[0037]

[0038]

[0039] <Security device> Hereinafter, each element constituting the security device 100 will be described.

[0039] 《Housing》 The housing 101 has a light emitting element 120, an imaging unit 150, and an opener disposed therein (FIG. 1(B)) .

[0040] The size of the housing 101 is preferably such that it can be grasped by the user of the security device 100, and particularly preferably such that it can be grasped with one hand. For example, the housing 101 can be grasped using the thumb, index finger, and middle finger. and held.

[0041] The switch is arranged at a position where it can be operated using the hand that holds the housing 101.

[0042] In particular, the start switch circuit 131 preferably has a configuration that supplies a start signal when a plurality of switches operate. The plurality of switches (switch 132a, switch 132b, switch 132c and switch 132d) are distributed and arranged on the first surface 101a of the housing 101 and the second surface 101b facing the first surface 101a, etc. (see FIG. 1(C)).

[0043] The security device 100 includes a start switch circuit 131 that supplies a start signal based on the operation of a plurality of switches 1 32 distributed and arranged on a plurality of opposing surfaces of the housing 101. This makes it possible to prevent the start switch circuit 131 from operating due to an incorrect operation, as compared to a start switch circuit that operates by operating a single switch. As a result, it is possible to provide a novel security device with fewer incorrect operations. Or, it is possible to provide a novel information processing device that can preserve information useful for proving that a crime has occurred.

[0044] For example, switches 132a, 132b, 132c, and 132d are arranged in a portion of the housing 101 where the light emitting element 120 is not arranged. This enables a user (also referred to as a victim) who is unexpectedly attacked by a thug or the like (also referred to as a perpetrator) to surely emit light at an unexpected time. The element 120 can be directed towards a ruffian or the like. Or, the security device 100 can be easily operated to emit pulsed light.

[0045] Also, a switch 132t to which the end of the strap 132s is attached may be disposed in the housing 101. By gripping the housing 101 with one hand and pulling out the strap 132s with the other hand, the switch 132t can be configured to operate.

[0046] Also, the security device 100 can be configured to operate when a plurality of switches are operated. Thereby, it is possible to suppress the occurrence of a problem that the user of the security device accidentally operates the security device 100.

[0047] For example, the security device 100 can be configured to operate when a plurality of switches selected from the switches 132a, 132b, 132c, and 132d are operated. Or, the security device 100 can be configured to operate by pulling out the strap 132s with one hand while pressing any one of the switches with the other hand.

[0048] 《Start Switch Circuit》 The start switch circuit 131 can supply a start signal. The start switch circuit 131 includes a switch 132 and supplies high or low as a start signal during the period when the switch 132 is being operated (see FIG. 1(A)).

[0049] In addition, a control pulse signal can be supplied from the start switch circuit 131. For example, the start switch circuit 131 can be configured using a switch 132, a latch circuit, and a monostable multivibrator. ​

[0050] Specifically, a high or low signal is supplied to the latch circuit using the switch 132, and the latch circuit supplies a trigger signal, and the monostable multivibrator that has received the trigger signal supplies a rectangular wave having a predetermined width as a control pulse signal.

[0051] 《Pulse Interval Modulation Circuit》 The pulse interval modulation circuit 135 can supply a pulse interval modulation signal. For example, a varying voltage can be used as the pulse interval modulation signal using the variable resistor 136. The pulse interval can be set to such an extent that a person such as a hooligan can perceive the light emitted by the light emitting element 120 as pulsed light. Specifically, less than 60 Hz, preferably 20 Hz or less, and particularly preferably 5 Hz or less. Also, the interval may not be constant and may be irregular.

[0052] 《Microcomputer》 The microcomputer 137 receives a start signal and a pulse interval modulation signal, and can supply a control pulse signal and a shutter signal.

[0053] The microcomputer 137 includes an arithmetic unit CPU, a timer unit TIMER, an analog-to-digital converter ADC, an input / output unit I / O, a storage unit MEM, and a transmission path for transmitting

[0054] data signals. The input / output unit I / O receives a start signal and a pulse interval modulation signal, and can supply

[0055] a control pulse signal and a shutter signal. The analog-to-digital converter ADC converts an analog signal into a digital signal. For example,

[0056] The arithmetic unit CPU processes the supplied data according to the program stored in the storage unit MEM and supplies the processed data.

[0057] The timer unit TIMER can measure a predetermined time according to an instruction and supply a control pulse signal and a shutter signal approximately simultaneously after the elapse of the predetermined time. Or, it can supply repeatedly at every predetermined time.

[0058] The timer unit TIMER can measure the time for determining the width (half-value width) of the control pulse signal. For example, it can set a predetermined width of the control pulse signal to be 1 millisecond or more and 1000 milliseconds or less, preferably 10 milliseconds or more and 100 milliseconds or less.

[0059] Thus, the user can irradiate a thug or the like with pulsed light once or repeatedly using the security device to intimidate the thug or the like. As a result, the occurrence of a crime can be prevented. Also, the imaging unit 150 can capture an image when a crime occurs and preserve information useful for proving the occurrence of the crime.

