[0014] The first output terminal G1(i) has a function of supplying a first selection signal according to a first pulse width modulation signal during a period after the first trigger signal is supplied and before the second trigger signal is supplied, and the first output terminal G1(i) has a function of supplying a first selection signal during a period when a one-time selection signal is supplied.

As a result, a novel drive circuit with excellent convenience, practicality or reliability can be provided.

[0063] In the drawings of this specification, the components are classified according to their functions and shown as block diagrams that are independent of each other. However, it is difficult to completely divide the actual components according to their functions, and one component may involve multiple functions.
[0064] In this specification, the names of the source and drain of a transistor are interchanged according to the polarity of the transistor and the level of the potential applied to each terminal. Generally speaking, in an n-channel transistor, the terminal to which a low potential is applied is called the source, and the terminal to which a high potential is applied is called the drain. In addition, in a p-channel transistor, the terminal to which a low potential is applied is called the drain, and the terminal to which a high potential is applied is called the source. In this specification, although for convenience in some cases it is assumed that the source and drain are fixed to describe the connection relationship of the transistor, in fact, the names of the source and drain are interchanged according to the above-mentioned potential relationship.
[0065] In this specification, the source of a transistor refers to a source region of a part of a semiconductor film used as an active layer or a source electrode connected to the semiconductor film. Similarly, the drain of a transistor refers to a drain region of a part of the semiconductor film or a drain electrode connected to the semiconductor film. In addition, the gate refers to a gate electrode.
[0066] In this specification, a state in which transistors are connected in series refers to, for example, a state in which only one of the source and drain of a first transistor is connected to only one of the source and drain of a second transistor. Also, a state in which transistors are connected in parallel refers to a state in which one of the source and drain of a first transistor is connected to one of the source and drain of a second transistor and the other of the source and drain of the first transistor is connected to the other of the source and drain of the second transistor.
[0067] In this specification, connection refers to electrical connection, which is equivalent to a state in which current, voltage or potential can be supplied or transmitted. Therefore, the connection state does not necessarily refer to a direct connection state, but also includes a state in which current, voltage or potential can be supplied or transmitted through wiring, resistors, diodes, transistors and other circuit elements indirectly connected.
[0068] Even when independent components are connected to each other on the circuit diagram in this specification, there are cases where one conductive film actually has the functions of multiple components, for example, a part of the wiring is used as an electrode, etc. The category of connection in this specification includes such a case where one conductive film has the functions of multiple components.
[0069] In addition, in this specification, one of a first electrode and a second electrode of a transistor is a source electrode, and the other is a drain electrode.

[0072] Note that the description of these effects does not prevent the existence of other effects. One embodiment of the present invention does not necessarily have all of the above effects. Note that effects other than the above can be understood and extracted from the description of the specification, drawings, claims, etc. BRIEF DESCRIPTION OF THE DRAWINGS

[0121] In addition, the transistor M15 and the transistor M19 have the function of supplying the potential of the wiring GVSS to the node GN1(i) according to the first trigger signal. Thus, the operation of the trigger circuit SR(i) can be started. Alternatively, before the potential of the wiring GVSS is supplied to the node GN1(i), the node GN1(i) can be kept in a floating state.
[0122] Transistor M4

Note that the transistors M16 and M3 have a function of supplying the potential of the wiring GVDD to the node GN1(i) during the period when the second clock signal and the third clock signal overlap.
[0130] Transistor M20
[0131] The transistor M20 includes a gate electrode electrically connected to the terminal R(i). Note that, according to the potential of the terminal R(i), the transistor M20 supplies the potential of the wiring GVDD to the node GN1(i). For example, a reset signal may be supplied to the terminal R(i). Thus, the trigger circuit SR(i) may be reset.

[0133] The transistor M17, the transistor M21, and the transistor M31 include a gate electrode to which the potential of the wiring GVDD is supplied. Thus, for example, when the potential of the node GN4(i) is higher than the potential of the wiring GVDD, stress on the transistor M6, the transistor M12, and the transistor M22 can be suppressed. Alternatively, the node GN4(i) can be used to stably supply the output. Alternatively, stress between the first electrode and the second electrode included in the transistor M1, the transistor M5, and the transistor M18 can be suppressed.
[0134] Note that the flip-flop circuit SR(m+1) has the same structure as the flip-flop circuit SR(i) except that the input terminal RIN(i) and the transistor M4 are not included (see Figure 1B and Figure 2B ). In addition, it can be used for the last stage of the shift register circuit. Note that a transistor having a wider width of a region forming a channel than a transistor used for the flip-flop circuit SR(i) is suitable for the flip-flop circuit SR(m+1). Specifically, the width of a region forming a channel of the transistor M3 or the transistor M16 included in the flip-flop circuit SR(m+1) is wider than the width of a region forming a channel of the transistor M3 or the transistor M16 included in the flip-flop circuit SR(i).
[0135] <Structure example 3 of the flip-flop circuit>
[0136] The flip-flop circuit SR(i) described in this embodiment includes a transistor M13, a transistor M23, a transistor M7, a node GN1(i), and a wiring GVSS (see Figure 2A , Figure 2B , Figure 3A and Figure 3B ).

