Description

Technical Field

[0001] The present invention relates to an electro-optical device and an electronic device. Background Art

[0002] In an electro-optical device using, for example, OLED as a light-emitting element, it is known that a coloring layer, i.e., a color filter, is provided on a sealing layer covering the light-emitting element to transmit light of a specified wavelength band in order to realize color display. In addition, OLED is the abbreviation of Organic Light Emitting Diode. In such an electro-optical device, the color of one dot is expressed by pixel units corresponding to a plurality of colors, typically a red pixel unit, a green pixel unit, and a blue pixel unit.

[0003] The areas of the light-emitting region in the red pixel portion, the light-emitting region in the green pixel portion, and the light-emitting region in the blue pixel portion are generally determined in consideration of light-emitting efficiency, visibility, life of the light-emitting layer, and the like.

[0004] For example, the technology described in Patent Document 1 describes the following structure: in four octagonal regions arranged in two rows and two columns to represent the color of one point, a red light-emitting region is allocated to one, a green light-emitting region is allocated to one, and a blue light-emitting region is allocated to the remaining two. Specifically, in the arrangement of two rows and two columns, two blue light-emitting regions are allocated to diagonal positions, and a red light-emitting region and a green light-emitting region are allocated to the remaining two.

[0005] If the distances between adjacent colored layers are different in such an arrangement, the color change becomes larger depending on the viewing angle, so in the technology described in the above-mentioned Patent Document 1, a contact area is provided at a position overlapping with the intersection of the boundary lines dividing the light-emitting areas when viewed from above. As a result, the intervals between the light-emitting areas are nearly equal, and the color change caused by the viewing angle can be suppressed.

[0006] Patent Document 1: Japanese Patent Application Publication No. 2019-117941

[0007] However, in the technology described in the above-mentioned Patent Document 1, although the color change caused by the viewing angle can be suppressed when viewed in the row or column direction, the light-emitting area and the colored layer of the same color are continuous in the oblique direction. Therefore, in the technology described in the above-mentioned Patent Document 1, there is a problem that the degree of color change is different when viewed in the row (horizontal) or column (vertical) direction and when viewed in the oblique direction. Summary of the invention

[0008] The electro-optical device of one embodiment of the present disclosure comprises, when viewed from above: a first light-emitting region that emits light of a first wavelength band; a first colored layer that transmits the light of the first wavelength band; a second light-emitting region that is arranged adjacent to the first light-emitting region in a first direction and emits light of a second wavelength band; the second colored layer that is arranged to overlap with the second light-emitting region and transmits the light of the second wavelength band; a third light-emitting region that is arranged adjacent to the second light-emitting region in a second direction and emits light of a third wavelength band; the third colored layer that is arranged to overlap with the third light-emitting region and transmits the light of the third wavelength band; and a fourth light-emitting region that is adjacent to the second light-emitting region in a second direction and emits light of a third wavelength band. The first coloring layer comprises a first coloring layer which is adjacent to the first coloring layer and a third direction which intersects the first direction and the second direction, and emits light of the second wavelength band; and a fourth coloring layer which is arranged to overlap with the fourth light-emitting area and transmits the light of the second wavelength band, the first coloring layer comprises a first area which overlaps with the first light-emitting area when viewed from above and a second area which is located between the second light-emitting area and the fourth light-emitting area when viewed from above, the third coloring layer comprises a third area which overlaps with the third light-emitting area when viewed from above and a fourth area which is located between the second light-emitting area and the fourth light-emitting area when viewed from above, and the second area at least partially overlaps with the fourth area when viewed from above.

DETAILED DESCRIPTION

[0038] Hereinafter, the electro-optical device of the embodiment of the present invention will be described with reference to the accompanying drawings. In addition, in each figure, the size and scale of each part are appropriately different from the actual size and scale. In addition, the embodiment described below is a preferred specific example, so various preferred limitations are added technically, but the scope of the present invention is not limited to these modes as long as there is no record of the main purpose of the present invention that is particularly limited in the following description.

[0039] <Electro-optical device according to the embodiment>

[0040] Figure 1 is a perspective view showing an electro-optical device 10 according to an embodiment. Figure 2 2 is a block diagram showing the electrical structure of the electro-optical device 10 .

[0041] The electro-optical device 10 is, for example, a micro display panel that displays a color image in a head-mounted display or the like. The electro-optical device 10 includes a plurality of pixel units, a driving circuit that drives the pixel units, and the like. The pixel units and the driving circuit are integrated on a semiconductor substrate. The semiconductor substrate is typically a silicon substrate, but may also be other semiconductor substrates.

[0042] The electro-optical device 10 is housed in a frame-shaped housing 192 opened in the display area 100. One end of an FPC substrate 194 is connected to the electro-optical device 10. FPC is an abbreviation for Flexible Printed Circuits. A plurality of terminals 196 for connecting to a host device (not shown) are provided at the other end of the FPC substrate 194. When the plurality of terminals 196 are connected to the host device, image data, synchronization signals, etc. are provided from the host device to the electro-optical device 10 via the FPC substrate 194.

[0043] In addition, in the figure, the X direction is the extension direction of the scanning line in the electro-optical device 10, which indicates the horizontal direction in terms of the display screen, and the Y direction is the extension direction of the data line, which indicates the vertical direction in terms of the display screen. The two-dimensional plane determined by the X direction and the Y direction is the substrate surface of the semiconductor substrate. The Z direction is perpendicular to the X direction and the Y direction, and is the emission direction of the light emitted from the light-emitting element. In addition, in this description, a top view refers to observing the semiconductor substrate from the opposite direction of the Z direction, and a cross-sectional view refers to observing the semiconductor substrate by cutting it in a direction perpendicular to the substrate surface.

[0044] like Figure 2 As shown, the electro-optical device 10 is roughly divided into a control circuit 30 , a data signal output circuit 50 , a display area 100 , and a scan line driving circuit 120 .

[0045] In the display area 100, m rows of scanning lines 12 are arranged along the X direction, and (3n) columns of data lines 14 are arranged along the Y direction and electrically insulated from the scanning lines 12. Note that m and n are integers of 2 or more.

[0046] In the display area 100, the pixel portion 110 is provided corresponding to the intersection of the scan line 12 of the m rows and the data line 14 of the (3n) columns. Therefore, the pixel portion 110 is arranged in a matrix of m rows and (3n) columns. In the arrangement of the matrix, in order to distinguish the rows, sometimes the 1st, 2nd, 3rd, ..., (m-1), and mth rows are referred to from top to bottom in the figure. Similarly, in order to distinguish the columns of the matrix, sometimes the 1st, 2nd, 3rd, ..., (3n-2), (3n-1), and (3n)th columns are referred to from left to right in the figure.

[0047] In order to generally describe the scanning line 12, an integer i of 1 to m is used. Similarly, in order to generally describe the data line 14, an integer j of 1 to (3n) is used.

[0048] The control circuit 30 controls each unit based on the video data Vid and the synchronization signal Sync supplied from an upper host device (not shown). Specifically, the control circuit 30 generates various control signals to control each unit.

[0049] The video data Vid specifies the grayscale of pixels in the image to be displayed using, for example, 8 bits. The synchronization signal Sync includes a vertical synchronization signal that indicates the start of vertical scanning of the video data Vid, a horizontal synchronization signal that indicates the start of horizontal scanning, and a dot clock signal that indicates the timing of one pixel of the video data.

[0050] In the present embodiment, pixels of an image to be displayed correspond one-to-one to the pixel portions 110 in the display region 100 .

[0051] The characteristics of brightness in the grayscale indicated by the image data Vid provided from the host device are not necessarily consistent with the characteristics of brightness in the OLED included in the pixel unit 110. Therefore, in order to make the OLED emit light at a brightness corresponding to the grayscale indicated by the image data Vid, the control circuit 30 up-converts 8 bits of the image data Vid into 10 bits, for example, and outputs the image data Vdata. Therefore, the 10-bit image data Vdata is data corresponding to the grayscale specified by the image data Vid.

[0052] In the up-conversion, a lookup table is used which stores in advance the correspondence between 8 bits of the input video data Vid and 10 bits of the output video data Vdata.

[0053] The scan line driving circuit 120 is a circuit for driving the pixel units 110 arranged in m rows (3n) columns for each row according to the control of the control circuit 30. For example, the scan line driving circuit 120 sequentially supplies scan signals / Gwr(1), / Gwr(2), ..., / Gwr(m-1), / Gwr(m) to the scan lines 12 of the 1st, 2nd, 3rd, ..., (m-1), and mth rows. Generally speaking, the scan signal supplied to the scan line 12 of the i-th row is denoted as / Gwr(i).

[0054] The data signal output circuit 50 is a circuit that outputs a data signal to the pixel unit 110 located in the row selected by the scan line driving circuit 120 via the data line 14 according to the control of the control circuit 30. The data signal is a voltage signal obtained by converting the 10-bit image data Vdata into an analog signal. That is, the data signal output circuit 50 converts the image data Vdata of one row corresponding to the pixel unit 110 of the 1st to (3n)th columns in the selected row into analog signals, and outputs them to the data lines 14 of the 1st to (3n)th columns in this order.