[0060] The storage unit MEM stores a program to be executed by the arithmetic unit CPU.

[0061] For example, when the period during which the start signal is supplied is shorter than a predetermined time, the microcomputer 137 supplies the control pulse signal once.

[0062] Also, when the period during which the start signal is supplied is equal to or longer than a predetermined time, the microcomputer 137 supplies the control pulse signal and the shutter signal a plurality of times at intervals corresponding to the pulse interval modulation signal.

[0063] The number of control pulse signals and shutter signals supplied multiple times by the microcomputer 137 can be a predetermined number. Or, it can be the number that can be supplied during the period while the start signal is continuously supplied. Or, it can be the number that can be supplied during the period until the start signal that has once stopped is supplied again.

[0064] Note that the shutter signal may be supplied for each control pulse signal, or may be supplied for each predetermined number of control pulse signals or together with a predetermined number of control pulses.

[0065] Hereinafter, a configuration in which the control pulse signal can be continuously supplied intermittently until the start signal is supplied again will be described.

[0066] A high or low start signal is supplied to the standby microcomputer 137 using the switch 132. The microcomputer 137 supplies a rectangular wave having a predetermined width to the switching circuit 110 as a control pulse signal, and measures the time during which the start signal is supplied.

[0067] When the period during which the start signal is supplied is shorter than a predetermined time, the microcomputer 137 supplies the control pulse signal once and then returns to the standby state.

[0068] When the period during which the start signal is supplied is equal to or longer than a predetermined time, the microcomputer 137 determines a predetermined pulse interval according to a digital signal obtained by converting a pulse interval modulation signal, and intermittently supplies the control pulse signal at the predetermined pulse interval until the start signal is supplied again.

[0069] 《Constant current power supply》 ​​​​​​​​​The constant current power supply 140 includes a battery that supplies a first voltage and a power supply that supplies the first voltage and is higher than the first voltage. A first DC-DC converter supplies a second voltage higher than the first voltage, and a second voltage is supplied to the second DC-DC converter to store the charge. A capacitor that supplies the charge and a second DCDC capacitor that can supply a constant current. and a converter (see FIG. 2(A)).

[0070] The battery can be a primary battery or a secondary battery. Battery, lead acid battery, lithium ion battery, etc. can be applied.

[0071] Moreover, a plurality of batteries may be provided. One is used to take an image using the communication unit 190, and the other is used to transmit the image using the communication unit 190. This allows the light emission of the light emitting element 120 and the image capture using the image capture unit 150 to be performed simultaneously. When the battery of the camera is consumed, the communication unit 190 transmits the acquired image information and position information to the other camera. Transmission can be performed using a battery.

[0072] The other battery can be said to be for emergency use, and is used for communication using the communication unit 190 in an emergency. In particular, an electric double layer capacitor is preferable for the other battery.

[0073] The first DC-DC converter boosts the battery voltage (first voltage) to supply the second voltage. do.

[0074] The capacitor is charged with a second voltage.

[0075] The second DC-DC converter is supplied with the charge stored in the capacitor and supplies a constant current. do.

[0076] An example of the change over time of the current supplied by the constant current power supply 140 is shown in FIG. 2(B).

[0077] According to this configuration, while the capacitor supplies charge to the second DCDC converter , the second DCDC converter can supply a constant current. Note that when the charge stored in the capacitor falls below a predetermined amount, the second DCDC converter can no longer supply a constant current .

[0078] The constant current power supply 140 can supply a constant current for a time longer than at least the width of the control pulse signal supplied by the microcomputer 137 (for example 50 milliseconds).

[0079] Note that when current flows through the open / close circuit 110, the charge stored in the capacitor is consumed. As a result , the constant current power supply 140 can no longer continue to supply a constant current, and a current that is not a rectangular wave flows through the light emitting element 120. As a result, the light emitting element 120 emits light at a luminance lower than a predetermined luminance .

[0080] Light that is lower than a predetermined luminance and lacks glare is ineffective in intimidating thugs and the like, so the power is wasted .

[0081] Before the constant current power supply 140 becomes unable to supply a constant current, the open / close circuit 110 stops supplying current . This can suppress the consumption of unnecessary power. Note that an example of the current supplied by the open / close circuit 110 is shown in FIG. 2(C).

[0082] 《Control Circuit》 The magnitude of the current supplied by the constant current power supply 140 may be controlled according to the brightness of the environment in which the security device 100 is used , the distance to a thug or the like, or the usage history of the light emitting element (see FIG. 2(D) ).​

[0083] The security device 100 has a sensor that supplies a detection signal, and a control circuit 145 to which the detection signal is supplied and that supplies a control signal, and a constant current power supply 140 is supplied with the control signal and configured to supply a constant current of a magnitude corresponding to the control signal.

[0084] As a method for controlling the magnitude of the current supplied by the constant current power supply 140, the second DCDC converter may be controlled using the control signal.

[0085] Examples of the sensor that supplies the detection signal include a photosensor that detects the brightness of the environment in which the security device 100 is used or a distance sensor that detects the distance to a thug or the like. Specifically, a photodiode, an ultrasonic sensor, or the like can be applied.