[0143] Transistor M7
[0144] The transistor M7 includes a gate electrode electrically connected to the node GN1 (i), a first electrode electrically connected to the output terminal OUT(i), and a second electrode electrically connected to the wiring GVSS.
[0145] The transistor M7 is in a non-conductive state during a period after the first trigger signal is supplied and before the second trigger signal is supplied.
[0146] Thus, the first selection signal and the second selection signal can be supplied after the first trigger signal is supplied and before the second trigger signal is supplied. Alternatively, the first selection signal can be supplied during the period when the one-time selection signal is supplied. As a result, a novel trigger circuit with excellent convenience, practicality or reliability can be provided.
[0147] <Structure example 4 of the flip-flop circuit>
[0148] The trigger circuit SR(i) described in this embodiment includes a transistor M24, a wiring GVDD (see Figure 3A and Figure 3B ).
[0149] The transistor M24 includes a gate electrode electrically connected to the wiring GVDD, a first electrode electrically connected to the node GN1 (i), and a second electrode electrically connected to the gate electrode of the transistor M13 .
[0150] Thus, the transistor M24 can be placed in a non-conductive state during the period TB when the one-shot selection signal is at a high level other than the period after the first trigger signal is supplied and before the second trigger signal is supplied (see Figure 3B or Figure 4B ). Alternatively, the potential of the node GN1(i) can be made lower than the potential obtained by subtracting the threshold voltage of the transistor M24 from the potential supplied from the wiring GVDD. Alternatively, the potential rise of the node GN1(i) can be suppressed from causing stress to the transistors M23, M7, M5, and M18. Alternatively, the potential rise of the node GN1(i) can be suppressed from causing stress to the transistors M15 and M19. As a result, a novel trigger circuit having excellent convenience, practicality, or reliability can be provided.
[0151] 《Potential of node GN2(i)》
[0152] The node GN2(i) is supplied with the potential of the wiring GVDD during the period when the first trigger signal is at a high level (see Figure 2A , Figure 2B and Figure 4A T1). In addition, during the period when the first trigger signal and the second trigger signal are at a low level and the potential of the node GN1(i) is lower than the value obtained by adding the threshold voltage of the transistor M5 to the potential supplied by the wiring GVDD or the value obtained by adding the threshold voltage of the transistor M18 to the potential supplied by the wiring GVDD, the node GN2(i) remains in a floating state (refer to Figure 4A T2).
[0153] Note that the node GN2 ( i ) is capacitively coupled to the output terminal G1 ( i ) via, for example, a capacitor C2 .
[0154] 《Potential of node GN1(i)》
[0155] The node GN1(i) is supplied with the potential of the wiring GVSS during the period when the first trigger signal is at a high level (see Figure 2A , Figure 2B and Figure 4A T1). In addition, the node GN1(i) remains in a floating state during the period when the first trigger signal and the second trigger signal are at a low level (refer to Figure 4A T2).
[0156] Note that, for example, the node GN1 (i) is capacitively coupled to the input terminal E(i) via the capacitor C5.
[0157] For example, when the trigger circuit SR(i) does not include the transistor M24, the potential of the node GN1(i) is affected by the potential of the input terminal E(i). Alternatively, the potential of the node GN1(i) is increased by, for example, the one-time selection signal (see Figure 2A , Figure 2B and Figure 4A T3). Alternatively, the potential of the node GN1(i) is close to a potential obtained by adding a voltage supplied by a one-time selection signal to a potential supplied to the wiring GVDD, for example.
[0158] On the other hand, when the trigger circuit SR(i) includes the transistor M24, the potential of the node GN3(i) is affected by the potential of the input terminal E(i). Alternatively, the potential of the node GN3(i) is increased by, for example, the one-time selection signal (see Figure 3A , Figure 3B and Figure 4B T3). Alternatively, the potential of the node GN3(i) is, for example, close to the potential of the potential supplied to the wiring GVDD plus the voltage when the one-time selection signal is high. Alternatively, the transistor M24 is in a non-conducting state. Alternatively, the potential of the node GN1(i) can be suppressed from being affected by the one-time selection signal. Alternatively, the potential of the node GN1(i) can be made lower than the potential obtained by subtracting the threshold voltage of the transistor M24 from the voltage supplied from the wiring GVDD. Alternatively, the one-time selection signal can be prevented from affecting the potential of the node GN1(i). Alternatively, the stress applied to the transistor including the gate electrode electrically connected to the node GN1(i) can be suppressed. Alternatively, the stress applied to the transistor M13, the transistor M23, the transistor M7, the transistor M5, and the transistor M18 can be suppressed. Alternatively, the stress applied to the transistor M15 and the transistor M19 can be suppressed. Alternatively, the stress applied to the transistor M16, the transistor M4, and the transistor M20 can be suppressed. As a result, a novel trigger circuit having excellent convenience, practicality, or reliability can be provided.

Alternatively, a group of trigger circuits can supply the second selection signal in a specified order. Alternatively, a group of trigger circuits can supply the first selection signal all at once. As a result, a novel drive circuit with excellent convenience, practicality or reliability can be provided.
[0173] 《Connection example of input terminal》
[0174] For example, the input terminal LIN(i) is electrically connected to the wiring SPL or the output terminal OUT(i-1) of the flip-flop circuit SR(i-1) (see Figure 1C and Figure 6 ).

[0176] The input terminal E(i) is electrically connected to the wiring VEE. Note that the wiring VEE supplies a one-time selection signal.
[0177] Input terminal A(i) is electrically connected to any one of wiring PWCA1 to wiring PWCA4. Note that wiring PWCA1 to wiring PWCA4 all supply a first pulse width modulation signal. For example, a rectangular wave may be used as the first pulse width modulation signal (see Figure 4A or Figure 5A ).
[0178] Input terminal B(i) is electrically connected to any one of wiring PWCB1 to wiring PWCB4. Note that wiring PWCB1 to wiring PWCB4 all supply pulse width modulation signals. For example, the same signal as the first pulse width modulation signal can be used as the second pulse width modulation signal (see Figure 4A Alternatively, a signal having a pulse width different from that of the first pulse width modulation signal may be used as the second pulse width modulation signal. Specifically, a signal having a pulse width shorter than that of the first pulse width modulation signal may be used as the second pulse width modulation signal (see Figure 5A ).

[0181] The output terminal OUT(i) is electrically connected to LIN(i+1) of the flip-flop circuit SR(i+1) and RIN(i) of the flip-flop circuit SR(i-2) (refer to Figure 6 ).
[0182] <Operation Example of Driving Circuit GD>
[0183] The drive circuit GD of one embodiment of the present invention sequentially supplies the selection signal. For example, during the period TA, the flip-flop circuit SR(1) to the flip-flop circuit SR(m+2) sequentially supply the selection signal (see Figure 4A and Figure 5A ).
[0184] In addition, the drive circuit GD according to one embodiment of the present invention supplies a selection signal at one time. For example, in the period TB, the flip-flop circuits SR(1) to SR(m+2) supply the selection signal at the same time.
[0185] Note that a period including the period TA and the period TB may be referred to as a 1 subframe (SUB FRAME) period.

[0200] The display element 750 (i, j) is electrically connected to the pixel circuit 530 (i, j) (see Fig. 8A and Figure 8B ).
[0201] For example, an element that controls light reflection, light transmission, or light emission can be used as a display element. Specifically, an electro-optical element or a light-emitting element can be used as a display element.

[0204] The scanning line GL1(i) is electrically connected to the output terminal G1(i), and the scanning line GL2(i) is electrically connected to the output terminal G2(i) (see Figure 6 ).
[0205] Thus, the first selection signal can be supplied to the first scan line GL1(i). Alternatively, the second selection signal can be supplied to the second scan line GL2(i). Alternatively, the first selection signal or the second selection signal can be used to drive the pixel 702(i, j).

