[0046] Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings.
[0047] Figure 1A and Figure 1B is a perspective view of an electronic device ED according to an embodiment of the present disclosure. Figure 1A The electronic device ED is shown in its unfolded state, and Figure 1B The folded state of the electronic device ED is shown.

For example, the substrate 110 may include a first subbase layer 111, a first intermediate barrier layer 112, a second intermediate barrier layer 113, and a second subbase layer 114. The first subbase layer 111, the first intermediate barrier layer 112, the second intermediate barrier layer 113, and the second subbase layer 114 may be sequentially stacked in the third direction DR3.
[0086] Each of the first sub-base layer 111 and the second sub-base layer 114 may include at least one of a polyimide-based resin, an acrylic-based resin, a methacrylic-based resin, a polyisoprene-based resin, a vinyl resin, an epoxy-based resin, a urethane-based resin, a cellulose-based resin, a siloxane-based resin, a polyamide-based resin, and a perylene-based resin. Meanwhile, in the present disclosure, the term "A-based resin" means a functional group including "A". A barrier layer BR may be provided on the substrate 110. The barrier layer BR may include a first sub-barrier layer BR1 provided on the substrate 110 and a second sub-barrier layer BR2 provided on the first sub-barrier layer BR1.

Each of the first intermediate barrier layer 112 and the first sub-barrier layer BR1 may include silicon oxynitride (SiON) having a refractive index of about 1.72. Each of the second intermediate barrier layer 113 and the second sub-barrier layer BR2 may include silicon oxide (SiO x ).
[0088] That is, the refractive index of the first intermediate barrier layer 112 may have a value between the refractive index of the first sub-base layer 111 and the refractive index of the second intermediate barrier layer 113. The refractive index of the first sub-barrier layer BR1 may have a value between the refractive index of the second sub-base layer 114 and the refractive index of the second sub-barrier layer BR2. As the difference in refractive index between layers in contact with each other decreases, reflection of light at the interface between layers in contact with each other may decrease.
[0089] The first sub-base layer 111 may be thicker than the second sub-base layer 114. However, the thickness of each of the first sub-base layer 111 and the second sub-base layer 114 should not be limited by the example embodiments. The first intermediate barrier layer 112 may be thinner than the second intermediate barrier layer 113, and the first sub-barrier layer BR1 may be thinner than the second sub-barrier layer BR2. However, the thickness of each of the first intermediate barrier layer 112 and the second intermediate barrier layer 113 and the first sub-barrier layer BR1 and the second sub-barrier layer BR2 should not be limited by the examples in the present disclosure.

The light blocking layer BML may be referred to as a back surface metal layer or a back surface layer.
[0091] At least one lower insulating layer BMB may be disposed between the light blocking layer BML and the barrier layer BR. The lower insulating layer BMB may include an inorganic material. For example, the lower insulating layer BMB may include at least one of silicon oxide, silicon nitride, silicon oxynitride, and amorphous silicon.
[0092] A buffer layer BF may be disposed on the lower insulating layer BMB and the barrier layer BR. The buffer layer BF may prevent metal atoms or impurities from diffusing from the substrate 110 to the first semiconductor pattern. In addition, the buffer layer BF may control a heat supply rate during a crystallization process of forming the first semiconductor pattern so that the first semiconductor pattern may be uniformly formed.
[0093] The buffer layer BF may include a first sub-buffer layer BF1 and a second sub-buffer layer BF2 disposed on the first sub-buffer layer BF1. Each of the first sub-buffer layer BF1 and the second sub-buffer layer BF2 may include at least one of silicon oxide, silicon nitride, and silicon oxynitride. For example, the first sub-buffer layer BF1 may include silicon nitride, and the second sub-buffer layer BF2 may include silicon oxide.

Each of the first light blocking layer BMLa and the second light blocking layer BMLb may be disposed to overlap the pixel circuit PC to protect the pixel circuit PC.
[0096] The first light blocking layer BMLa and the second light blocking layer BMLb may prevent a potential caused by a polarization phenomenon of the first sub base layer 111 or the second sub base layer 114 from exerting an influence on the pixel circuit PC. According to an embodiment, the second light blocking layer BMLb may be omitted.
[0097] Despite Figure 4Although not shown in the figure, in some embodiments, the first light blocking layer BMLa may be disposed below the lower insulating layer BMB. At the same time, the first light blocking layer BMLa may be disposed in the second sub-blocking layer BR2.