[0086] Further, the degree of deterioration of the light emitting element 120 may be predicted using a storage circuit that stores the usage history of the light emitting element 120. The magnitude of the current supplied by the constant current power supply 140 may be controlled so as to compensate for the deterioration associated with the use of the light emitting element 120.

[0087] 《Closed - Open Circuit》 While a constant current and a control pulse signal are being supplied, the closed - open circuit 110 supplies a constant current pulse to the light emitting element 120.

[0088] For example, a power transistor can be applied to the closed - open circuit 110. Specifically, a control pulse signal is supplied to the gate of the power transistor, a constant current is supplied to the first electrode, and the light emitting element 120 is electrically connected to the second electrode to configure the closed - open circuit 110. For example, a current of 2 A can be supplied to the light emitting element 120 for 50 milliseconds.

[0089] ​​​​​​​​​ "Light-emitting Element" The light-emitting element 120 can use any of a point light source, a line light source, and a surface light source. For example, a light-emitting diode, a xenon lamp, an organic EL element, etc. can be applied to the light-emitting element 120.

[0090] The light-emitting element 120 may be used singly or plurally. Also, a light-emitting panel provided with a plurality of light-emitting elements on a single support substrate can also be used.

[0091] Also, a plurality of light-emitting elements may be used, and each light-emitting element may be configured to emit light of a different color. It may be such.

[0092] Also, a constant current circuit may be prepared for each color of the light-emitting elements presenting different colors, and the magnitude of the current supplied to each light-emitting element presenting different colors may be independently controlled.

[0093] Thereby, the color and color temperature of the emitted light can also be made variable. As a result, the imaging unit 15 0 can capture an image of the subject, environment, atmosphere, etc. with good reproduction.

[0094] Also, a flexible light-emitting panel using a flexible material for the support substrate or the like can be arranged along a housing having a curved surface. Thereby, the light-emitting device can be arranged without impairing the design of the housing. For example, a flash can be arranged along the housing having a curved surface of a camera.

[0095] An organic EL element can be applied to the light-emitting element 120. The security device 100 to which the organic EL element is applied can increase the light-emitting area of the light-emitting element 120 and make the security device 100 thin and light.

[0096] Note that the configuration of the light-emitting panel using the organic EL element will be described in detail in Embodiment 4, and the configuration of the organic EL element will be described in detail in Embodiment 5. The total area of the light-emitting portion of the light-emitting panel using the organic EL element is, for example, 0.5 cm

[0199] Note that the present embodiment can be appropriately combined with other embodiments shown in this specification. .

[0200] (Embodiment 4) In this embodiment, the configuration of a light emitting panel that can be used in a light emitting device according to an aspect of the present invention will be described with reference to FIGS. 8 to 11. It will be described with reference to FIGS. 8 to 11.

[0201] A light emitting device according to an aspect of the present invention can be used, for example, as a flash of a camera. Here, when the flash of the camera is made smaller, the light emitting part approaches a linear or dot shape. Since light travels straight from the light source, the shadow projected by one object becomes clearer as the light source becomes smaller. Accordingly, for example, when a person's face is photographed in a dark place using a flash, the shadow of the nose may be projected onto the cheek. Since light travels straight from the light source, the shadow projected by one object becomes clearer as the light source becomes smaller. Accordingly, for example, when a person's face is photographed in a dark place using a flash, the shadow of the nose may be projected onto the cheek. Accordingly, for example, when a person's face is photographed in a dark place using a flash, the shadow of the nose may be projected onto the cheek. There may be a case.

[0202] In addition, when the flash emits light that is stronger than necessary, portions that originally have different brightness levels may become white in the photograph (so-called white blooming). On the other hand, when the flash emits weak light There may be a case where the photograph becomes all white. On the other hand, when the flash emits weak light If it is too much, the dark part may become completely black in the photo (so-called black crush). Therefore, it is preferable that the flash can adjust the light amount depending on the environment and the situation of the subject.

[0203] Therefore, in one aspect of the present invention, a light-emitting element which is a surface light source is used for the light-emitting panel. For example, when an organic EL element is used, an element with a thin film thickness and a large area can be easily formed. When emitting the same amount of light, compared with a point light source or a line light source, the surface light source can reduce the light amount per unit area or can shorten the light emission time. Thereby, the heat generation amount per unit area can be reduced. In addition, since the light emission area is wide, it is easy to dissipate heat. Therefore, deterioration caused by local heat generation of the light-emitting panel can be suppressed. Compared with the case of using a light-emitting diode or the like using an inorganic material, the light-emitting panel has less deterioration, and a highly reliable light-emitting device can be provided.

[0204] In addition, when an organic EL element is used for the light-emitting panel, compared with the case of using a conventional xenon lamp or the like , the light-emitting panel can be made thinner and lighter. Further, since heat generation accompanying light emission is dispersed over a wide area of the light-emitting panel, heat is dissipated efficiently. Thereby, heat storage in the light-emitting panel is suppressed, and deterioration of the light-emitting panel is suppressed.

[0205] In addition, when the light-emitting panel is a surface light source, even if the light-emitting device of one aspect of the present invention is used as a camera flash , it is difficult for a shadow to occur on the subject.