[0055] In the figure, the data signals output to the data lines 14 of the 1st, 2nd, 3rd, ..., (3n-2), (3n-1), (3n) columns are marked as Vd(1), Vd(2), Vd(3), ..., Vd(3n-2), Vd(3n-1), Vd(3n) in sequence. Generally speaking, the potential of the data line 14 in the jth column is marked as Vd(j).

[0056] In the display region 100, the pixel portion 110 is as shown in FIG. Figure 2 As shown, in terms of electricity, the pixel units 110 of R, the pixel units 110 of B, and the pixel units 110 of G are arranged along the X direction, and the pixel units 110 of the same color are arranged along the Y direction. Therefore, if we focus on any column of data lines 14, there is a pixel unit 110 of the same color. In addition, one color is expressed by additive color mixing of the pixel units 110 of RBG adjacent to each other in the X direction. Therefore, the pixel unit 110 should strictly be called a sub-pixel unit, but for the sake of convenience, it is expressed as a pixel unit.

[0057] in addition, Figure 2 The configuration of the pixel portion 110 shown is merely an electrical configuration. In reality, as described later, Figure 5 As shown in FIG. 1 , a light-emitting region is arranged in a pixel portion of each color.

[0058] Figure 3 1 is a diagram showing the electrical structure of the pixel unit 110 in the electro-optical device 10. The pixel units 110 arranged in m rows (3n) columns are electrically identical to each other. Therefore, the pixel unit 110 will be described using a pixel unit 110 corresponding to the i-th row and j-th column as a representative.

[0059] As shown in the figure, from an electrical point of view, the pixel portion 110 includes P-channel MOS transistors 121 and 122 , an OLED 130 , and a capacitor 140 .

[0060] In the description of the pixel unit 110, "from an electrical point of view" is used to describe the multiple elements constituting the pixel unit 110 and the connection relationship between the multiple elements. The pixel unit 110 includes elements that do not contribute to the electrical connection relationship from a mechanical or physical point of view, so this expression is used.

[0061] The OLED 130 is an example of a light-emitting element, and a light-emitting layer 132 is sandwiched between a pixel electrode 131 and a common electrode 133. The pixel electrode 131 functions as an anode, and the common electrode 133 functions as a cathode. In addition, the details of the OLED 130 will be described later. When a current flows from the anode to the cathode, holes injected from the anode and electrons injected from the cathode recombine in the light-emitting layer 132 to generate excitons, thereby generating white light.

[0062] The white light produced by Figure 3 The reflective electrode omitted in the optical resonator and the common electrode 133 as a semi-reflective and semi-transmissive layer resonate in the optical resonator, and emits light at a resonant wavelength set corresponding to any one of red, green, and blue. A color filter corresponding to the color is provided on the emission side of the light emitted from the optical resonator. Therefore, the emitted light from the OLED 130 is colored by the optical resonator and the color filter, and is visually recognized by the observer.

[0063] In the transistor 121 of the pixel portion 110 in the i row and j column, the gate node g is connected to the drain node of the transistor 122 , the source node is connected to the supply line 116 of the voltage Vel, and the drain node is connected to the pixel electrode 131 which is the anode of the OLED 130 .

[0064] In the transistor 122 of the pixel portion 110 in the i-th row and the j-th column, the gate node is connected to the scanning line 12 of the i-th row, and the source node is connected to the data line 14 of the j-th column. The common electrode 133 functioning as the cathode of the OLED 130 is connected to the power supply line 118 of the voltage Vct. In addition, since the electro-optical device 10 is formed on a silicon substrate, the substrate potential of the transistors 121 and 122 is, for example, a potential equivalent to the voltage Vel.

[0065] Figure 3 The pixel unit 110 shown is the same for each color of red, green and blue from an electrical point of view, so it is generally described without specifying the color, but it is different for each color from a structural point of view. Therefore, when describing it by color, it is marked as pixel unit 110R, 110G, 110B. Similarly, regarding OLED 130 and pixel electrode 131, when describing it by color, it is also marked as OLED 130R, 130G, 130B, and marked as pixel electrode 131R, 131G, 131B.

[0066] Figure 4 It is a timing chart for explaining the operation of the electro-optical device 10 .

[0067] In the electro-optical device 10, the m rows of scanning lines 12 are scanned row by row in the order of the 1st, 2nd, 3rd, ..., mth rows during a frame (V). Specifically, as shown in the figure, the scanning signals / Gwr(1), / Gwr(2), ..., / Gwr(m-1), / Gwr(m) are exclusively turned into L level in sequence during each horizontal scanning period (H) by the scanning line driving circuit 120.

[0068] In addition, in the present embodiment, the periods during which adjacent scanning signals in the scanning signals / Gwr(1) to / Gwr(m) are at L level are isolated in time. Specifically, after the scanning signal / Gwr(i-1) changes from L level to H level, the next scanning signal / Gwr(i) becomes L level after an interval period. This period corresponds to the horizontal retrace period.

[0069] In this description, the period of one frame (V) refers to the period required to display one frame of an image specified by the image data Vid. If the length of the period of one frame (V) is the same as the vertical synchronization period, for example, if the frequency of the vertical synchronization signal included in the synchronization signal Sync is 60 Hz, the length of the period of one frame (V) is 16.7 milliseconds, which is equivalent to one cycle of the vertical synchronization signal. In addition, the horizontal scanning period (H) is the interval of time during which the scanning signals / Gwr(1) to / Gwr(m) successively become L level, but for convenience in the figure, the start timing of the horizontal scanning period (H) is set to the approximate center of the horizontal retrace period.

[0070] When one of the scanning signals / Gwr(1) to / Gwr(m), for example, the scanning signal / Gwr(i) supplied to the scanning line 12 of the i-th row, becomes L level, the transistor 122 becomes conductive in the pixel portion 110 of the i-th row and the j-th column with respect to the j-th column. Therefore, the gate node g of the transistor 121 in the pixel portion 110 becomes electrically connected to the data line 14 of the j-th column.

[0071] In this description, the “on state” of a transistor refers to a state where the source node and the drain node of the transistor are electrically closed and low impedance is achieved. In addition, the “off state” of a transistor refers to a state where the source node and the drain node are electrically opened and high impedance is achieved.

[0072] In addition, in this description, "electrically connected" or simply "connected" refers to a state where two or more elements are directly or indirectly connected or coupled. "Non-electrically connected" or simply "non-connected" refers to a state where two or more elements are not directly or indirectly connected or coupled.

[0073] During the horizontal scanning period (H) when the scanning signal / Gwr(i) is at the L level, the data signal output circuit 50 converts the grayscale level of the pixels in the i-row 1 column to the i-row n column indicated by the image data Vdata into analog potentials Vd(1) to Vd(n), and outputs them as data signals to the data lines 14 of the 1st to nth columns. For the jth column, the data signal output circuit 50 converts the grayscale level d(i, j) of the pixels in the i-row j column into an analog signal potential Vd(j), and outputs it as a data signal to the data line 14 of the jth column.

[0074] In addition, during the horizontal scanning period (H) when the scanning signal / Gwr(i-1) of the previous row of the scanning signal / Gwr(i) becomes the L level, the data signal output circuit 50 converts the grayscale level d(i-1, j) of the pixel in the (i-1) row and j column into the potential Vd(j) of the analog signal, and outputs it as a data signal to the data line 14 of the j column.

[0075] The data signal of the potential Vd(j) is applied to the gate node g of the transistor 121 in the pixel portion 110 of the i row and j column via the data line 14 of the j column, and the potential Vd(j) is held by the capacitor 140. Therefore, the transistor 121 allows a current corresponding to the voltage between the gate node and the source node to flow to the OLED 130.

[0076] Even if the scanning signal Gwr(i) becomes H level, the transistor 122 becomes off, and the potential Vd(j) is also held by the capacitor 140, so that current continues to flow through the OLED 130. Therefore, in the pixel portion 110 of the i-th row and j-th column, until the transistor 122 is turned on again after a period of one frame (V) and the voltage of the data signal is applied again, the OLED 130 continues to emit light at a brightness corresponding to the voltage held by the capacitor 140, that is, the grayscale.

[0077] In addition, although the pixel unit 110 in the i-th row and the j-th column is described here, the OLED 130 in the pixel unit 110 other than the i-th row and the j-th column also emits light at the brightness indicated by the image data Vdata.

[0078] Furthermore, the OLEDs 130 of the pixel units 110 other than the i-th row also emit light at the brightness indicated by the video data Vdata as the scanning signals / Gwr(1) to / Gwr(m) are sequentially turned to the L level.

[0079] Therefore, in the electro-optical device 10 , during one frame (V), the OLEDs 130 in all the pixel units 110 from the 1st row and the 1st column to the mth row and the nth column emit light at the brightness indicated by the video data Vdata, and an image of one frame is displayed.