[0225] In addition, the image signal is supplied to the capacitor C12. For example, the image signal is supplied using the potential difference between the potential supplied from the signal line SL1(j) and the potential supplied from the signal line SL2(j).
[0226] [Step 2]
[0227] In the second step, the switch SW12 is turned on while the switch SW11 is kept in the non-conductive state. For example, a one-time selection signal is supplied to the scanning line GL1 (i).

[0256] The drive circuit GDA and the drive circuit GDB can be used as the drive circuit GD. For example, the drive circuit GDA and the drive circuit GDB have a function of supplying a selection signal according to the control signal SP.
[0257] Specifically, the drive circuit GDA and the drive circuit GDB have a function of supplying a selection signal to one scanning line at a frequency of 30 Hz or more, preferably 60 Hz or more, according to the control signal SP. This allows a dynamic image to be displayed smoothly.
[0258] Alternatively, the drive circuits GDA and GDB have a function of supplying a selection signal to one scanning line at a frequency lower than 30 Hz, preferably lower than 1 Hz, and more preferably lower than 1 time / minute according to the control signal SP. Thus, a static image with suppressed flicker can be displayed.
[0259] For example, when a plurality of driving circuits are included, the frequency at which the driving circuit GDA supplies the selection signal may be different from the frequency at which the driving circuit GDB supplies the selection signal. Specifically, the selection signal may be supplied to the other region displaying the dynamic image at a higher frequency than the frequency at which the selection signal is supplied to the one region displaying the static image. Thus, a static image with suppressed flicker may be displayed in one region, and a dynamic image may be displayed smoothly in the other region.
[0260] Here, the frame frequency may be made variable. Alternatively, for example, the display may be performed at a frame frequency of 1 Hz or more and 120 Hz or less. Alternatively, the display may be performed at a frame frequency of 120 Hz in a progressive scanning manner.
[0261] 《Drive Circuit SD》
[0262] The drive circuit SD has a function of generating an image signal based on the data V11 and a function of supplying the image signal to a pixel circuit electrically connected to one display element (see Fig.10 ).
[0263] For example, various sequential circuits such as a shift register can be used for the drive circuit SD.
[0264] For example, an integrated circuit formed on a silicon substrate can be used for the drive circuit SD.
[0265] For example, the integrated circuit can be connected to the terminal using a COG (Chip on Glass) method or a COF (Chip on Film) method. Specifically, the integrated circuit can be connected to the terminal using an anisotropic conductive film.
[0266] Note that this embodiment mode can be combined with other embodiment modes described in this specification as appropriate.

[0271] <Structural Example 1 of Display Panel 700>
[0272] The display panel described in this embodiment includes a functional layer 520 (see Fig. 8A ).
[0273] 《Functional Layer 520》
[0274] The functional layer 520 includes the driver circuit GD described in Embodiment 2 and the pixel circuit 530 (i, j) described in Embodiment 3. Note that the functional layer 520 includes an opening 591A, and the pixel circuit 530 (i, j) is electrically connected to the display element 750 (i, j) at the opening 591A.
[0275] Thus, the semiconductor film for the transistor of the driving circuit GD can be formed in the process of forming the semiconductor film of the transistor for the pixel circuit 530 (i, j). In addition, the number of components can be reduced. As a result, a novel display panel with excellent convenience, practicality or reliability can be provided.
[0276] 《Structural example of transistor》
[0277] For example, a bottom-gate transistor or a top-gate transistor can be used for the driving circuit GD and the pixel circuit 530 (i, j) (see FIGS. 11 and 12 ).
[0278] The transistor includes a semiconductor film 508, a conductive film 504, a conductive film 512A, and a conductive film 512B (see Fig. 11B ).
[0279] The semiconductor film 508 includes a region 508A electrically connected to the conductive film 512A and a region 508B electrically connected to the conductive film 512B. The semiconductor film 508 includes a region 508C between the region 508A and the region 508B.