[0206] By selecting and using a light-emitting organic compound, the light-emitting panel can be configured to emit light that exhibits white. For example, a plurality of light-emitting organic compounds that emit colors in a complementary color relationship with each other ​​A compound can be used. Alternatively, a light-emitting organic compound exhibiting red, green, and blue colors can be used. Also, various light-emitting spectra can be selected from various organic compounds and used. Thereby, a light-emitting device excellent in white balance can be obtained .

[0207] When a light-emitting organic compound is used, a wider emission spectrum can be obtained compared to a light-emitting diode using an inorganic material. Light having a wide emission spectrum is close to natural light and is suitable for photography.

[0208] Hereinafter, a configuration example of a light-emitting panel using an organic EL element as a light-emitting element will be described.

[0209] 《Configuration Example 1 of Light-Emitting Panel》 FIG. 8(A) is a plan view showing a light-emitting panel according to an aspect of the present invention, and FIG. 8(B) is a cross-sectional view taken along the dashed line A-B in FIG. 8( A).

[0210] The light-emitting panel shown in FIGS. 8(A) and 8(B) includes a light-emitting element 403 in a space 415 surrounded by a support substrate 401, a sealing substrate 405, and a sealing material 40 7. The light-emitting element 403 is an organic EL element having a bottom emission structure. Specifically, it has a first electrode 421 that transmits visible light on the support substrate 401, an EL layer 423 on the first electrode 421, and a second electrode 425 that reflects visible light on the EL layer 423. The light-emitting element applied to an aspect of the present invention is not limited to the bottom emission structure, and may be, for example, a top emission structure.

[0211] The first terminal 409a is electrically connected to the auxiliary wiring 417 and the first electrode 421. The first ...

[0212] ... On the electrode 421, an insulating layer 419 is provided in a region overlapping with the auxiliary wiring 417. The first terminal 409a and the second electrode 425 are electrically insulated by the insulating layer 419. The second terminal 409b is electrically connected to the second electrode 425. In this embodiment, although the configuration in which the first electrode 421 is formed on the auxiliary wiring 417 is shown, the auxiliary wiring 417 may be formed on the first electrode 421.

[0213] It is preferable to have a light extraction structure 411a at the interface between the support substrate 401 and the atmosphere. By providing the light extraction structure 411a at the interface between the atmosphere and the support substrate 401, light that cannot be extracted into the atmosphere due to the effect of total reflection can be reduced, and the light extraction efficiency of the light-emitting panel can be improved.

[0214] Also, it is preferable to have a light extraction structure 411b between the light-emitting element 403 and the support substrate 401. When the light extraction structure 411b has irregularities, it is preferable to provide a planarization layer 413 between the light extraction structure 411b and the first electrode 421. Thereby, the first electrode 421 can be made into a flat film, and the generation of leakage current caused by the irregularities of the first electrode 421 in the EL layer 423 can be suppressed. Further, since the light extraction structure 411b is provided at the interface between the planarization layer 413 and the support substrate 401, light that cannot be extracted into the atmosphere due to the effect of total reflection can be reduced, and the light extraction efficiency of the light-emitting panel can be improved.

[0215] As materials for the light extraction structure 411a and the light extraction structure 411b, for example, resin can be used. Also, as the light extraction structure 411a and the light extraction structure 411b, a hemispherical lens, a microlens array, a film with an uneven structure, a light diffusion film, etc. ​​​​​​​​​​​ can also be used. For example, the above lens and film are adhered onto the support substrate 401 using the support substrate 401 or an adhesive having a refractive index similar to that of the lens or film, etc., to form the light extraction structure 411a and the light extraction structure 411b. .

[0216] The planarization layer 413 is flatter on the surface in contact with the first electrode 421 than on the surface in contact with the light extraction structure 411b. As the material of the planarization layer 413, a material having light transmissibility and a high refractive index (for example, a liquid material such as a refractive liquid, glass, resin, etc.) can be used.

[0217] Note that the light-emitting panel according to one aspect of the present invention can also be configured without providing a light extraction structure. In that case, it is possible and preferable to use the second electrode that reflects visible light as a mirror.

[0218] <<Configuration Example 2 of Light-Emitting Panel>> FIG. 9(A) is a plan view showing a light-emitting panel according to one aspect of the present invention, and FIGS. 10(A) and 10(B) are cross-sectional views obtained by cutting FIG. 9(A) along the dashed-dotted line X1 - Y1, respectively.

[0219] In the light-emitting panel shown in FIG. 10(A), a light-emitting element 1250 is provided on a support substrate 1220 via an insulating film 1224. An auxiliary wiring 1206 is provided on the insulating film 1224 and is electrically connected to the first electrode 1201. A part of the auxiliary wiring 1206 is exposed and functions as a terminal. The end portions of the first electrode 1201 and the conductive layer 1210 are covered by a partition wall 1205. Also, a partition wall 1205 is provided to cover the auxiliary wiring 1206 via the first electrode 1201. The light-emitting element 1250 is composed of a support substrate 1220, a sealing substrate 1228, and ​​​​​​​It is sealed by a sealing material 1227. On the surface of the support substrate 1220, a light extraction structure 12 09 is bonded. By using a flexible substrate for the support substrate 1220 and the sealing substrate 1228, a flexible light-emitting panel can be realized.