[0080] Figure 5 is a plan view showing the arrangement of the pixel unit 110 in the display region 100 of the electro-optical device. Figure 6 It is a plan view showing the shape of a pixel electrode. Figure 7 is a top view showing the configuration of the coloring layer. Figure 5 , Figure 6 as well as Figure 7 In the figure, the E direction refers to the direction obtained by rotating the X direction counterclockwise by 45 degrees, and the F direction refers to the direction obtained by rotating the E direction counterclockwise by 90 degrees.

[0081] In the display area 100, the color of one point is determined based on the Figure 5 Specifically, in the frame Dp, the light-emitting regions R, G1, G2, and B are arranged in 2 rows and 2 columns, wherein the light-emitting regions R and B are arranged at one of the diagonals of the 2 rows and 2 columns, and the light-emitting regions G1 and G2 are arranged at the other diagonal.

[0082] The luminous area R is Figure 6 The pixel electrode 131R shown is a region in contact with the light emitting layer 132. The light emitting regions G1 and G2 are regions in contact with the light emitting layer 132 in the pixel electrode 131G. The light emitting region B is a region in contact with the light emitting layer 132 in the pixel electrode 131B.

[0083] The light emitting regions R, G1, G2, and B are defined in sequence by openings Ap_R, Ap_G1, Ap_G2, and Ap_B. The openings Ap_R, Ap_G1, Ap_G2, and Ap_B are formed by patterning a pixel isolation layer provided to cover the pixel electrodes 131R, 131G, and 131B as described later.

[0084] The green light-emitting areas are two areas, G1 and G2, which are wider than one area of ​​the light-emitting area R or the light-emitting area B. This is because green has the highest visibility among red, green, and blue, and thus the life of green is ensured.

[0085] exist Figure 6 In the pixel electrode 131R, when viewed from above, the pixel electrode 131R has a shape that is a combination of an octagon and a rectangle. Specifically, one side of the rectangular region in the pixel electrode 131R is approximately the same length as one side of the octagonal region, and the rectangle is located in a direction opposite to the E direction relative to the octagon. An octagonal opening Ap_R that is smaller than the octagon is provided in the octagonal region in such a pixel electrode 131R, and a contact region Ct_Px_R is provided in the rectangular region. The contact region Ct_Px_R is a connection region with the lower wiring in the pixel electrode 131R, and the lower wiring is also electrically connected to the drain node of the transistor 121 in the pixel portion 110R via a plurality of elements.

[0086] The pixel electrode 131G has a shape in which two pixel electrodes 131G are continuous and integrated in the direction E when viewed from above. In such a pixel electrode 131G, an opening Ap_G1 having an octagonal shape smaller than the octagon is provided in an octagonal region in the direction opposite to the direction E of the two octagons. In the pixel electrode 131G, an opening Ap_G2 having an octagonal shape smaller than the octagon is provided in an octagonal region in the direction E of the two octagons.

[0087] In the pixel electrode 131G, a contact region Ct_Px_G is provided in a rectangular region in the direction opposite to the E direction with respect to the opening Ap_G1 , and a dummy contact region Ct_Dm is provided in a rectangular region between the openings Ap_G1 and Ap_G2 .

[0088] The contact region Ct_Px_G is a region of the pixel electrode 131G connected to the lower wiring, which is also electrically connected to the drain node of the transistor 121 in the pixel portion 110G via a plurality of elements. The dummy contact region Ct_Dm is a region of the pixel electrode 131G not connected to the lower wiring.

[0089] The pixel electrode 131B has a shape substantially the same as the pixel electrode 131R when viewed from above. An octagonal opening Ap_B smaller than the octagon is provided in the octagonal region of the pixel electrode 131B, and a contact region Ct_Px_B is provided in the rectangular region. The contact region Ct_Px_B is a connection region with the lower wiring in the pixel electrode 131B, and the lower wiring is also electrically connected to the drain node of the transistor 121 in the pixel portion 110B via a plurality of elements.

[0090] Figure 7 It is a top view showing the arrangement of the coloring layers. Figure 8 is a top view showing the shape of the colored layer, Fig. 9 It is a diagram for explaining the overlapping of coloring layers.

[0091] like Figure 7 as well as Figure 8 As shown, the green coloring layer Cf_G is octagonal in a plan view and is provided to cover the light-emitting regions G1 and G2 respectively. The blue coloring layer Cf_B is provided to cover the light-emitting region B and to correspond to the region between the light-emitting regions G1 and G2 adjacent along the E direction and the F direction. Similarly, the red coloring layer Cf_R is provided to cover the light-emitting region R and to correspond to the region between the light-emitting regions G1 and G2 adjacent along the E direction and the F direction.

[0092] like Figure 8 As shown, the color layer Cf_B includes an octagonal region Ba covering the light-emitting region B and rectangular regions Bb1, Bb2, Bb3, and Bb4 in the region between the light-emitting regions G1 and G2 in a plan view.

[0093] Region Bb1 among the four regions Bb1, Bb2, Bb3 and Bb4 is a rectangle that contacts the octagonal region Ba in the direction opposite to the F direction when viewed from above, and is arranged between the colored layer Cf_G adjacent to the region Ba in the X direction (corresponding to the light-emitting region G2) and the colored layer Cf_G adjacent to the region Ba in the Y direction (corresponding to the light-emitting region G1).

[0094] Region Bb2 is a rectangle that contacts region Ba in the opposite direction of the E direction when viewed from above, and is arranged between the colored layer Cf_G adjacent to region Ba in the Y direction (corresponding to the light-emitting region G1) and the colored layer Cf_G adjacent to region Ba in the opposite direction of the X direction (corresponding to the light-emitting region G2).

[0095] Region Bb3 is a rectangle that contacts region Ba in the F direction when viewed from above, and is arranged between the colored layer Cf_G (corresponding to the light-emitting region G2) adjacent to region Ba in the opposite direction of the X direction and the colored layer Cf_G (corresponding to the light-emitting region G1) adjacent to region Ba in the opposite direction of the Y direction.

[0096] Region Bb4 is a rectangle that contacts region Ba in the E direction when viewed from above, and is arranged between the coloring layer Cf_G (corresponding to the light-emitting region G1) adjacent to region Ba in the opposite direction of the Y direction and the coloring layer Cf_G (corresponding to the light-emitting region G2) adjacent to region Ba in the X direction.

[0097] The colored layer Cf_R includes, in a plan view, an octagonal region Ra covering the light-emitting region R and rectangular regions Rb1 , Rb2 , Rb3 , and Rb4 in the region between the light-emitting regions G1 and G2 .

[0098] Among the four regions Rb1, Rb2, Rb3 and Rb4, region Rb1 is a rectangle that contacts the octagonal region Ra in the opposite direction of the F direction when viewed from above, and is arranged between the coloring layer Cf_G adjacent to the region Ra in the X direction (corresponding to the light-emitting region G1) and the coloring layer Cf_G adjacent to the region Ra in the Y direction (corresponding to the light-emitting region G2).

[0099] Region Rb2 is a rectangle that is in contact with region Ra in the opposite direction of the E direction when viewed from above, and is arranged between the colored layer Cf_G (corresponding to the light-emitting region G2) adjacent to region Ra in the Y direction and the colored layer Cf_G (corresponding to the light-emitting region G1) adjacent to region Ra in the opposite direction of the X direction.

[0100] Region Rb3 is a rectangle that contacts region Ra in the F direction when viewed from above, and is arranged between the colored layer Cf_G (corresponding to the light-emitting region G1) adjacent to region Ra in the opposite direction of the X direction and the colored layer Cf_G (corresponding to the light-emitting region G2) adjacent to region Ra in the opposite direction of the Y direction.

[0101] Region Rb4 is a rectangle that contacts region Ra in the E direction when viewed from above, and is arranged between the coloring layer Cf_G (corresponding to the light-emitting region G2) adjacent to region Ra in the opposite direction of the Y direction and the coloring layer Cf_G (corresponding to the light-emitting region G1) adjacent to region Ra in the X direction.

[0102] The region Rb3 of the color layer Cf_R overlaps with the region Bb1 of the color layer Cf_B constituting the same point.

[0103] Region Rb4 of the coloring layer Cf_R overlaps with region Bb2 of the coloring layer Cf_B constituting another dot.

Figure 3 The point adjacent to F in the opposite direction, that is, located diagonally above the left.

[0106] Next, the cross-sectional structure of the main parts of the electro-optical device 10 will be described.

[0107] Fig.10 is a cross-sectional view of a main part of a pixel unit 110R in the electro-optical device 10. Figure 6 A cross-sectional view of a region including the light emitting region R and the contact region Ct_Px_R when cut along the E direction.

[0108] The contact electrode 61R is formed on the substrate 60 and is electrically connected to a circuit layer (not shown) via a contact hole (not shown). The circuit layer includes the scanning line 12 , the data line 14 , and the transistors 121 and 122 .

[0109] The reflective electrode 62R is stacked on the contact electrode 61R to reflect light incident from the opposite direction of the Z direction in the Z direction. As the reflective electrode 62R, for example, a conductive layer formed by stacking an aluminum and copper alloy (AlCu) film on a titanium (Ti) film is used. The contact electrode 61R and the reflective electrode 62R are electrodes provided corresponding to the pixel portion 110R among electrodes in which the conductive layer is individually patterned into an island shape in a plan view for each pixel portion 110R, 110G, and 110B.