[0282] The conductive film 512A has one of the function of a source electrode and the function of a drain electrode, and the conductive film 512B has the other of the function of a source electrode and the function of a drain electrode.
[0283] In addition, the conductive film 524 can be used for a transistor. The conductive film 524 has a region in which the semiconductor film 508 is sandwiched between the conductive film 504 and the conductive film 504. The conductive film 524 has a function as a second gate electrode. The conductive film 524 can be electrically connected to the conductive film 504, for example. In addition, the conductive film 524 can be used for the scanning line GL2(i).
[0284] In the process of forming the semiconductor film for the transistor used in the pixel circuit 530 (i, j), the semiconductor film for the transistor used in the driver circuit GD can be formed.
[0285] 《Structural example 1 of semiconductor film 508.》
[0286] For example, a semiconductor containing a Group 14 element can be used for the semiconductor film 508. Specifically, a semiconductor containing silicon can be used for the semiconductor film 508.
[0287] [Hydrogenated amorphous silicon]
[0288] For example, hydrogenated amorphous silicon can be used for the semiconductor film 508. Alternatively, microcrystalline silicon or the like can be used for the semiconductor film 508. Thus, for example, a display panel with less display unevenness can be provided compared with a display panel using polycrystalline silicon for the semiconductor film 508. Alternatively, the display panel can be easily enlarged.
[0289] [Polysilicon]
[0290] For example, polycrystalline silicon can be used for the semiconductor film 508. Thus, for example, a higher field effect mobility can be achieved than a transistor using hydrogenated amorphous silicon for the semiconductor film 508. Alternatively, for example, a higher driving capability can be achieved than a transistor using hydrogenated amorphous silicon for the semiconductor film 508. Alternatively, for example, a higher pixel aperture ratio can be achieved than a transistor using hydrogenated amorphous silicon for the semiconductor film 508.
[0291] Alternatively, for example, higher reliability than that of a transistor using hydrogenated amorphous silicon for the semiconductor film 508 can be achieved.
[0292] Alternatively, for example, the temperature required to manufacture the transistor can be lower than that of a transistor using single crystal silicon.
[0293] Alternatively, a semiconductor film of a transistor for a driver circuit and a semiconductor film of a transistor for a pixel circuit can be formed by the same process. Alternatively, a driver circuit can be formed on the same substrate as a substrate on which a pixel circuit is formed. Alternatively, the number of components constituting an electronic device can be reduced.
[0294] [Single crystal silicon]
[0295] For example, single crystal silicon can be used for the semiconductor film 508. Thus, for example, a display panel with higher definition than that using hydrogenated amorphous silicon for the semiconductor film 508 can be realized. Alternatively, for example, a display panel with less display unevenness can be provided compared with a display panel using polycrystalline silicon for the semiconductor film 508. Alternatively, for example, smart glasses or a head-mounted display can be provided.
[0296] "Structural Example 2 of Semiconductor Film 508"
[0297] For example, a metal oxide may be used for the semiconductor film 508. As a result, the time during which the pixel circuit can hold an image signal can be extended compared to a pixel circuit using a transistor using amorphous silicon for a semiconductor film. Specifically, the occurrence of flicker can be suppressed, and a selection signal can be supplied at a frequency lower than 30 Hz, preferably lower than 1 Hz, and more preferably lower than 1 time / minute. As a result, fatigue of a user of the data processing device can be reduced. In addition, power consumption for driving can be reduced.
[0298] For example, a transistor using an oxide semiconductor can be used. Specifically, an oxide semiconductor containing indium or an oxide semiconductor containing indium, gallium, and zinc can be used for the semiconductor film.
[0299] For example, a transistor having a smaller leakage current in an off state than a transistor using amorphous silicon for a semiconductor film can be used. Specifically, a transistor using an oxide semiconductor for a semiconductor film can be used.
[0300] For example, a 25-nm-thick film containing indium, gallium, and zinc can be used as the semiconductor film 508 .
[0301] For example, a conductive film in which a 10-nm-thick film containing tantalum and nitrogen and a 300-nm-thick film containing copper are stacked can be used as the conductive film 504. The film containing copper includes a region in which the film containing tantalum and nitrogen is sandwiched between the insulating film 506 and the film containing copper.
[0302] For example, a stacked film of a 400 nm thick film containing silicon and nitrogen and a 200 nm thick film containing silicon, oxygen, and nitrogen can be used for the insulating film 506. The film containing silicon and nitrogen includes a region in which the film containing silicon, oxygen, and nitrogen is sandwiched between the film containing silicon and nitrogen and the semiconductor film 508.
[0303] For example, a conductive film in which a 50 nm thick film including tungsten, a 400 nm thick film including aluminum, and a 100 nm thick film including titanium are stacked in this order can be used as the conductive film 512A or the conductive film 512B. The film including tungsten includes a region in contact with the semiconductor film 508.
[0304] Here, for example, a production line of bottom-gate transistors containing amorphous silicon as a semiconductor can be easily converted into a production line of bottom-gate transistors containing oxide semiconductors as a semiconductor. Also, for example, a production line of top-gate transistors containing polycrystalline silicon as a semiconductor can be easily converted into a production line of top-gate transistors containing oxide semiconductors as a semiconductor. Either of the above conversions can effectively utilize existing production lines.
[0305] Thus, flickering can be suppressed. In addition, power consumption can be reduced. Alternatively, fast-moving dynamic images can be displayed smoothly. Alternatively, photos and the like can be displayed in rich grayscale. As a result, a novel display panel with excellent convenience, practicality or reliability can be provided.

[0311] For example, the conductive film 504, the conductive film 512A, and the insulating film 506 can be used for a capacitor.
[0312] The capacitor C12 includes a conductive film 754 (i, j), an electrode 751 (i, j) and an insulating film 521B (see Fig.11A ).
[0313] 《Structural example 1 of the functional layer 520.》

[0324] Compared with other organic materials, polyimide has better properties such as thermal stability, insulation, toughness, low dielectric constant, low thermal expansion coefficient, and chemical resistance. Therefore, polyimide is particularly preferably used for the insulating film 521 and the like.

For example, a silicon oxide film, a silicon nitride film, a silicon oxynitride film, an aluminum oxide film, or the like can be used.

[0398] For example, as the layer 753 containing a liquid crystal material, a liquid crystal material having an intrinsic resistivity of 1.0×10 13 Ω·cm or more, preferably 1.0×10 14 Ω·cm or more, more preferably 1.0×10 15 Liquid crystal materials with a resistance of Ω·cm or more.
[0399] Thus, it is possible to prevent current from flowing through the layer 753 including the liquid crystal material.

[0402] 《Structural Examples of Alignment Film AF1 and Alignment Film AF2》
[0403] The alignment film AF1 has a region sandwiched between the electrode 751 (i, j) and the layer 753 containing a liquid crystal material. In addition, the alignment film AF2 has a region sandwiched between the electrode 752 and the layer 753 containing a liquid crystal material.
[0404] An alignment film that aligns liquid crystals in a substantially horizontal direction can be used for the alignment film AF1 and the alignment film AF2. For example, an angle of about 2° to 5° can be set as the pretilt angle.
[0405] In addition, the alignment film AF2 is subjected to rubbing treatment so as to be anti-parallel to the alignment film AF1. In addition, the thickness of the alignment film AF1 or the alignment film AF2 can be set to 70 nm, for example.
[0406] 《Configuration example of electrode 751 (i, j) and electrode 752》
[0407] The electrode 752 is arranged so that an electric field that passes through the layer 753 including a liquid crystal material is formed between the electrode 752 and the electrode 751 .
[0408] 《Structural example 1 of layer 753 containing liquid crystal material.》
[0409] The layer 753 including a liquid crystal material scatters incident light I0 at a first scattering intensity when the electric field is in a first state.
[0410] In addition, the layer 753 including a liquid crystal material scatters the incident light I0 at a second scattering intensity when the electric field is in a second state greater than the first state. Note that the second scattering intensity is greater than the first scattering intensity.
[0411] The thickness of the layer 753 including a liquid crystal material can be set to, for example, 2.5 μm or more and 6.0 μm or less.
[0412] 《Structural example 2 of layer 753 containing liquid crystal material.》
[0413] The layer 753 containing a liquid crystal material contains a liquid crystal material and a polymer material, and the layer 753 containing a liquid crystal material is stabilized by the polymer.
[0414] 《Structural Examples of Liquid Crystal Materials》
[0415] For example, material MDA-00-3506 manufactured by Merck Ltd. may be used for the layer 753 including a liquid crystal material.
[0416] 《Structural Examples of Polymer Materials》
[0417] Polymer materials are copolymers of multifunctional monomers and monofunctional monomers.
[0418] 《Structural Examples of Multifunctional Monomers》
[0419] The multifunctional monomer has a benzoic acid phenyl skeleton. For example, a diacrylate having a benzoic acid phenyl skeleton can be used as the multifunctional monomer. Specifically, a material represented by the following structural formula (1) can be used as the multifunctional monomer.
[0420] [Chemical formula 1]
[0421]
[0422] 《Structural Examples of Multifunctional Monomers》

[0425]
[0426] [Chemical formula 3]
[0427]
[0428] [Chemical formula 4]
[0429]
[0430] Thus, at a second electric field strength greater than the first electric field strength, the incident light can be scattered more strongly. In addition, the power consumed in a state where the incident light is easily transmitted can be reduced. As a result, a novel liquid crystal element with excellent convenience, practicality or reliability can be provided.
[0431] The phenyl benzoate group has a structure represented by the structural formula (5), and the cyclohexylbenzene group has a structure represented by the structural formula (6). The phenyl benzoate group and the cyclohexylbenzene group may both have substituents.