[0220] The light-emitting element 1250 is an organic EL element with a bottom emission structure. Specifically, it has a first electrode 1201 that transmits visible light on the support substrate 1220, an EL layer 1202 on the first electrode 1201, and a second electrode 1203 that reflects visible light on the EL layer 1202.

[0221] In the light-emitting panel shown in FIG. 10(B), instead of the support substrate 1 220 and the light extraction structure 1209 shown in FIG. 10(A), a support substrate 122 9 having a light extraction structure is provided. The support substrate 1229 has both the function as a support and the function of improving the light extraction efficiency of the light-emitting panel.

[0222] Here, when manufacturing a flexible light-emitting panel, as a method of forming a light-emitting element on a flexible substrate, for example, a first method of directly forming a light-emitting element on a flexible substrate, and a method of forming a light-emitting element on a substrate with high heat resistance different from the flexible substrate (hereinafter referred to as a manufacturing substrate), and then peeling the manufacturing substrate and the light-emitting element and transferring the light-emitting element to the flexible substrate, there are the second methods.

[0223] For example, when using a substrate having heat resistance against the temperature applied in the manufacturing process of the light-emitting element, such as a glass substrate having a thickness as thin as the degree of flexibility, using the first method is preferred because the process is simplified.

[0224] ​​​​​​​ Also, by applying the second method, a low-permeability insulating film or the like formed on the production substrate can be transferred to a flexible substrate. Therefore, even if an organic resin or the like with high water permeability and low heat resistance is used as the material of the flexible substrate, a light-emitting panel with flexibility and high reliability can be produced.

[0225] 《Configuration Example 3 of Light-Emitting Panel》 FIG. 9(B) is a plan view showing a light-emitting panel according to an aspect of the present invention, and FIGS. 11(A) and (B) are examples of cross-sectional views obtained by cutting FIG. 9(B) along the dashed-dotted line X2 - Y2, respectively, and FIG. 11(C ) is a cross-sectional view obtained by cutting FIG. 9(B) along the dashed-dotted line X3 - Y3.

[0226] The light-emitting panel shown in FIGS. 11(A) to (C) is different from Configuration Example 2 of the light-emitting panel in that it has openings in part. Here, only the differences will be described in detail, and for the common points, the description of Configuration Example 2 of the light-emitting panel will be referred to.

[0227] As shown in FIGS. 11(A) and (B), the light-emitting panel preferably has a sealing material 1226 at the opening so that the electrodes and the EL layer are not exposed. Specifically, after opening a part of the light-emitting panel, the sealing material 1226 may be formed so as to cover at least the exposed electrodes and the EL layer. The same material as that of the sealing material 1227 can be used for the sealing material 1226, and it may be the same material or different materials.

[0228] FIG. 11(A) shows an example of the case where an opening is made at a position where the partition wall 1205 is not formed, and FIG. 11(B) shows an example of the case where an opening is made at a position where the partition wall 1205 is formed.

[0229] By manufacturing such a light-emitting panel and arranging the camera lens so as to overlap with the opening portion , a light-emitting portion can be arranged around the camera lens. Then, the light-emitting portion can be used as the camera flash.

[0230] Note that a light extraction structure may be provided on the surface of the substrate.

[0231] 《Materials of the Light-Emitting Panel》 An example of a material that can be used for the light-emitting panel according to an aspect of the present invention will be described.

[0232] [Substrate] For the substrate on the side where the light from the light-emitting element is extracted, a material that transmits the light is used. For example, materials such as glass , quartz, ceramic, sapphire, and organic resin can be used.

[0233] By using a substrate with a thin film thickness, the weight reduction and thinning of the light-emitting panel can be achieved. Further , by using a substrate with a thickness that has flexibility, a flexible light-emitting panel can be realized . Also, when a flexible light-emitting panel is not used, it can be folded and stored . Thus, instead of a reflect board (board d reflector) that can be used in a photo studio, it can be used as an illumination device that emits flash light over a wide area . Or, an illumination device that can be folded can be provided.

[0234] As the glass, for example, non-alkali glass, barium borosilicate glass, aluminoboro silicate glass, etc. can be used.

[0235] Examples of materials having flexibility and transparency to visible light include those having a degree of flexibility Thick glass, polyester resins such as polyethylene terephthalate (PET) and polyethylene naphthalate ( PEN), polyacrylonitrile resin, polyimide resin, polymethyl methacrylate resin, polycarbonate (PC) resin, polyethersulfone (PES ) resin, polyamide resin, cycloolefin resin, polystyrene resin, polyamideimide resin, polyvinyl chloride resin, etc. can be mentioned. In particular, it is preferable to use a material with a low coefficient of thermal expansion. For example, polyamideimide resin, polyimide resin, PET, etc. can be suitably used. Also, a substrate in which glass fibers are impregnated with an organic resin, or a substrate in which an inorganic filler is mixed with an organic