[0110] In addition, a gap 62Ct is generated by the island-shaped patterning.

[0111] The reflection-enhancing layer 63 is a layer for improving the reflection characteristics of the reflection electrode 62R. The reflection-enhancing layer 63 has insulation and light-transmitting properties, and is provided to cover the reflection electrode 62R. As the reflection-enhancing layer 63, for example, silicon oxide is used.

[0112] The first insulating layer 64 covers the reflection-enhancing layer 63 and is provided along the gap 62Ct. Therefore, the first insulating layer 64 has a concave portion 64a near the gap 62Ct. The buried insulating layer 66 is provided in a manner to fill the concave portion 64a. The second insulating layer 65 is stacked on the first insulating layer 64 and the buried insulating layer 66. For example, silicon nitride (SiN) is used as the first insulating layer 64 and the second insulating layer 65, and for example, silicon oxide is used as the buried insulating layer 66.

[0113] The protection layer 72 is an insulating film stacked on the second insulating layer 65 , and is made of, for example, silicon oxide.

[0114] The reflection-enhancing layer 63 , the first insulating layer 64 , the second insulating layer 65 , and the protective layer 72 have openings in the contact region Ct_Px_R.

[0115] The relay electrode 71R is formed by patterning a conductive layer along the opening and stacked on the reflective electrode 62R and the protective layer 72. The relay electrode 71R has a recessed portion along the opening. As the conductive layer constituting the relay electrode 71R, titanium nitride (TiN) is used, for example.

[0116] The first optical adjustment layer 67 and the second optical adjustment layer 68 are insulating layers for adjusting the optical distance in the optical resonator and have light transmittance. For example, silicon oxide is used as the first optical adjustment layer 67 and the second optical adjustment layer 68. The first optical adjustment layer 67 and the second optical adjustment layer 68 have a hole in the region CtR in the contact region Ct_Px_R.

[0117] The pixel electrode 131R is formed by patterning a light-transmitting conductive layer. The pixel electrode 131R is stacked on the second optical adjustment layer 68 or the relay electrode 71R, and is stacked on the second insulating layer 65 in the region CtR where the first optical adjustment layer 67 and the second optical adjustment layer 68 have openings. The pixel electrode 131R is patterned as follows when viewed from above: Figure 6 The pixel electrode 131R is stacked along the opening of the region CtR, and thus has a recessed portion corresponding to the region CtR. As the conductive layer constituting the pixel electrode 131R, for example, ITO (Indium Tin Oxide) is used.

[0118] The pixel isolation layer 134 is stacked on the second optical adjustment layer 68, the second insulating layer 65, or the pixel electrode 131R, and is an insulating film provided to cover the peripheral portion of the pixel electrode 131R. Figure 5 The pixel isolation layer 134 is formed of, for example, silicon oxide.

[0119] The light emitting layer 132 is stacked on the pixel electrode 131R or the pixel isolation layer 134. Although not particularly shown, the light emitting layer 132 includes a hole injection layer, an organic light emitting layer, and an electron transport layer, and is common to all of the pixel portions 110R, 110G, and 110B.

[0120] The common electrode 133 is a conductive layer having light transmittance and reflectivity. The common electrode 133 is provided so as to cover the light emitting layer 132 and is common to all the pixel units 110R, 110G, and 110B. For example, an alloy of Mg and Ag is used as the common electrode 133.

[0121] The light emitting layer 132 emits white light when holes are supplied from a region of the pixel electrode 131R that is not covered by the pixel isolation layer 134 , that is, a region that is in contact with the pixel electrode 131R and defined by the opening Ap_R.

[0122] In the portion corresponding to the light emitting region R in a plan view, an optical resonator is formed by the reflective electrode 62R and the common electrode 133 in a cross-sectional view, and the optical distance LR between the reflective electrode 62R and the common electrode 133 is adjusted by the film thickness of the first optical adjustment layer 67 and the second optical adjustment layer 68. In addition, strictly speaking, the optical distance refers to a value obtained by multiplying the distance between the reflective electrode 62R and the common electrode 133 by the refractive index of the medium between the reflective electrode 62R and the common electrode 133, but it is illustrated here only as a physical distance.

[0123] In the portion corresponding to the light emitting region R, the white light emitted from the light emitting layer 132 is repeatedly reflected between the reflective electrode 62R and the common electrode 133, and the intensity of the light of the wavelength corresponding to the optical distance LR is enhanced. In this embodiment, as an example, the intensity of the light of the wavelength of 610nm is enhanced in the pixel portion 110R. The enhanced light passes through the common electrode 133, and is emitted as red light in the Z direction, etc. through the coloring layer Cf_R.

[0124] In this way, light including a red wavelength band is emitted from the light emitting region R in the Z direction and the like.

[0125] The first sealing layer 81 is a light-transmitting insulating layer, and is provided so as to cover the common electrode 133 .

[0126] The planarization layer 82 is a light-transmitting insulating layer, and is provided so as to cover the first sealing layer 81 so as to eliminate the step and make the observation surface flat. As the planarization layer 82, for example, an organic material such as epoxy resin is used.

[0127] The second sealing layer 83 is a light-transmitting insulating layer, and is provided so as to cover the planarization layer 82. The first sealing layer 81 and the second sealing layer 83 are provided to prevent moisture, oxygen, etc. from entering the light-emitting layer 132. As the first sealing layer 81 and the second sealing layer 83, for example, silicon oxynitride (SiON) is used.

[0128] In the light emitting region R of the pixel unit 110R, the coloring layer Cf_R covers the second sealing layer 83 and has a shape similar to that of the second sealing layer 83 in a plan view. Figure 7 as well as Figure 8 The shape shown is set at Fig. 9 The coloring layer Cf_R is provided by patterning a photosensitive resin containing a pigment that selectively transmits red light using a photolithography technique. Thus, the coloring layer Cf_R has a function of transmitting red light. Red light refers to light in a wavelength band containing red. In this embodiment, the wavelength band of red refers to a wavelength of 580 nm or more and 700 nm or less.

[0129] In the pixel portion 110R, the contact region Ct_Px_R is included in the regions Bb4 and Rb2 in a plan view. Therefore, in the region including the contact region Ct_Px_R, the red coloring layer Cf_R is overlapped with the blue coloring layer Cf_B. In addition, a protective glass or the like is provided via an adhesive to cover the coloring layers Cf_R and Cf_B, but this is omitted in the present application.

[0130] Fig.11 is a cross-sectional view of a main part of a pixel unit 110G of the electro-optical device 10. Figure 6A cross-sectional view of a region including the light emitting region G2 , the dummy contact region Ct_Dm, the light emitting region G1 , and the contact region Ct_Px_G when the region is cut along the E direction.

[0131] First, the light emitting regions G1 and G2 in the pixel unit 110G are described. Fig.10 The light emitting regions R shown are different in that, first, the first optical adjustment layer 67 is not provided in the light emitting regions G1 and G2.

[0132] Specifically, in the portion corresponding to the light emitting region R, the first optical adjustment layer 67 and the second optical adjustment layer 68 are provided between the reflective electrode 62R and the pixel electrode 131R. In contrast, in the portions corresponding to the light emitting regions G1 and G2, the second optical adjustment layer 68 is provided between the reflective electrode 62G and the pixel electrode 131G, but the first optical adjustment layer 67 is not provided.

[0133] Therefore, in the portions corresponding to the light emitting regions G1 and G2 , the optical distance LG between the reflective electrode 62G and the common electrode 133 is shorter than the optical distance LR in the portion corresponding to the light emitting region R by an amount corresponding to the absence of the first optical adjustment layer 67 .

[0134] In addition, as a difference between the light-emitting regions G1 and G2 and the light-emitting region R, the pixel electrode 131G is shaped like a pixel electrode 131G in a plan view. Figure 6 The pixel electrode 131G is stacked on the second optical adjustment layer 68 in the light emitting regions G1 and G2 , which is the same as the light emitting region R.

[0135] The contact electrode 61R, the reflective electrode 62R, and the relay electrode 71R in the pixel portion 110R are provided in this order as the contact electrode 61G, the reflective electrode 62G, and the relay electrode 71G in the pixel portion 110G.

[0136] In the portion corresponding to the light-emitting regions G1 and G2, the white light emitted from the light-emitting layer 132 is repeatedly reflected between the reflective electrode 62G and the common electrode 133, and the intensity of the light of the wavelength corresponding to the optical distance LG is enhanced. In this embodiment, as an example, the intensity of the light of the wavelength of 540nm is enhanced in the pixel portion 110G. The enhanced light passes through the common electrode 133 and is emitted as green light in the Z direction, etc., via the coloring layer Cf_G.

[0137] In this way, light including a green wavelength band is emitted from the light emitting regions G1 and G2 in the Z direction and the like when viewed from above.

[0138] Next, the contact region Ct_Px_G in the pixel portion 110G will be described.