[0435]
[0436] <Structural Example 2 of Liquid Crystal Element>
[0437] In addition, the second scattering intensity of the liquid crystal element described in this embodiment is 10 times or more the first scattering intensity.
[0438] This can improve the contrast between the state of transmitting incident light and the state of scattering incident light. As a result, a novel liquid crystal element with excellent convenience, practicality or reliability can be provided.

[0502] Note that this embodiment mode can be combined with other embodiment modes described in this specification as appropriate.
[0503] (Implementation method 6)
[0504] In this embodiment, refer to Fig.15 The structure of an input / output device according to one embodiment of the present invention will be described.
[0505] Fig.15 This is a block diagram showing the structure of an input / output device according to one embodiment of the present invention.
[0506] <Configuration Example 1 of Input / Output Device>
[0507] The input / output device described in this embodiment includes an input unit 240 and a display unit 230 (see Fig.15 ).
[0508] <Display unit 230>
[0509] The display portion 230 includes a display panel. For example, the display panel 700 described in Embodiment 3 or Embodiment 4 can be used for the display portion 230. In addition, a structure including the input portion 240 and the display portion 230 can be referred to as an input-output panel 700TP.
[0510] 《Configuration example 1 of the input unit 240.》
[0511] The input unit 240 includes a detection area 241. The input unit 240 has a function of detecting an object approaching the detection area 241.
[0512] The detection area 241 includes an area overlapping with the pixel 702 ( i, j ).
[0513] Thus, an object approaching an area overlapping with the display unit can be detected while the display unit is displaying image data. Alternatively, a finger or the like approaching the display unit can be used as an indicator to input position data. Alternatively, the position data can be associated with the image data displayed on the display unit. As a result, a novel input / output device with excellent convenience, practicality or reliability can be provided.
[0514] <<Structural example 1 of the detection area 241.>>
[0515] The detection area 241 includes, for example, one or more detectors.
[0516] The detection area 241 includes a group of detectors 802(g, 1) to 802(g, q) and another group of detectors 802(1, h) to 802(p, h). g is an integer greater than 1 and less than p, h is an integer greater than 1 and less than q, and p and q are integers greater than 1.
[0517] A set of detectors 802(g, 1) to 802(g, q) includes detector 802(g, h) and is arranged in the row direction (the direction indicated by arrow R2 in the drawing), and a set of detectors 802(g, 1) to 802(g, q) is electrically connected to wiring CL(g). Note that the direction indicated by arrow R2 may be the same as or different from the direction indicated by arrow R1.
[0518] Another group of detectors 802(1, h) to detector 802(p, h) includes detector 802(g, h) and is arranged in the column direction intersecting the row direction (the direction indicated by arrow C2 in the drawing), and the other group of detectors 802(1, h) to detector 802(p, h) is electrically connected to wiring ML(h).
[0519] Detector
[0520] The detector has a function of detecting an approaching indicator. For example, a finger or a stylus pen can be used as the indicator. For example, a metal sheet or a coil can be used as the stylus pen.
[0521] Specifically, an electrostatic capacitance type proximity sensor, an electromagnetic induction type proximity sensor, an optical type proximity sensor, a resistance film type proximity sensor, or the like can be used for the detector.
[0522] In addition, multiple types of detectors may be combined. For example, a detector for detecting a finger and a detector for detecting a stylus pen may be used in combination.
[0523] Therefore, the type of indicator can be identified. Alternatively, different instructions can be associated with the detection data according to the identified type of indicator. Specifically, in the case where it is determined that a finger is used as an indicator, the detection data can be associated with an action. Alternatively, in the case where it is determined that a stylus pen is used as an indicator, the detection data can be associated with a drawing process.
[0524] Specifically, an electrostatic capacitance type, a pressure sensitive type, or an optical proximity sensor may be used to detect a finger, or an electromagnetic induction type or an optical proximity sensor may be used to detect a stylus pen.
[0525] 《Configuration example 2 of the input unit 240.》
[0526] The input unit 240 may include an oscillation circuit OSC and a detection circuit DC (see Fig.15 ).
[0527] The oscillation circuit OSC supplies the search signal to the detector 802 (g, h). For example, a rectangular wave, a saw wave, a triangle wave, a sine wave, or the like can be used as the search signal.
[0528] The detector 802 ( g, h ) generates and supplies a detection signal that varies according to the distance from the pointer approaching the detector 802 ( g, h ) and the search signal.
[0529] The detection circuit DC supplies input data according to the detection signal.
[0530] Thus, the distance of the approaching pointer from the detection area 241 can be detected. In addition, the position where the pointer is closest to the detection area 241 can be detected.
[0531] Note that this embodiment mode can be combined with other embodiment modes described in this specification as appropriate.

[0563] For example, the user can use a finger in contact with the touch panel as a pointer to perform various gestures (tap, drag, slide, pinch, etc.).
[0564] For example, the computing device 210 analyzes data such as the position or trajectory of the finger touching the touch panel, and when the analysis result satisfies a predetermined condition, it can be said that a predetermined gesture is provided. Thus, the user can use the gesture to provide a predetermined operation instruction that is pre-set to be associated with the predetermined gesture.
[0565] For example, the user may provide a "scroll instruction" for changing the display position of image data using a gesture of moving a finger in contact with the touch panel along the touch panel.
[0566] The user can provide a "drag instruction" to remove the display guide panel NP at the end of the display area 231 by using a gesture of moving a finger in contact with the end of the display area 231 (refer to Fig. 16C).