[0236] resin to reduce the coefficient of thermal expansion can be used. A substrate using such a material is light in weight, so a light-emitting panel using this substrate can also be made lightweight. Also, since the substrate on the side where light emission is not extracted does not need to have translucency, in addition to the substrates

[0237] mentioned above, a metal substrate using a metal material or an alloy material can also be used. Metal materials and alloy materials have high thermal conductivity and can easily

[0238] conduct heat to the entire sealing substrate, so it is possible toAlternatively, a substrate subjected to insulation treatment may be used, such as by oxidizing the surface of a conductive substrate or forming an insulating film on the surface. For example, an insulating film may be formed using a coating method such as spin coating or dip coating, electrodeposition, vapor deposition, or sputtering. In addition to leaving it in an oxygen atmosphere or heating it, an oxide film may be formed on the surface of the substrate by anodization or the like. As the flexible substrate, a layer using the above materials may be laminated with a hard coat layer (for example, a silicon nitride layer, etc.) that protects the surface of the light-emitting panel from scratches, or a layer made of a material capable of dispersing pressure (for example, an aramid resin layer, etc.). Further, in order to suppress a decrease in the life of the light-emitting element due to moisture or the like, a film containing nitrogen and silicon such as a silicon nitride film or a silicon oxynitride film, or a film containing nitrogen and aluminum such as an aluminum nitride film, etc., having a low water permeability insulating film may be provided.

[0239] The substrate may be used by laminating a plurality of layers. In particular, if it has a glass layer structure, the barrier properties against water and oxygen can be improved, and a highly reliable light-emitting panel can be obtained. For example, a substrate having a glass layer, an adhesive layer, and an organic resin layer laminated from the side closer to the light-emitting element can be used. The thickness of the glass layer is 20 μm or more and 200 μm or less, preferably 25 μm or more and 100 μm or less. A glass layer having such a thickness can simultaneously achieve high barrier properties against water and oxygen and flexibility. In addition, the thickness of the organic resin layer is 10 μm or more

[0240] and 200 μm or less, preferably 20 μm or more and 50 μm or less. Such an organic resin layer

[0241] ​​​​​​By providing it outside the glass layer, cracks and fractures in the glass layer can be suppressed, and mechanical strength can be improved. By applying such a composite material of a glass material and an organic resin to a substrate, a highly reliable flexible light-emitting panel can be obtained.

[0242] [Insulating film] An insulating film may be formed between the support substrate and the light-emitting element. As the insulating film, an inorganic insulating film such as a silicon oxide film, a silicon nitride film, a silicon oxynitride film, or a silicon nitride oxide film can be used. In particular, in order to suppress the intrusion of moisture and the like into the light-emitting element, it is preferable to use an insulating film with low water permeability such as a silicon oxide film, a silicon nitride film, or an aluminum oxide film. For the same purpose and using the same material, an insulating film covering the light-emitting element may be provided.

[0243] [Partition wall] As the partition wall, an organic resin or an inorganic insulating material can be used. As the organic resin, for example, , a polyimide resin, a polyamide resin, an acrylic resin, a siloxane resin, an epoxy resin, or a phenol resin can be used. As the inorganic insulating material, silicon oxide, silicon oxynitride, etc. can be used. Since it is easy to fabricate the partition wall, it is particularly preferable to use a photosensitive resin.

[0244] The method for forming the partition wall is not particularly limited, and for example, a photolithography method, a sputtering method, a vapor deposition method, a droplet discharge method (inkjet method, etc.), a printing method (screen printing, offset printing, etc.) can be used.

[0245] [Auxiliary wiring] The auxiliary wiring does not necessarily need to be provided, but it is preferably provided in order to suppress the voltage drop caused by the resistance of the electrode. ​​​​

[0246] The material of the auxiliary wiring is selected from copper (Cu), titanium (Ti), tantalum (Ta), tungsten (W ), molybdenum (Mo), chromium (Cr), neodymium (Nd), scandium (Sc), nickel (Ni), or an alloy material mainly composed of these materials, and is formed as a single layer or by lamination. Aluminum can also be used as the material of the auxiliary wiring. However, in that case, a laminated structure should be adopted so that the above-mentioned corrosion problem does not occur, and aluminum can be used in a layer that does not contact ITO or the like. The film thickness of the auxiliary wiring can be 0.1 μm or more and 3 μm or less, preferably 0.1 μm or more and 0.5 μm or less.

[0247] [Sealing material] The sealing method of the light-emitting panel is not limited. For example, it can be solid sealing or hollow sealing. For example, glass materials such as glass frit, curable resins that cure at room temperature such as two-component mixed resins, photo-curable resins, thermosetting resins and other resin materials can be used. The light-emitting panel may be filled with an inert gas such as nitrogen or argon, and may be filled with a resin such as PVC (poly vinyl chloride) resin, acrylic resin, polyimide resin, epoxy resin, silicone resin, PVB (polyvinyl butyral) resin, EVA (ethylene vinyl acetate) resin, etc. Moreover, a desiccant may be contained in the resin.