[0139] In the contact region Ct_Px_G, the reflection-enhancing layer 63, the first insulating layer 64, the second insulating layer 65, and the protective layer 72 have openings, and the relay electrode 71G is provided along the openings and is stacked on the reflective electrode 62G and the protective layer 72. In the pixel portion 110G, the first optical adjustment layer 67 is not provided, and therefore, in the region CtG, only the second optical adjustment layer 68 has openings.

[0140] Through such a contact region Ct_Px_G, the pixel electrode 131G is electrically connected to a circuit layer (not shown) via the relay electrode 71G, the reflective electrode 62G, and the contact electrode 61G in sequence.

[0141] In the dummy contact region Ct_Dm, a protective layer 72 and a dummy relay electrode 71D are sequentially provided on the surface in the Z direction of the second insulating layer 65. The dummy relay electrode 71D is formed by patterning the same layer as the relay electrodes 71R, 71G, and 71B.

[0142] In the dummy contact region Ct_Dm, the first optical adjustment layer 67 is provided so as to cover the protective layer 72 and the dummy relay electrode 71D.

[0143] In the dummy contact region Ct_Dm, the first optical adjustment layer 67 and the second optical adjustment layer 68 exist between the pixel electrode 131G and the dummy relay electrode 71D, and the protective layer 72 and the second insulating layer 65 exist between the dummy relay electrode 71D and the reflective electrode 62G.

[0144] Therefore, the pixel electrode 131G and the dummy relay electrode 71D are not electrically connected, and the dummy relay electrode 71D and the reflective electrode 62G are not electrically connected either.

[0145] In this embodiment, in the dummy contact region Ct_Dm, the pixel electrode 131G is not electrically connected to the reflective electrode 62G (the drain node of the transistor 121). Therefore, in the dummy contact region Ct_Dm, the pixel electrode 131G does not contribute to the electrical connection with the reflective electrode 62G. For this reason, it is called a dummy contact region.

[0146] In the light emitting regions G1 and G2 of the pixel unit 110G, the coloring layer Cf_G covers the second sealing layer 83 and has a shape similar to that of the second sealing layer 83 in a plan view. Figure 7 as well as Figure 8 The shape shown is set at Fig. 9 The coloring layer Cf_G is provided by patterning a photosensitive resin containing a pigment that selectively transmits green light using a photolithography technique. Thus, the coloring layer Cf_G has a function of transmitting green light. Green light refers to light containing a wavelength band of green. In this embodiment, the wavelength band of green refers to a wavelength of 500 nm or more and 580 nm or less.

[0147] In the pixel portion 110G, the contact region Ct_Px_G is included in the regions Bb3 and Rb1 in a plan view. Therefore, in the region including the contact region Ct_Px_G, the red colored layer Cf_R is provided to overlap the blue colored layer Cf_B.

[0148] In the pixel portion 110G, the dummy contact region Ct_Dm is included in the regions Bb1 and Rb3 in a plan view. Therefore, in the dummy contact region Ct_Dm, the red colored layer Cf_R is provided to overlap the blue colored layer Cf_B.

[0149] Fig.12 is a cross-sectional view of a main part of a pixel unit 110B of the electro-optical device 10. Figure 6 A cross-sectional view of a region including the light emitting region B and the contact region Ct_Px_B when cut along the E direction.

[0150] First, the light emitting region B in the pixel portion 110B will be described. Fig.11 The light emitting region G1 or G2 shown is different in that, first, the light emitting region B is not provided with the second optical adjustment layer 68 .

[0151] Therefore, in the portion corresponding to the light emitting region B, the optical distance LB between the reflective electrode 62B and the common electrode 133 is shorter than the optical distance LG in the portion corresponding to the light emitting region G1 or G2 by the absence of the second optical adjustment layer 68 .

[0152] Therefore, the optical distances LR, LG, and LB in the optical resonator satisfy

[0153] LR>LG>LB

[0154] relationship.

[0155] In the pixel portion 110B, the pixel electrode 131B is patterned as follows when viewed from above. Figure 6 The pixel electrode 131B is stacked on the second insulating layer 65 in the light emitting region B, which is the same as the light emitting regions R, G1, and G2.

[0156] The contact electrode 61R, the reflective electrode 62R, and the relay electrode 71R in the pixel portion 110R are provided in this order as the contact electrode 61B, the reflective electrode 62B, and the relay electrode 71B in the pixel portion 110B.

[0157] In the contact region Ct_Px_B, the reflection-enhancing layer 63, the first insulating layer 64, the second insulating layer 65, and the protective layer 72 have openings, and the relay electrode 71B is provided along the openings and is stacked on the reflective electrode 62B and the protective layer 72. In the pixel portion 110B, the first optical adjustment layer 67 and the second optical adjustment layer 68 are not provided, so no concave portion such as the regions CtR and Ct_G is provided. Through such a contact region Ct_Px_B, the pixel electrode 131B is electrically connected to a circuit layer (not shown) in sequence via the relay electrode 71B, the reflective electrode 62B, and the contact electrode 61B.

[0158] In the light-emitting region B of the pixel portion 110B, the coloring layer Cf_B is provided in a manner covering the second sealing layer 83. The coloring layer Cf_B is provided by patterning a photosensitive resin containing a pigment that allows blue light to pass through using a photolithography technique. Thus, the coloring layer Cf_B has a function of allowing blue light to pass through. Blue light refers to light containing a wavelength band of blue. In this embodiment, the wavelength band of blue is greater than 400 nm and less than 500 nm.

[0159] In the pixel portion 110B, the contact region Ct_Px_B is included in the regions Bb2 and Rb4 in a plan view. Therefore, in the region including the contact region Ct_Px_B, the red colored layer Cf_R is provided to overlap the blue colored layer Cf_B.

[0160] In the portion corresponding to the light emitting region B, the white light emitted from the light emitting layer 132 is repeatedly reflected between the reflective electrode 62B and the common electrode 133, and the intensity of the light having a wavelength corresponding to the optical distance LB is enhanced. In this embodiment, as an example, the intensity of the light having a wavelength of 470 nm is enhanced in the pixel portion 110B. The enhanced light passes through the common electrode 133 and is emitted as blue light in the Z direction or the like via the coloring layer Cf_B.

[0161] In this way, light including a blue wavelength band is emitted from the light emitting region B in the Z direction or the like when viewed from above.

[0162] Fig.13 is a cross-sectional view of the main parts of the electro-optical device 10. Figure 6 A cross-sectional view of a region including the light emitting region R, the dummy contact region Ct_Dm, the light emitting region B, and the contact region Ct_Px_G when cut along the F direction.

[0163] The light emitting region R, the dummy contact region Ct_Dm, the light emitting region B, and the contact region Ct_Px_G are as described above. Also, in the regions Bb3 and Rb1 where the contact region Ct_Px_G is provided and the regions Bb1 and Rb3 where the dummy contact region Ct_Dm is provided, the coloring layer Cf_R is provided overlapping the coloring layer Cf_B, as described above.

[0164] In the contact regions Ct_Px_R, Ct_Px_G1, and Ct_Px_B, a reflection-enhancing layer 63, a first insulating layer 64, a second insulating layer 65, a protective layer 72, and a relay electrode 71 (71R, 71G) are sequentially provided from the reflective electrode 62 (62R, 62G, and 62B) to the pixel electrode 131. Therefore, in the contact regions Ct_Px_R, Ct_Px_G1, and Ct_Px_B, the distance Lpx from the reflective electrode 62 to the pixel electrode 131 is consistent in the pixel portions 110R, 110G, and 110B.

[0165] On the other hand, in the dummy contact region Ct_Dm, the reflection enhancing layer 63, the first insulating layer 64, the second insulating layer 65, the protective layer 72, the dummy relay electrode 71D, the first optical adjustment layer 67 and the second optical adjustment layer 68 are sequentially provided from the reflective electrode 62G to the pixel electrode 131G.

[0166] In other words, in the contact regions Ct_Px_R, Ct_Px_G, and Ct_Px_B, the first optical adjustment layer 67 and the second optical adjustment layer 68 are not provided as compared to the dummy contact region Ct_Dm. Therefore, in the dummy contact region Ct_Dm, the distance LDm from the reflective electrode 62G to the pixel electrode 131G is longer than the distance Lpx in the contact regions Ct_Px_R, Ct_Px_G1, and Ct_Px_B. That is, in the pixel portions 110R, 110G, and 110B, the distance to the pixel electrode 131 in the Z direction is the longest (thickest) in the dummy contact region Ct_Dm when the reflective electrode 62 is used as a reference.

[0167] The first sealing layer 81 is provided in a manner covering the common electrode 133. The planarization layer 82 provided in a manner covering the first sealing layer 81 is formed, for example, by screen printing. Screen printing is a printing method using a "screen" mixed with synthetic fibers and metal fibers, and an organic material such as epoxy resin is passed through the mesh of the screen by the movement of a scraper to print in a manner covering the first sealing layer 81. In screen printing, the intersection of the mesh presses the first sealing layer 81 as the scraper moves. When pressing, sometimes force cannot be applied evenly in the display area 100, and some areas are compressed more than other areas. In addition, in the manufacturing process of the electro-optical device 10, not limited to screen printing, there are many cases where some force is applied in the display area 100 to compress a part of the area.