[0579] The artificial intelligence unit 213 is supplied with input data II or detection data DS, and the artificial intelligence unit 213 infers control data CI based on the input data II or detection data DS. In addition, the artificial intelligence unit 213 supplies control data CI.
[0580] Thus, control data CI capable of displaying a sense of comfort can be generated. Alternatively, a display capable of displaying a sense of comfort can be generated. Alternatively, a display capable of displaying a sense of comfort can be generated. As a result, a novel data processing device with excellent convenience, practicality or reliability can be provided.
[0581] [Natural language processing of input data II]
[0582] Specifically, the artificial intelligence unit 213 can perform natural language processing on the input data II to extract a feature from the entire input data II. For example, the artificial intelligence unit 213 can infer the emotion included in the input data II and extract the emotion as a feature. In addition, the artificial intelligence unit 213 can infer the color, pattern, or font that is experienced as suitable for the feature. In addition, the artificial intelligence unit 213 can generate data for specifying the color, pattern, or font of the text and data for specifying the color or pattern of the background and use them as the control data CI.

For example, the artificial intelligence unit 213 can extract grammatical errors, misrecognition of facts, or expressions of emotions. In addition, the artificial intelligence unit 213 can generate control data CI that displays the extracted part in a different color, pattern, or font from another part, and use it for the control data CI.
[0584] [Image processing of input data II]
[0585] Specifically, the artificial intelligence unit 213 can perform image processing on the input data II to extract a feature from the input data II. For example, the artificial intelligence unit 213 can infer the age of the input data II, whether it is taken indoors or outdoors, whether it is daytime or nighttime, etc., and use them as features. In addition, the color tone that is empirically felt to be suitable for the feature can be inferred and the control data CI for displaying the color tone can be generated. Specifically, data specifying a color for shade expression (for example, full color, black and white, or brown, etc.) can be used as the control data CI.
[0586] Specifically, the artificial intelligence unit 213 performs image processing on the input data II to extract a portion of the image included in the input data II. For example, control data CI that displays a boundary between the extracted portion of the image and another portion of the image may be generated. Specifically, control data CI that displays a rectangle surrounding the extracted portion of the image may be generated.
[0587] [Inference using detection data DS]
[0588] Specifically, the artificial intelligence unit 213 may generate inference RI using the detection data DS, or generate control data CI based on the inference RI to allow the user of the data processing device 200 to use the device comfortably.

