuit PC according to another embodiment of the present disclosure may include a plurality of pixel circuits PCa and PCb separately connected to a plurality of emission units EP1 and EP2. For example, the pixel circuit PC may include a first pixel circuit PCa and a second pixel circuit PCb configured to be separately connected to a first emission unit EP1 and a second emission unit EP2.

[0227] According to an embodiment of the present disclosure, a pixel circuit PC disposed at each of the plurality of sub-pixels SP1 to SP4 may include: a first pixel circuit PCa including a driving TFT Tdr electrically connected to a first pixel electrode PE1 of a first emission unit EP1; and a second pixel circuit PCb including a driving TFT Tdr electrically connected to a second pixel electrode PE2 of a second emission unit EP2.

[0228] According to an embodiment of the present disclosure, each of the first pixel electrode PE1 and the second pixel electrode PE2 may be spaced apart from each other (or electrically disconnected) at an emission region EA and a circuit region CA, and may be separately connected to the first pixel circuit PCa and the second pixel circuit PCb at the circuit region CA. For example, one end of the first pixel electrode PE1 may extend into the circuit region CA and may be electrically connected to the driving thin-film transistor Tdr of the first pixel circuit PCa. One end of the second pixel electrode PE2 may extend into the circuit region CA and may be electrically connected to the driving thin-film transistor Tdr of the second pixel circuit PCb.

[0229] The first pixel circuit PCa can be electrically connected to the gate line GL, the first sub-data line DLa, electrically connected to the driving voltage line PL through the power connection line PCL, and electrically connected to the reference voltage line RL through the reference power connection line RCL. The first pixel circuit PCa can be configured to supply a first field data current corresponding to the first field data voltage supplied through the first sub-data line DLa to the first pixel electrode PE1 in response to a gate signal supplied to the corresponding gate line GL. Accordingly, the first light-emitting unit EP1 can emit light using the first field data current supplied from the first pixel circuit PCa to the first pixel electrode PE1.

[0230] The second pixel circuit PCb can be electrically connected to the gate line GL, the second sub-data line DLb, electrically connected to the driving voltage line PL through the power connection line PCL, and electrically connected to the reference voltage line RL through the reference power connection line RCL. The second pixel circuit PCb can be configured to supply a second field data current corresponding to the second field data voltage supplied through the second sub-data line DLb to the second pixel electrode PE2 in response to a gate signal supplied to the corresponding gate line GL. Accordingly, the second light-emitting unit EP2 can emit light using the second field data current supplied from the second pixel circuit PCb to the second pixel electrode PE2.

[0231] According to an embodiment of the present disclosure, each of the first pixel circuit PCa and the second pixel circuit PCb may include a first switching transistor Tsw1, a second switching transistor Tsw2, a driving transistor Tdr, and a storage capacitor Cst. Each of the first pixel circuit PCa and the second pixel circuit PCb may be the same as or substantially the same as the pixel circuit PC described above with reference to Figure 3 and Figure 4 described, and thus a repetitive description thereof is omitted.

[0232] Each of the plurality of gate lines GL may be commonly connected to the first pixel circuit PCa and the second pixel circuit PCb disposed at each of the plurality of sub-pixels or the first sub-pixel SP1 to the fourth sub-pixel SP4.

[0233] Among each of the plurality of data lines or the first data line DL1 to the fourth data line DL4, the first sub-data line DLa may be electrically connected to the first pixel circuit PCa, and may supply the first field data voltage provided from the driving IC 35 described above with reference to Figure 1 to the first pixel circuit PCa. The second sub-data line DLb may be electrically connected to the second pixel circuit PCb, and may supply the second field data voltage provided from the driving IC 35 to the second pixel circuit PCb.

[0234] According to an embodiment of the present disclosure, the first emitting unit EP1 may display a first viewing angle image VI1 corresponding to a first field data voltage, and the second emitting unit EP2 may display a second viewing angle image VI2 corresponding to a second field data voltage. For example, when the light-emitting display device is in a normal driving mode, the first viewing angle image VI1 and the second viewing angle image VI2 respectively displayed by the first emitting unit EP1 and the second emitting unit EP2 may be identical to each other, and in this case, the viewing angle may be increased or magnified. For example, when the light-emitting display device is in a light field driving mode (or a stereoscopic image display mode), the first viewing angle image VI1 and the second viewing angle image VI2 respectively displayed by the first emitting unit EP1 and the second emitting component EP2 may be different, and thus a stereoscopic image in the light field mode may be realized by each of the first viewing angle image VI1 and the second viewing angle image VI2.