[0168] In the compressed area, the light emitting layer 132 is locally thinned. In the part where the light emitting layer 132 is locally thinned, the resistance value becomes low, and a small current flows easily. When a small current flows, there is a tendency to emit red light with high efficiency. In addition, this red light is light in a wavelength band that resonates through an optical resonator with an optical distance LR with the highest luminous efficiency.

[0169] In order to prevent this phenomenon, the planarization layer 82 can be thickened. However, since the distance from the light emitting layer 132 to the colored layers Cf_R, Cf_G, ​​and Cf_B becomes longer, there is a problem that the viewing angle becomes narrower.

[0170] In this embodiment, when a part of the display region 100 is pressed, the pressing is suppressed because the dummy contact region Ct_Dm serves as a barrier layer, so that local thinning of the light emitting layer 132 in the light emitting regions R, G1, G2, and B can be suppressed.

[0171] In addition, the light-emitting layer 132 is thinned by pressing in the vicinity of the dummy contact region Ct_Dm. In the portion where the light-emitting layer 132 is locally thinned, there is a tendency to emit red light. The dummy contact region Ct_Dm is included in the coloring layer Cf_B when viewed from above. Therefore, even if it is assumed that the light-emitting layer 132 emits red light near the dummy contact region Ct_Dm due to the thinning, it is blocked by the coloring layer Cf_B, so the red light will not be seen by the observer.

[0172] Therefore, according to the present embodiment, it is possible to suppress a decrease in display quality due to local pressure on the display region 100 .

[0173] In this embodiment, the light-emitting regions R and B are repeatedly arranged in both the E direction and the F direction. Similarly, the light-emitting regions G1 and G2 are repeatedly arranged in both the E direction and the F direction. In such an arrangement of the light-emitting regions R, G1, G2, and B, Fig.24 As shown, in the structure of the first reference example in which the colored layers Cf_R, Cf_G, ​​and Cf_B are provided corresponding to the regions divided by the boundary lines, the following problems occur.

[0174] In the structure of the first reference example, since the coloring layer Cf_G is arranged continuously along the E direction, for example, among the light emitted from the light-emitting area G1 in the OLED 130G, not only the component along the Z direction but also a considerable amount of the component along the E direction (oblique light) passes through the coloring layer Cf_G.

[0175] The colored layer Cf_G is continuous not only in the E direction but also in the F direction. Therefore, a large amount of oblique light along the F direction among the light emitted from the light emitting region G1 passes through the colored layer Cf_G.

[0176] Regarding the light emitted from the light emitting region G2, a considerable amount of the oblique light along the E direction and the F direction also passes through the coloring layer Cf_G.

[0177] In the first reference example, the coloring layers Cf_R and Cf_B are alternately arranged along the E and F directions, that is, they are discontinuously arranged along the E and F directions, so oblique light emitted from one of the OLEDs 130R or 130G is shielded by the coloring layer corresponding to the other one.

[0178] Therefore, in the first reference example, the oblique light is easily visible in the light emitted from the OLED 130G, whereas the oblique light is difficult to be visible in the light emitted from the OLEDs 130R and 130B.

[0179] Therefore, in the first reference example, when viewed with oblique light along the E and F directions, the degree of color change due to the viewing angle in the oblique direction is different for green, red, and blue.

[0180] In addition, in the technology described in Patent Document 1, in order to express the color of one point, one of the four octagonal areas arranged in two rows and two columns is allocated a red light-emitting area, one is allocated a green light-emitting area, and the remaining two are allocated a blue light-emitting area, which is different from the present embodiment in which the two green light-emitting areas G1 and G2 are allocated to the diagonal areas. Therefore, in the technology described in Patent Document 1, it is assumed that the structure in which the two green light-emitting areas G1 and G2 are allocated to the diagonal areas is assumed to be Fig.24 The first reference example shown.

[0181] Next, a second reference example is described in which the difference in the degree of color change caused by the viewing angle relative to the oblique direction in the first reference example is eliminated for green, red, and blue. In the second reference example, in the regions Bb1, Bb2, Bb3, and Bb4 located between the light-emitting regions G1 and G2 in a plan view, a coloring layer having a color different from that of the light-emitting regions G1 and G2 is provided in a plan view, for example, Fig.25 Therefore, when viewed in cross section, as for the region Bb1, Fig.26 As shown, among the light emitted from the OLED 130G, the oblique light along the E direction is shielded by the color layer Cf_B.

[0182] Here, the region Bb1 is described, but the same applies to the regions Bb2, Bb3, and Bb4. That is, the regions Bb1, Bb2, Bb3, and Bb4 in the color layer Cf_B block the green light emitted from the light-emitting region G1 or G2. In addition, the color layer Cf_G allows the green light emitted from the light-emitting region G1 or G2 to pass through the Z direction.

[0183] Therefore, in the present embodiment, similarly to the red and blue oblique lights, the green oblique light is also difficult to be visually recognized, and therefore the degree of color change due to the viewing angle in the oblique direction is similar among red, green, and blue.

[0184] In addition, Fig.26 In the drawings, reference numeral 80 collectively represents a first sealing layer 81, a planarizing layer 82, and a second sealing layer 83. Reference numeral 90 is an adhesive layer for bonding a protective glass (not shown).

[0185] However, in the second reference example, in the luminescent regions R and B adjacent to each other in the E or F direction, there arises a problem in that the red and blue components along the E or F direction are observed differently in oblique light depending on the conditions of the coloring layers.

[0186] Fig. 27 2 is a cross-sectional view for explaining the problem of the second reference example. In the example of the figure, the red coloring layer Cf_R is provided to cover the light-emitting region R when viewed from above, so that the end of the coloring layer Cf_R passes over the opening Ap_R which is the outer edge of the pixel isolation layer 134 when viewed from above. In the coloring layer Cf_R provided in this way, the corners are blunted for heat treatment after patterning, etc., and become convex in cross-sectional view.

[0187] In the colored layers Cf_R and Cf_B, a protective glass is provided via the adhesive 80 , but due to the difference between the refractive index of the colored layer Cf_R and the refractive index of the adhesive 80 , an undesired light-collecting effect of a lens occurs in the convex-shaped colored layer Cf_R.

[0188] Therefore, as shown by the dotted line, the oblique red light passing through the vicinity of the opening end of the opening Ap_R is refracted by the focusing effect of the convex lens in the color layer Cf_R. Due to this refraction, the straight light of the dotted line cannot be seen, so the viewing angle characteristics of red are deteriorated.

[0189] In addition, the end of the colored layer Cf_B is also convex in cross-section, but since the end of the blue colored layer Cf_B is far from the opening end of the opening Ap_B, the blue oblique light does not pass through the convex portion and travels roughly straight. Therefore, the viewing angle characteristics of the blue light are not deteriorated compared to the viewing angle characteristics of the red light. Therefore, in the second reference example, there is a problem that the viewing angle characteristics of the red light may be deteriorated compared to the viewing angle characteristics of the blue light.

[0190] In general, the refractive index tends to increase as the wavelength of light passing through the medium increases. Therefore, the refractive indices of the coloring layers Cf_R, Cf_G, ​​and Cf_B increase in sequence. In addition, the refractive index of the coloring layer Cf_R for light in the third wavelength band may be higher than the refractive index of the coloring layer Cf_R for light in the first wavelength band.

[0191] In contrast, in this embodiment, between the light-emitting region R and the light-emitting region B adjacent to each other in the E or F direction, the red coloring layer Cf_R is overlapped with the blue coloring layer Cf_B. Fig.14 As shown, since the red colored layer Cf_R covers the blue colored layer Cf_B, the end of the red colored layer Cf_R reaches the vicinity of the blue opening Ap_B, and the end of the colored layer Cf_R is unlikely to have a convex shape.

[0192] Therefore, in this embodiment, the oblique red light having passed through the vicinity of the opening end of the opening Ap_R is not refracted by the focusing effect of the lens in the colored layer Cf_R but travels substantially straight, thereby reducing deterioration in the viewing angle characteristics of red.

[0193] Fig.15 This is an explanatory diagram showing the measurement of color change in the electro-optical device 10 of the present embodiment. The chromaticity when the diagonal center Cen of the display area 100 is observed from the front and the chromaticity when it is offset from the diagonal center by, for example, 20 degrees are measured using a colorimeter 200, and the chromaticity of the two is plotted in the u'v' coordinate system, and the color change is expressed by the distance (Δu'v') on the color space of the plot. The distance (Δu'v') on the color space is also called color difference, and when the color difference is greater than 0.02, it is considered that humans can perceive it.

[0194] In this description, observing the diagonal center Cen from the front means observing the diagonal center Cen of the display area 100 from a point at a vertical line P passing through the diagonal center Cen of the display area 100 and at a distance Q from the diagonal center Cen.

[0195] In addition, there are the following three cases where the angle is offset by 20 degrees from the diagonal center Cen.