[0590] In addition, a clock signal or a timing signal supplied to the control unit 238 included in the display unit 230 may be used as the control data CI. Alternatively, a clock signal or a timing signal supplied to the control unit 248 included in the input unit 240 may be used as the control data CI.
[0591] <Configuration example 2 of a data processing device>
[0592] Reference Fig.17A and Fig. 17B Another configuration of the data processing device according to one embodiment of the present invention will be described.
[0593] "program"
[0594] The procedure of one embodiment of the present invention comprises the following steps (see Fig.17A ).
[0595] [First step]
[0596] In the first step, the settings are initialized (see Fig.17A(S1)).
[0597] For example, predetermined image data to be displayed at startup, a predetermined mode for displaying the image data, and data specifying a predetermined display method for displaying the image data are obtained from the storage unit 212. Specifically, a static image data or other dynamic image data can be used for the predetermined image data. In addition, the first mode or the second mode can be used for the predetermined mode.
[0598] [Step 2]
[0599] In the second step, interrupt processing is enabled (see Fig.17A (S2)). The computing device for which the interrupt processing is allowed can perform the interrupt processing while performing the main processing. The computing device that returns to the main processing from the interrupt processing can reflect the result obtained by the interrupt processing to the main processing.
[0600] When the counter is at the initial value, the computing device is caused to perform interrupt processing, and when recovering from the interrupt processing, the counter can also be set to a value other than the initial value. Thus, the interrupt processing can be performed at any time after the program is started.
[0601] [Third step]
[0602] In the third step, the image data is displayed using the predetermined mode or predetermined display method selected in the first step or the interrupt processing (refer to Fig.17A (S3)). Note that the predetermined mode specifies the mode of display data, and the predetermined display method specifies the method of displaying image data. In addition, for example, image data VI can be used as the displayed data.
[0603] For example, one method of displaying the image data VI may be associated with the first mode. Alternatively, another method of displaying the image data VI may be associated with the second mode. Thus, a display method may be selected according to the selected mode.
[0604] First Mode
[0605] Specifically, a method of supplying a selection signal to one scanning line at a frequency of 30 Hz or more, preferably 60 Hz or more, and performing display according to the selection signal may be associated with the first mode.
[0606] For example, by supplying the selection signal at a frequency of 30 Hz or higher, preferably 60 Hz or higher, a dynamic image can be displayed smoothly.
[0607] For example, by updating the image at a frequency of 30 Hz or more, preferably 60 Hz or more, an image that changes smoothly in accordance with the user's operation can be displayed on the data processing device 200 being operated by the user.
[0608] Second Mode
[0609] Specifically, a method of supplying a selection signal to one scanning line at a frequency lower than 30 Hz, preferably lower than 1 Hz, and more preferably lower than 1 time / minute and performing display according to the selection signal may be associated with the second mode.
[0610] By supplying the selection signal at a frequency lower than 30 Hz, preferably lower than 1 Hz, and more preferably lower than 1 time / minute, a display with suppressed flicker can be performed. In addition, power consumption can be reduced.
[0611] For example, when the data processing device 200 is used as a clock, the display may be updated once per second or once per minute.
[0612] Here, for example, when a light-emitting element is used as a display element, the light-emitting element can be caused to emit light in a pulsed manner to display image data. Specifically, an organic EL element can be caused to emit light in a pulsed manner and display can be performed using the afterglow. Since the organic EL element has excellent frequency characteristics, the driving time of the light-emitting element can sometimes be shortened to reduce power consumption. Alternatively, since the heat generation of the light-emitting element is suppressed, the degradation of the light-emitting element can sometimes be reduced.
[0613] [Step 4]
[0614] In the fourth step, when the end instruction is supplied (Yes), the process proceeds to the fifth step, and when the end instruction is not supplied (No), the process proceeds to the third step (refer to Fig.17A (S4)).
[0615] For example, the determination can be made based on an end instruction supplied during interrupt processing.
[0616] [Step 5]
[0617] Finish the work in step 5 (refer to Fig.17A (S5)).
[0618] Interrupt handling
[0619] The interrupt processing includes the following steps 6 to 8 (refer to Fig. 17B ).
[0620] [Step 6]
[0621] In the sixth step, for example, the detection unit 250 detects the illuminance of the environment in which the data processing device 200 is used (see Fig. 17B (S6)). In addition, the color temperature or chromaticity of the ambient light may be detected instead of the ambient illuminance.
[0622] [Step 7]
[0623] In the seventh step, a display method is determined based on the detected illumination data (see Fig. 17B (S7)). For example, the display brightness is set to be neither too dark nor too bright.
[0624] When the color temperature of the ambient light or the chromaticity of the ambient light is detected in the sixth step, the display color may also be adjusted.
[0625] [Step 8]
[0626] In the eighth step, the interrupt processing is terminated (refer to Fig. 17B (S8)).
[0627] <Configuration Example 3 of Data Processing Device>
[0628] Another configuration of the data processing device according to one embodiment of the present invention will be described with reference to FIG. 18 .
[0629] Fig.18A It is a flowchart of a program for explaining one embodiment of the present invention. Fig.18A Is the description and Fig. 17B The interrupt handling shown is a flowchart of different interrupt handling.
[0630] Example 3 of the structure of the data processing device and reference Fig. 17B The interrupt processing described above is different in that the interrupt processing includes a step of changing the mode according to a supplied predetermined event. Here, the difference is described in detail, and the above description is cited for the part that can use the same structure as the above structure.
[0631] Interrupt handling
[0632] The interrupt processing includes the following steps 6 to 8 (refer to Fig.18A ).
[0633] [Step 6]
[0634] In the sixth step, when the predetermined event is provided (yes), the seventh step is entered; when the predetermined event is not provided (no), the eighth step is entered (refer to Fig.18A (U6)). For example, whether a predetermined event is supplied within a predetermined period may be used as a condition. Specifically, the predetermined period may be longer than 0 seconds and less than 5 seconds, less than 1 second, or less than 0.5 seconds, preferably less than 0.1 seconds.
[0635] [Step 7]
[0636] In the seventh step, change the mode (refer to Fig.18A (U7)). Specifically, when the first mode is previously selected, the second mode is selected; when the second mode is previously selected, the first mode is selected.
[0637] For example, the display mode of a part of the display unit 230 may be changed. Specifically, the display mode of a region to which one of the drive circuits GDA, GDB, and GDC of the display unit 230 supplies a selection signal may be changed (see Fig.18B ).
[0638] For example, when a predetermined event is supplied to the input unit 240 in a region overlapping with a region where the drive circuit GDB supplies a selection signal, the display mode of the region where the drive circuit GDB supplies a selection signal may be changed (refer to Fig.18B and Fig.18C Specifically, the frequency of the selection signal supplied by the driving circuit GDB can be changed according to an event (eg, "tap") supplied to the touch panel using a finger or the like.
[0639] In addition, the signal GCLK is a clock signal for controlling the operation of the driving circuit GDB, and the signals PWC1 and PWC2 are pulse width modulation signals for controlling the operation of the driving circuit GDB. The driving circuit GDB supplies selection signals to the scanning lines G2(m+1) to G2(2m) according to the signals GCLK, PWC1, and PWC2.
[0640] Thus, for example, the drive circuit GDB can be made to supply a selection signal when the drive circuits GDA and GDC do not supply a selection signal. Alternatively, the display of the area where the drive circuit GDB supplies a selection signal can be updated without changing the display of the area where the drive circuits GDA and GDC supply a selection signal. Alternatively, the power consumed by the drive circuit can be reduced.
[0641] [Step 8]
[0642] In the eighth step, the interrupt processing is terminated (refer to Fig.18A (U8)). Alternatively, the interrupt processing may be repeatedly performed while the main processing is being performed.
[0643] Scheduled Events
[0644] For example, events such as “click” or “drag” provided by a pointing device such as a mouse may be used, and events such as “tap”, “drag” or “slide” provided by a touch panel may be used using a finger or the like as a pointer.
[0645] For example, the position of the slide bar indicated by the indicator, the sliding speed, the dragging speed, etc. may be used to supply the parameters of the instruction associated with the predetermined event.
[0646] For example, a preset threshold value may be compared with the data detected by the detection unit 250 , and the comparison result may be used for the event.
[0647] Specifically, a pressure-sensitive detector or the like that contacts a button or the like provided in a pushable manner in the housing can be used for the detection unit 250 .
[0648] 《Instructions associated with scheduled events》
[0649] For example, the end instruction may be associated with a predetermined event.
[0650] For example, a "page turning instruction" for switching one displayed image data to another image data can be associated with a predetermined event. In addition, a parameter for determining the page turning speed, etc., used when executing the "page turning instruction" can be supplied using the predetermined event.
[0651] For example, a "scroll instruction" for moving the display position of a portion of image data being displayed and displaying other portions continuous with the portion can be associated with a predetermined event. In addition, a predetermined event can be used to supply parameters for determining the speed of moving the display, etc., used when executing the "scroll instruction".
[0652] For example, an instruction to set a display method or an instruction to generate image data may be associated with a predetermined event. In addition, a parameter that determines the brightness of the generated image may be associated with a predetermined event. In addition, a parameter that determines the brightness of the generated image may be determined based on the brightness of the environment detected by the detection unit 250.
[0653] For example, an instruction to obtain data transmitted using a push service using the communication unit 290 may be associated with a predetermined event.
[0654] Furthermore, the position data detected by the detection unit 250 can also be used to determine whether or not the user is eligible to obtain data. Specifically, when the user is in a predetermined classroom, school, conference room, company, house, etc., the user can be determined to be eligible to obtain data. Thus, for example, teaching materials transmitted in a classroom at a school or university can be received, and the data processing device 200 can be used as a textbook, etc. (see Fig. 16C ). Alternatively, data transmitted to a conference room of a company or the like can be received and used as conference data.
[0655] Note that this embodiment mode can be combined with other embodiment modes described in this specification as appropriate.