[0248] [Light extraction structure] As the light extraction structure, a hemispherical lens, a microlens array, a film with an uneven structure applied thereto, a light diffusion film, etc. can be used. For example, the above-mentioned lens or film is provided on the substrate. By bonding using an adhesive or the like having a refractive index similar to that of the substrate, the lens, or the film, a light extraction structure can be formed. By bonding using an adhesive or the like having a refractive index similar to that of the substrate, the lens, or the film, a light extraction structure can be formed.

[0249] Since the light-emitting panel of this embodiment is a surface light source, by applying it to a light-emitting device, a light-emitting device that is less likely to cause shadows on the subject even when used as a flash can be provided. Also, compared to the case of using a light-emitting diode or the like using an inorganic material, even when emitting a large amount of light, the deterioration of the light-emitting panel is small, and a highly reliable light-emitting device can be provided. Further, compared to the case of using a xenon lamp or the like, miniaturization and thinning of the light-emitting device can be achieved. Since the light-emitting panel of this embodiment is a surface light source, by applying it to a light-emitting device, a light-emitting device that is less likely to cause shadows on the subject even when used as a flash can be provided. Also, compared to the case of using a light-emitting diode or the like using an inorganic material, even when emitting a large amount of light, the deterioration of the light-emitting panel is small, and a highly reliable light-emitting device can be provided.

Also, compared to the case of using a light-emitting diode or the like using an inorganic material, even when emitting a large amount of light, the deterioration of the light-emitting panel is small,

[0250] Note that this embodiment can be appropriately combined with other embodiments described in this specification.

[0251] (Embodiment 5) In this embodiment, a light-emitting element that can be used in a light-emitting device according to one aspect of the present invention will be described with reference to FIG. 12.

[0252] <<Configuration Example of Light-Emitting Element>> The light-emitting element shown in FIG. 12(A) has an EL layer 2203 between a first electrode 2201 and a second electrode 2205. In this embodiment, the first electrode 2201 functions as an anode, and the second electrode 2205 functions as a cathode.

[0253] When a voltage higher than the threshold voltage of the light-emitting element is applied between the first electrode 2201 and the second electrode 2205, holes are injected into the EL layer 2203 from the side of the first electrode 2201, and electrons are injected from the side of the second electrode 22 05. The injected electrons and holes recombine in the EL layer 2203, and the light-emitting substance contained in the EL layer 2203 emits light. and the light-emitting substance contained in the EL layer 2203 emits light.

[0254] The EL layer 2203 includes at least a light-emitting layer 2303 containing a light-emitting substance.

[0255] In addition, the EL layer 2203 is formed of a material having a high hole injection property, a material having a high hole transport property, and a layer other than the light emitting layer. A material with high electron transport properties, a material with high electron injection properties, or a bipolar material (electron The EL layer 22 may further include a layer containing a substance having high electron transporting and hole transporting properties. 03 can be used with either low molecular weight compounds or high molecular weight compounds, and inorganic compounds can also be used. It may include.

[0256] The light-emitting element shown in FIG. 12B has an EL element between a first electrode 2201 and a second electrode 2205. The EL layer 2203 includes a hole injection layer 2301, a hole transport layer 2302, The light-emitting layer 2303, the electron transport layer 2304, and the electron injection layer 2305 are disposed on the first electrode 2201. The layers are stacked in this order from the side.

[0257] As shown in FIG. 12C and FIG. 12D, the light-emitting element includes a first electrode 2201 and a second electrode 220. 5, a plurality of EL layers may be laminated between the EL layers. In this case, It is preferable to provide an intermediate layer 2207. The intermediate layer 2207 is a layer that covers at least the charge generating region. Yes.

[0258] For example, the light-emitting element shown in FIG. 12C includes a first EL layer 2203a and a second EL layer 220 12(D) has an intermediate layer 2207 between the EL layer 3b and the light-emitting element 2202. The EL element has n layers (n is a natural number of 2 or more), and an intermediate layer 2207 is provided between each EL layer.

[0259] In the intermediate layer 2207 provided between the EL layer 2203(m) and the EL layer 2203(m+1), Describe the behavior of electrons and holes. When a voltage higher than the threshold voltage of the light-emitting element is applied between the first electrode 2201 and the second electrode 2205 holes and electrons are generated in the intermediate layer 2207. The holes move to the EL layer 2203(m + 1) provided on the side of the second electrode 2205 and the electrons move to the EL layer 2203(m) provided on the side of the first electrode 2201. The holes injected into the EL layer 2 2203(m + 1) recombine with the electrons injected from the side of the second electrode 2205, and the light-emitting substance contained in the EL layer 2203(m + 1) emits light. Also, the electrons injected into the EL layer 22 03(m) recombine with the holes injected from the side of the first electrode 2201, and the light-emitting substance contained in the EL layer 2203(m) emits light. Therefore, the holes and electrons generated in the intermediate layer 2207 each reach light emission in different EL layers. When the EL layers are provided in contact with each other and the same configuration as the intermediate layer is formed between them the EL layers can be provided in contact with each other without passing through the intermediate layer. For example, when a charge generation region is formed on one

[0260] surface of the EL layer, an EL layer can be provided in contact with that surface. Also, by making the emission colors of the respective EL layers different, light emission of a desired color can be obtained for the entire light-emitting element. For example, in a light-emitting element having two EL layers, by making the emission color of the first

[0261] EL layer and the emission color of the second EL layer be complementary to each other, it is also possible to obtain a light-emitting element that emits white light as a whole. The same applies to a light-emitting element having three or more EL layers as well. For example, in a light-emitting element having two EL layers, by making the emission color of the first EL layer and the emission color of the second EL layer be complementary to each other, it is possible to obtain a light-emitting element that emits white light as a whole. The same applies to a light-emitting element having three or more EL layers as well. Also, in the case of a light-emitting element having three or more EL layers, the same applies.