[0154] Fig. 6A is a plan view of the structure of a pixel according to an embodiment of the present disclosure. In more detail, Fig. 6A yes Figure 5 An enlarged plan view of area AA1-a.
[0155] Reference Fig. 6A , the first-first pixel PX1-B may have an elliptical shape with a major axis LAX1-B and a minor axis SAX1-B. Fig. 6AAs shown in , the length of the major axis LAX1-B is represented as LA1-B and the length of the minor axis SAX1-B is represented as SA1-B. The first-second pixel PX1-G may have an elliptical shape with a major axis LAX1-G and a minor axis SAX1-G. The first-third pixel PX1-R may have an elliptical shape with a major axis LAX1-R and a minor axis SAX1-R. Each of the first-first pixel PX1-B, the first-second pixel PX1-G, and the first-third pixel PX1-R may have a first eccentricity value. The first eccentricity value may be equal to or greater than about 0.8 and less than about 1. Reference will be made to Fig. 6A and Figure 6B To describe the first eccentricity.
[0156] In the present disclosure, the eccentricity K of the ellipse can be defined as In this case, Rmax represents the radius in the major axis direction of the elliptical shape, and Rmin represents the radius in the minor axis direction of the elliptical shape. The eccentricity may have a value from 0 to 1. As the eccentricity approaches 0, the elliptical shape may become more and more like a circle, and as the eccentricity approaches 1, the length difference between the major axis and the minor axis of the elliptical shape may increase. As the eccentricity of the elliptical shape approaches 1, the length of the major axis becomes longer.
[0157] When viewed in a plane, the first-first pixel PX1-B may have a size larger than each of a size of the first-second pixel PX1-G and a size of the first-third pixel PX1-R. When viewed in a plane, the size of the first-third pixel PX1-R may be larger than a size of the first-second pixel PX1-G.
[0158] The direction in which the long axis LAX1-B of the first-first pixel PX1-B extends may be the first direction DR1. The angles θLG1 and θLG2 between the extending direction of the long axis LAX1-G of the first-second pixel PX1-G and the horizontal line HL extending in the first direction DR1 may be about 40 degrees or more and about 50 degrees or less, or may be about 130 degrees or more and about 140 degrees or less. The angles θLG1 and θLG2 between the extending direction of the long axis LAX1-G of the first-second pixel PX1-G and the horizontal line HL extending in the first direction DR1 may be about 45 degrees or about 135 degrees.
[0159] The angle between the extension direction of the long axis LAX1-B of the first-first pixel PX1-B and the extension direction of the long axis LAX1-G of the first-second pixel PX1-G closest to the first-first pixel PX1-B (hereinafter, referred to as the first long axis angle) may be about 40 degrees or more and about 50 degrees or less. For example, the first long axis angle may be about 45 degrees.
[0160] The minimum distance (hereinafter, referred to as the first pixel minimum separation distance) ML1 between two pixels adjacent to each other among the first-first pixel PX1-B, the first-second pixel PX1-G, and the first-third pixel PX1-R of each of the plurality of first pixels PX1 may be about 18 μm. In the case where the first pixel minimum separation distance ML1 is less than about 18 μm and the mask is not aligned during the deposition process of each pixel, a portion of the first-first pixel PX1-B, a portion of the first-second pixel PX1-G, and a portion of the first-third pixel PX1-R may overlap with each other. In the case where the first pixel minimum separation distance ML1 is about 18 μm or more, the first-first pixel PX1-B, the first-second pixel PX1-G, and the first-third pixel PX1-R may be prevented from overlapping with each other.
[0161] If the first long axes of adjacent pixels are aligned parallel (or perpendicular, depending on the position) to each other, the first pixel minimum separation distance ML1 may be reduced. Figure 6B The long axes LAX2-B and LAX2-G are depicted (ref. Figure 6B ) are aligned parallel or perpendicular to each other. Focusing on the second-second pixel PX2-G on the upper right of the second-first pixel PX2-B near the central area of the area AA2-a, the long axes LAX2-B and LAX2-G are parallel. Focusing on the second-second pixel PX2-G on the lower right of the second-first pixel PX2-B near the central area of the area AA2-a, the long axes LAX2-B and LAX2-G are perpendicular. In this arrangement, the second pixel minimum separation distance ML2 (refer to Figure 6B ) may be short, perhaps less than the desired 18 μm. Figure 6B In the case of , the second pixel minimum separation distance ML2 can be achieved by adjusting the eccentricity of the ellipse downward so that the major axes LAX2-B and LAX2-G (refer to Figure 6B ) can be reduced. In this way, the second pixel minimum separation distance ML2 (refer to Figure 6B )and Fig. 6A The first pixel minimum separation distance ML1 is substantially the same.
[0162] That is, in the case where the angle between the extension direction of the long axis LAX1-B of the first-first pixel PX1-B and the extension direction of the long axis LAX1-G of the first-second pixel PX1-G closest to the first-first pixel PX1-B increases, the first pixel minimum separation distance ML1 is less likely to decrease. Accordingly, the first eccentricity can be increased to shorten the first pixel minimum separation distance ML1.

In the case of the fourth pixel PX4, the major axes LAX4-B and LAX4-G may be parallel (or vertical, depending on which fourth-second pixel PX4-G). Due to this parallel alignment of the major axes LAX4-B and LAX4-G, similar to the second pixel PX2 (reference Figure 6B ), the pixel minimum separation distance ML4 in the fourth pixel PX4 may be short. Therefore, the fourth eccentricity value may be reduced to increase the distance.

[0188] Reference FIG. 6A to FIG. 6D and Figure 7 , the eccentricity value of the pixel can change with the change of the major axis angle. The arrangement of the pixels when the major axis angle is zero (0) degrees can be the same as Fig. 6A The arrangement of the first pixels PX1 of the first area AA1 shown in FIG. 4 is substantially the same.

By this parallel axis arrangement, as described above, the minimum separation distance between pixels may be short. In order to extend the minimum separation distance, the eccentricity value may be adjusted downward to effectively reduce the length of the major axis. When the major axis angle is about 45 degrees or about 135 degrees, the eccentricity value may be equal to or less than about 0.6.

In this case, as described above, the minimum separation distance between pixels may be long. Therefore, by adjusting the eccentricity value to be higher without being lower than the minimum separation distance, the length of the major axis can be made longer. When the major axis angle is zero (0) degree or 90 degrees, the eccentricity value may be equal to or greater than about 0.8 and less than about 1. The average eccentricity value AEC of the overall pixel may be about 0.65.