[0693] [Example]
[0694] In this embodiment, refer to Fig. 22 The structure of the display device according to one embodiment of the present invention that was manufactured and the evaluation results are described.
[0695] Fig. 22 It is a diagram for explaining the display performance of a display device according to one embodiment of the present invention.
[0696] <Structure of Manufactured Display Device>
[0697] The display device includes a display panel and a light source.
[0698] 《Structure of display device》
[0699] Table 1 shows the specifications of the manufactured display device.
[0700] [Table 1]
[0701]
[0702] <Show results>
[0703] Displaying an image on the manufactured display device (refer to Fig. 22 ).
[0704] Note that this embodiment can be combined with other embodiment modes described in this specification as appropriate.
[0705] For example, in this specification, etc., when it is clearly stated that "X is connected to Y", the cases disclosed in this specification, etc. include: a case where X is electrically connected to Y; a case where X is functionally connected to Y; and a case where X is directly connected to Y. Therefore, the connection relationship other than the connection relationship shown in the drawings or the text is not limited to the predetermined connection relationship, and the connection relationship other than the connection relationship shown in the drawings or the text is also disclosed in the drawings or the text.
[0706] Here, X and Y are objects (for example, devices, elements, circuits, wirings, electrodes, terminals, conductive films, layers, etc.).
[0707] As an example of the case where X and Y are directly connected, there can be cited a case where an element capable of electrically connecting X and Y (such as a switch, transistor, capacitor, inductor, resistor, diode, display element, light emitting element, load, etc.) is not connected between X and Y, and a case where X and Y are connected without an element capable of electrically connecting X and Y (such as a switch, transistor, capacitor, inductor, resistor, diode, display element, light emitting element, load, etc.).
[0708] As an example of a case where X and Y are electrically connected, one or more elements (such as switches, transistors, capacitors, inductors, resistors, diodes, display elements, light-emitting elements, loads, etc.) that can electrically connect X and Y can be connected between X and Y. In addition, the switch has a function of controlling on and off. In other words, the switch has a function of controlling whether to allow current to flow by controlling to become a conducting state (on state) or a non-conducting state (off state). Alternatively, the switch has a function of selecting and switching a current path. In addition, the case where X and Y are electrically connected includes the case where X and Y are directly connected.
[0709] As an example of a case where X and Y are functionally connected, one or more circuits capable of functionally connecting X and Y (for example, a logic circuit (inverter, NAND circuit, NOR circuit, etc.), a signal conversion circuit (DA conversion circuit, AD conversion circuit, γ (gamma) correction circuit, etc.), a potential level conversion circuit (power supply circuit (boost circuit, step-down circuit, etc.), a level converter circuit that changes the potential level of a signal, etc.), a voltage source, a current source, a switching circuit, an amplifier circuit (a circuit capable of increasing signal amplitude or current, etc., an operational amplifier, a differential amplifier circuit, a source follower circuit, a buffer circuit, etc.), a signal generation circuit, a storage circuit, a control circuit, etc.) may be connected between X and Y. Note that, for example, even if another circuit is interposed between X and Y, when a signal output from X is transmitted to Y, it can be said that X and Y are functionally connected. In addition, the case where X and Y are functionally connected includes the case where X and Y are directly connected and the case where X and Y are electrically connected.
[0710] Furthermore, when it is explicitly stated that “X and Y are electrically connected”, the cases disclosed in this specification etc. include: a case where X and Y are electrically connected (in other words, a case where X and Y are connected with another element or another circuit interposed therebetween); a case where X and Y are functionally connected (in other words, a case where X and Y are functionally connected with another circuit interposed therebetween); and a case where X and Y are directly connected (in other words, a case where X and Y are connected without another element or another circuit interposed therebetween). In other words, when it is explicitly stated that “X and Y are electrically connected”, it means that the contents disclosed in this specification etc. include the same contents as the case where it is only explicitly stated that “connected”.
[0711] Note that, for example, a case where the source (or first terminal, etc.) of a transistor is electrically connected to X through Z1 (or not through Z1) and the drain (or second terminal, etc.) of the transistor is electrically connected to Y through Z2 (or not through Z2) and a case where the source (or first terminal, etc.) of the transistor is directly connected to a part of Z1 and another part of Z1 is directly connected to X, the drain (or second terminal, etc.) of the transistor is directly connected to a part of Z2 and another part of Z2 is directly connected to Y can be expressed as follows.
[0712] For example, it can be expressed as "X, Y, the source (or first terminal, etc.) of the transistor, and the drain (or second terminal, etc.) of the transistor are electrically connected to each other, and are electrically connected in the order of X, the source (or first terminal, etc.) of the transistor, the drain (or second terminal, etc.) of the transistor, and Y". Alternatively, it can be expressed as "the source (or first terminal, etc.) of the transistor is electrically connected to X, the drain (or second terminal, etc.) of the transistor is electrically connected to Y, and X, the source (or first terminal, etc.) of the transistor, the drain (or second terminal, etc.) of the transistor, and Y are electrically connected in sequence". Alternatively, it can be expressed as "X is electrically connected to Y through the source (or first terminal, etc.) and drain (or second terminal, etc.) of the transistor, and X, the source (or first terminal, etc.) of the transistor, the drain (or second terminal, etc.) of the transistor, and Y are arranged to be connected to each other in sequence". By specifying the connection order in the circuit structure using the same expression method as this example, the source (or first terminal, etc.) and drain (or second terminal, etc.) of the transistor can be distinguished to determine the technical scope.
[0713] In addition, as another expression method, for example, it can be expressed as "the source (or first terminal, etc.) of the transistor is electrically connected to X through at least a first connection path, the first connection path does not have a second connection path, the second connection path is a path between the source (or first terminal, etc.) of the transistor and the drain (or second terminal, etc.) of the transistor, the first connection path is a path through Z1, the drain (or second terminal, etc.) of the transistor is electrically connected to Y through at least a third connection path, the third connection path does not have the second connection path, and the third connection path is a path through Z2". Alternatively, it can also be expressed as "the source (or first terminal, etc.) of the transistor is electrically connected to X through Z1 at least on the first connection path, the first connection path does not have a second connection path, the second connection path has a connection path through the transistor, the drain (or second terminal, etc.) of the transistor is electrically connected to Y through Z2 at least on the third connection path, and the third connection path does not have the second connection path". Alternatively, it can be expressed as "the source (or first terminal, etc.) of the transistor is electrically connected to X through Z1 via at least a first electrical path, the first electrical path does not have a second electrical path, the second electrical path is an electrical path from the source (or first terminal, etc.) of the transistor to the drain (or second terminal, etc.) of the transistor, the drain (or second terminal, etc.) of the transistor is electrically connected to Y via Z2 via at least a third electrical path, the third electrical path does not have a fourth electrical path, and the fourth electrical path is an electrical path from the drain (or second terminal, etc.) of the transistor to the source (or first terminal, etc.) of the transistor". By using the same expression method as these examples to define the connection path in the circuit structure, the source (or first terminal, etc.) and drain (or second terminal, etc.) of the transistor can be distinguished to determine the technical scope.
[0714] Note that this expression method is an example and is not limited to the above expression method. Here, X, Y, Z1, and Z2 are objects (for example, devices, elements, circuits, wirings, electrodes, terminals, conductive films and layers, etc.).
[0715] In addition, even if independent components are electrically connected to each other on a circuit diagram, one component may have the functions of multiple components. For example, when a portion of a wiring is used as an electrode, one conductive film has the functions of both wiring and electrode. Therefore, the category of "electrically connected" in this specification also includes the case where one conductive film has the functions of multiple components.