[0196] That is, first, in a plane defined by the Y direction and the Z direction, the diagonal center Cen of the display area 100 is viewed from a position at a distance Q from the diagonal center Cen in a straight line obtained by tilting the plumb line P by 20 degrees with respect to the diagonal center Cen (YZ: longitudinal direction);

[0197] Second, in a plane defined by the X direction and the Z direction, the diagonal center Cen of the display area 100 is viewed from a point at a distance Q from the diagonal center Cen on a straight line obtained by tilting the plumb line P by 20 degrees with respect to the diagonal center Cen (XZ: horizontal direction);

[0198] Third, in the plane defined by the E direction and the Z direction, in the straight line obtained by tilting the plumb line P by 20 degrees with the diagonal center Cen as a reference, the diagonal center Cen of the display area 100 is viewed from a location away from the diagonal center Cen by a distance Q (EZ: tilt direction).

[0199] Fig.16 Graphs showing the results of measuring the color difference of the present embodiment, the second reference example, and the first reference example in the vertical, horizontal, and oblique directions. The second reference example in this case is an example in which the focusing effect of the lens is not produced.

[0200] As shown in the graph, in the first reference example, the color difference is less than 0.02 in the vertical and horizontal directions, but greater than 0.02 in the oblique direction. In contrast, in the present embodiment and the second reference example, the color difference is less than 0.02 in the vertical, horizontal, and oblique directions.

[0201] Therefore, it can be seen that in the present embodiment and the second reference example, even if the angle at which the display area 100 is observed changes, the color change is less than that in the first reference example.

[0202] As described above, the optical distances LR, LG, and LB in the optical resonator satisfy

[0203] LR>LG>LB

[0204] relationship.

[0205] In addition, in the present embodiment, the first reference example, and the second reference example, the thickness of the reflective electrodes 62R, 62G, and 62B is 150 nm, and the thickness of the pixel electrode 131 is 20 nm. In addition, in the pixel portion 110R, the design value based on the total thickness of the reflection-enhancing layer 63, the first insulating layer 64, the second insulating layer 65, the first optical adjustment layer 67, and the second optical adjustment layer 68 is about 175 nm. In the pixel portion 110G, the design value based on the total thickness of the reflection-enhancing layer 63, the first insulating layer 64, the second insulating layer 65, and the second optical adjustment layer 68 is about 120 nm. In the pixel portion 110B, the design value based on the total thickness of the reflection-enhancing layer 63, the first insulating layer 64, and the second insulating layer 65 is about 70 nm.

[0206] Furthermore, when viewed in the X direction and the Y direction, if the light emitting region B having the shortest optical distance is adjacent to the light emitting region R having the longest optical distance, a large step is generated at the boundary between the light emitting regions B and R.

[0207] If there is a large step at the boundary of the light emitting region, the step will locally thin the light emitting layer 132, reduce the resistance, and make current leak easily. When leakage current flows in the light emitting layer 132, undesired light emission occurs, narrowing the color gamut of the displayed image.

[0208] In particular, in a micro display panel such as this embodiment, since the light emitting area (opening) is small, it is greatly affected by the step. In addition, light emission based on leakage current tends to occur in red, which has high efficiency, that is, light emission occurs even with a small current.

[0209] In contrast, according to the present embodiment, in the Y direction, the light-emitting regions G1 and B are adjacent, and the light-emitting regions R and G2 are adjacent. In the X direction, the light-emitting regions R and G1 are adjacent, and the light-emitting regions G2 and B are adjacent. That is, in the present embodiment, when observed in the X direction and the Y direction, the light-emitting region B with the smallest optical distance is not adjacent to the light-emitting region R with the largest optical distance. In addition, in the present embodiment, when observed in the E direction and the F direction, the light-emitting regions B and R are adjacent across the contact region Ct_Px_G or the dummy contact region Ct_Dm. Therefore, according to the present embodiment, it is possible to prevent the light-emitting layer 132 from being locally thinned due to the steps in the light-emitting region, thereby suppressing abnormal light emission caused by the leakage current flowing through, and avoiding the narrowing of the color gamut of the displayed image.

[0210] <Modification>

[0211] The above-exemplified embodiments can be variously modified. The following examples illustrate specific modified modes that can be applied to the embodiments. Two or more modes arbitrarily selected from the following examples can also be combined within the scope of no contradiction.

[0212] In the pixel portions 110R, 110G, and 110B, the positional relationship between the light emitting region and the contact region is not limited to Figure 6 The positional relationship shown may also be the positional relationship of the following first modification, second modification, and third modification.

[0213] Fig.17 It is a plan view showing the arrangement of pixel electrodes 131R, 131G, 131B, etc. according to the first modification.

[0214] The first variant is an example in which the contact region is located in the F direction relative to the light-emitting region. Specifically, in the first variant, the contact region Ct_Px_R is located in the F direction relative to the light-emitting region R, the contact region Ct_Px_G is located in the F direction relative to the light-emitting region G1, the dummy contact region Ct_Dm is located in the F direction relative to the light-emitting region G2, and the contact region Ct_Px_B is located in the F direction relative to the light-emitting region B.

[0215] In the first modification, the arrangement of the coloring layers Cf_R, Cf_G, ​​and Cf_B is similar to that in the embodiment. Figure 7 Therefore, in the first modification, the region Bb1 overlaps with the contact region Ct_Px_R in a plan view, and the region Bb2 overlaps with the contact region Ct_Px_G in a plan view.

[0216] Fig.18 It is a plan view showing the arrangement of pixel electrodes 131R, 131G, 131B, etc. according to the second modification.

[0217] The second modification example is an example in which the contact region is located in the opposite direction of the F direction relative to the light-emitting region. Specifically, in the second modification example, the contact region Ct_Px_R is located in the opposite direction of the F direction relative to the light-emitting region R, the contact region Ct_Px_G is located in the opposite direction of the F direction relative to the light-emitting region G1, the dummy contact region Ct_Dm is located in the opposite direction of the F direction relative to the light-emitting region G2, and the contact region Ct_Px_B is located in the opposite direction of the F direction relative to the light-emitting region B.

[0218] In the second modification, the arrangement of the coloring layers Cf_R, Cf_G, ​​and Cf_B is similar to that in the embodiment. Figure 7 Therefore, in the second modification, the region Bb1 overlaps with the contact region Ct_Px_B in a plan view, and the region Bb2 overlaps with the dummy contact region Ct_Dm in a plan view.

[0219] Although not specifically shown in the figure, it is also possible to have an example where the contact region is located in the E direction relative to the light emitting region. However, when the contact region is located in the E direction relative to the light emitting region, region Bb1 overlaps with dummy contact region Ct_Dm in a plan view, and region Bb2 overlaps with contact region Ct_Px_R in a plan view, similarly to the embodiment.

[0220] Fig.19 1 is a plan view showing the arrangement of pixel electrodes 131R, 131G, 131B, etc. according to the third modification. In the third modification, the relationship between the contact region Ct_Px_G and the dummy contact region Ct_Dm is swapped with that of the embodiment in the pixel portion 110G.

[0221] In the third modification, the arrangement of the coloring layers Cf_R, Cf_G, ​​and Cf_B is similar to that in the embodiment. Figure 7 Therefore, in the third modification, the region Bb1 overlaps with the contact region Ct_Px_G in a plan view, and the region Bb2 overlaps with the contact region Ct_Px_B in a plan view.

[0222] In the embodiment, the shapes of the colored layers Cf_R, Cf_G, ​​and Cf_B are set as follows when viewed from above: Figure 8For example, the fourth modification is to make the shapes of the colored layers Cf_R, Cf_G, ​​and Cf_B as shown in the top view. Fig. 20 Examples of shapes shown.

[0223] As shown in the figure, in the fourth modification, the coloring layer Cf_G is not an octagon when viewed from above, but a quadrilateral with blunted corners. Specifically, the coloring layer Cf_G is smaller than the quadrilateral defined by the boundary line Edg of the pixel units 110R, 110G, and 110B by an amount corresponding to the blunted corners. On the contrary, a part of the four corners of the coloring layer Cf_R may protrude from the quadrilateral defined by the boundary line Edg. Similarly, a part of the four corners of the coloring layer Cf_B may protrude from the quadrilateral defined by the boundary line Edg.

[0224] In other words, Figure 8 In the embodiment shown in the figure, all four corners of the colored layers Cf_R and Cf_B protrude from the quadrilateral defined by the boundary line Edg. Fig. 20 In the fourth modification shown, only a part of the four corners of the colored layers Cf_R and Cf_B protrude from the quadrilateral defined by the boundary line Edg.

[0225] The areas of the light emitting regions R, G1, G2, and B in a plan view do not need to be equal to each other. This is because, as described above, the area of ​​each light emitting region is determined in consideration of light emitting efficiency, visibility, life of the light emitting layer, and the like.

[0226] Fig.21 It is a top view showing a fifth modified example in which the areas of the light-emitting regions R, G1, G2, and B are made different from each other.

[0227] In the fifth modification,

[0228] The area of ​​the light-emitting region R is less than the area of ​​the light-emitting region B and is less than the sum of the areas of the light-emitting regions G1 and G2.

[0229] In addition, the reason for setting the areas of each light-emitting area to such a relationship is that the luminous efficiency of red is the highest among red, green and blue, so the area can be minimized. On the other hand, green has high visibility, so in order to ensure the lifespan to withstand severe use, the area is set to the maximum.

[0230] In the fifth modification, although not particularly shown, the red colored layer Cf_R is provided to overlap the blue colored layer Cf_B between the light emitting regions G1 and G2 arranged along the E direction and the F direction.

[0231] In the embodiment, an OLED is cited as an example of a light-emitting element, but the present invention is not limited thereto, and an inorganic EL element or a μLED element using an inorganic material may also be used.

[0232] <Electronic equipment>

[0233] Next, an electronic device to which any of the electro-optical devices 10 in the embodiment and the first to fifth modifications is applied will be described. The electro-optical device 10 is suitable for applications where pixels are small in size and high-definition display is performed. Therefore, a head mounted display will be described as an example of an electronic device.

[0234] Fig. 22 is a diagram showing the appearance of a head mounted display. Fig.23 This is a diagram showing its optical structure.

[0235] First, if Fig. 22 As shown in FIG. 1 , the head mounted display 300 has temples 310, a nose bridge 320, and lenses 301L and 301R similar to ordinary glasses in appearance. Fig.23 As shown, the head mounted display 300 is provided with an electro-optical device 10L for the left eye and an electro-optical device 10R for the right eye near the nose bridge 320 and on the back side (lower side in the figure) of the lenses 301L and 301R.

[0236] The image display surface of the electro-optical device 10L is Fig.23 The image display surface of the electro-optical device 10R is arranged on the right side opposite to the electro-optical device 10L. Thus, the image display of the electro-optical device 10R is emitted in the direction of 3 o'clock in the figure via the optical lens 302R. The half-mirror 303R reflects the image display of the electro-optical device 10R in the direction of 6 o'clock, and on the other hand, allows light incident from the direction of 12 o'clock to pass through.

[0237] In this configuration, the wearer of the head mounted display 300 can observe the display images of the electro-optical devices 10L and 10R in a see-through state superimposed on the external scene.

[0238] In the head mounted display 300 , if the electro-optical device 10L displays the left eye image and the electro-optical device 10R displays the right eye image in binocular images with parallax, the wearer can perceive the displayed images as if they have depth and three-dimensionality.

[0239] In addition, electronic devices including the electro-optical device 10 can be applied to electronic viewfinders in video cameras or digital cameras with interchangeable lenses, portable information terminals, display units of watches, light valves of projection projectors, and the like, in addition to the head mounted display 300.

[0240] According to the above description, for example, the preferred embodiment of the present disclosure can be understood as follows. In addition, in order to easily understand each embodiment, the numbers of the drawings are collectively described in parentheses for convenience, but the present invention is not intended to be limited to the illustrated embodiments.

[0241] An electro-optical device (10) of one mode (mode 1) comprises, when viewed from above: a first light-emitting region (B) that emits light of a first wavelength band; a first colored layer (Cf_B) that transmits light of the first wavelength band; a second light-emitting region (G1) that is arranged adjacent to the first light-emitting region (B) in a first direction and emits light of a second wavelength band; a second colored layer (Cf_G) that is arranged to overlap with the second light-emitting region and transmits light of the second wavelength band; a third light-emitting region (R) that is arranged adjacent to the second light-emitting region (G1) in a second direction and emits light of a third wavelength band; a third colored layer (Cf_R) that is arranged to overlap with the third light-emitting region (R) and transmits light of the third wavelength band; and a fourth light-emitting region (G2) that is adjacent to the second light-emitting region (G1) in a first direction. and a fourth coloring layer (Cf_G) which is arranged adjacent to each other in a third direction intersecting with the second direction and emits light of the second band; and a fourth coloring layer (Cf_G) which is arranged to overlap with the fourth light-emitting area (G2) to allow light of the second band to pass through, the first coloring layer (Cf_B) includes a first area (Ba) overlapping with the first light-emitting area (B) when viewed from above and a second area (Bb1) located between the second light-emitting area (G1) and the fourth light-emitting area (G2) when viewed from above, the third coloring layer (Cf_R) includes a third area (Ra) overlapping with the third light-emitting area (R) when viewed from above and a fourth area (Rb3) located between the second light-emitting area (G1) and the fourth light-emitting area (G2) when viewed from above, and the second area (Bb1) at least partially overlaps with the fourth area (Rb3) when viewed from above.

[0242] In the first embodiment, between the second light-emitting region (G1) or the fourth light-emitting region (G2) adjacent in the third direction, the third coloring layer (Cf_R) is overlapped on the first coloring layer (Cf_B) that transmits light of a different wavelength band from the second light-emitting region (G1) or the fourth light-emitting region (G2). Since the end of the third coloring layer (Cf_R) is away from the end of the third light-emitting region (R), the focusing effect of the lens caused by the passivation of the end of the third coloring layer (Cf_R) can be suppressed. As a result, the field angle characteristics of the light of the third wavelength band can be improved.

[0243] In addition, the Y direction is an example of the first direction, the X direction is an example of the second direction, and the E direction is an example of the third direction. The light-emitting region B is an example of the first light-emitting region, the light-emitting region G1 is an example of the second light-emitting region, the light-emitting region R is an example of the third light-emitting region, and the light-emitting region G2 is an example of the fourth light-emitting region.

[0244] The colored layer Cf_B is an example of a first colored layer, the colored layer Cf_G is an example of a second colored layer and a fourth colored layer, and the colored layer Cf_R is an example of a third colored layer.

[0245] The region Ba is an example of the first region, the region Bb1 is an example of the second region, the region Ra is an example of the third region, and the region Rb3 is an example of the fourth region.

[0246] In the electro-optical device (10) of a specific embodiment (embodiment 2) of embodiment 1, the refractive index of the third colored layer (Cf_R) is higher than the refractive index of the first colored layer (Cf_B).

[0247] If the refractive index is high, the focusing effect of the lens becomes greater, which easily leads to deterioration of the viewing angle characteristics. However, according to method 2, the focusing effect of the lens can be suppressed, so the viewing angle characteristics of the light in the third wavelength band can be effectively improved.

[0248] In the electro-optical device (10) of a specific embodiment (embodiment 3) of embodiment 1, the refractive index of the third colored layer (Cf_R) for light in the third wavelength band is higher than the refractive index of the first colored layer (Cf_B) for light in the first wavelength band.

[0249] If the refractive index is high, the focusing effect of the lens becomes greater, which easily leads to deterioration of the viewing angle characteristics. However, according to method 2, the focusing effect of the lens can be suppressed, so the viewing angle characteristics of the light in the third wavelength band can be effectively improved.

[0250] In the electro-optical device (10) of a specific aspect (aspect 4) of aspect 1, the first wavelength band is shorter than the second wavelength band and the third wavelength band.

[0251] According to the fourth aspect, the light in the second wavelength band emitted from the second light emitting region (G1) or the fourth light emitting region (G2) along the third direction can be blocked by the first colored layer (Cf_B) having a short wavelength.

[0252] In the electro-optical device (10) of the specific embodiment (embodiment 5) of embodiment 1, the third coloring layer (Cf_R) is arranged on the front side of the first coloring layer (Cf_B). Since the oblique light from the third light-emitting region (R) passes through the third coloring layer (Cf_R) arranged on the front side of the first coloring layer (Cf_B), the viewing angle characteristics of the light in the third wavelength band can be improved. In addition, the front side refers to the emission side of the light from the light-emitting region.

[0253] The electro-optical device (10) of a specific embodiment of embodiment 1 (embodiment 6) comprises: a first light-emitting element (130B), which includes a common electrode (133), a first pixel electrode (131B) and a light-emitting layer (132); a first relay electrode (71B), which is electrically connected to the first pixel electrode (131B); a second light-emitting element (130G), which includes a common electrode (133), a second pixel electrode (131G) and a light-emitting layer (132); a second relay electrode (71G), which is electrically connected to the second pixel electrode (131G); a third light-emitting element (130R), which includes a common electrode (133), a third pixel electrode (131R) and a light-emitting layer (132); and a third relay electrode (71R), which is electrically connected to the second pixel electrode (131G). The third pixel electrode (131R) is electrically connected, the first light-emitting element (130B) emits light of the first band from the first light-emitting area (B), the second light-emitting element (130G) emits light of the second band from the second light-emitting area (G1) and the fourth light-emitting area (G2), and the third light-emitting element (130R) emits light of the third band from the third light-emitting area (R). The first light-emitting area (B) is the area where the first pixel electrode (131B) contacts the light-emitting layer (132), the second light-emitting area (G1) and the fourth light-emitting area (G2) are respectively the areas where the second pixel electrode (131G) contacts the light-emitting layer (132), and the third light-emitting area (R) is the area where the third pixel electrode (131R) contacts the light-emitting layer (132).

[0254] The pixel electrode 131B is an example of a first pixel electrode, the pixel electrode 131G is an example of a second pixel electrode, and the pixel electrode 131R is an example of a third pixel electrode. The relay electrode 71B is an example of a first relay electrode, the relay electrode 71G is an example of a second relay electrode, and the relay electrode 71R is an example of a third relay electrode.