[0270] In addition, polymer compounds such as poly(N-vinylcarbazole) (abbreviation: PVK), poly(4-vinyltriphenyl amine) (abbreviation: PVTPA), and polymer compounds added with acids such as poly(3,4-ethylenedioxythiophene) / poly(styrenesulfonic acid) (PEDOT / PSS) can be used.

[0271] In addition, the hole injection layer 2301 can also be used as the charge generation region. When the hole injection layer 23 01 in contact with the anode is the charge generation region, various conductive materials can be used for the anode without considering the work function. It is possible. The materials constituting the charge generation region will be described later.

[0272] 〈Hole transport layer 2302〉 The hole transport layer 2302 is a layer containing a substance with high hole transport properties.

[0277] Note that the light-emitting layer 2303 may have a structure in which the above-described light-emitting organic compound (light-emitting substance, guest material) is dispersed in another substance (host material). As the host material, various materials can be used, and it is preferable to use a substance having a higher lowest unoccupied molecular orbital level (LUMO level) and a lower highest occupied molecular orbital level (HOMO level) than the guest material.

The light-emitting portion 7303 of the light-emitting device 7310 is arranged so as to surround the lens 7304. Since the light-emitting device according to an aspect of the present invention has flexibility, it can be bent. In the digital still camera 7300, since the non-light-emitting portion 7 305 is bent along the shape of the housing 7301, the light-emitting portion 7303 can be widely arranged around the lens 7304.

It is shown in FIG. 13(C). It is shown in FIG. 13(C).

[0297] The mobile phone 7350 includes a housing 7351, a display unit 7352, a lens 7354, a light-emitting device 73 60, etc. The light-emitting device 7360 applies the light-emitting device according to one aspect of the present invention. The light-emitting device 7360 has a light-emitting portion 7353 and a non-light-emitting portion 7355, and the light-emitting portion 7353 is arranged so as to surround the lens 7354.

[0300] Signals corresponding to the conditions selected by the user of the mobile phone 7350 and detection signals from various sensors are supplied to the two control devices 750a, 750b. The two control devices 750a, 7 50b respectively supply control signals according to the supplied signals. 50b respectively supply control signals according to the supplied signals.

[0301] The constant current power supply 740a supplies a constant current pulse according to the control signal supplied from the control device 750a. to the light emitting panel 7353a. The constant current power supply 740b supplies a constant current pulse according to the control signal supplied from the control device 750b to the light emitting panel 7353b. Therefore, the light amounts of the two light emitting panels 7353a and 7353b are independently adjusted. As a result, the light amount emitted by the light emitting device can be adjusted in a wider range, which is preferable.

[0302] Also, light emitting panels having different colors and color temperatures may be used. For example, when the color temperatures of the two light emitting panels are different, the light emitting device can emit light with an appropriate color temperature by adjusting the light amounts of the respective light emitting panels.

For example, if only the light emission of one light emitting panel is sufficient, ​​In some cases, only one of the light-emitting panels emits light, and both light-emitting panels emit light only when a larger amount of light is required. This can suppress the power consumption of the light-emitting device and the deterioration of the light-emitting panel.

[0306] FIG. 14(B) shows an example of a bicycle. The bicycle 7400 has a light 7405. The light 7405 is applied with a light-emitting device according to an aspect of the present invention.

[0307] FIG. 14(C) shows an example of an automobile. The automobile 7410 has a light 7415. The light 7415 is applied with a light-emitting device according to an aspect of the present invention.

[0308] When the light-emitting device according to an aspect of the present invention is used for the lights of a bicycle or an automobile, for example, a light sensor is used to detect the ambient brightness. When the surroundings are bright enough, the light is not turned on. When the surroundings are dark enough, the light blinks. When the ambient brightness is insufficient but light can be detected, the light blinks and the amount of light is increased. Controls such as these can be performed. In this way, the light-emitting device according to an aspect of the present invention can emit light by appropriately adjusting to an optimal light amount, so that a power-saving light can be realized.

Specifically, it has a first electrode 1201 that transmits visible light on the support substrate 1229, has an EL layer 1202 on the first electrode 1201, and has a second electrode 1203 that reflects visible light on the EL layer 1202. plate 1229, has a first electrode 1201 that transmits visible light, has an EL layer 1202 on the first electrode 1201, and has a second electrode 1203 that reflects visible light on the EL layer 1202. plate 1229, has a first electrode 1201 that transmits visible light, has an EL layer 1202 on the first electrode 1201, and has a second electrode 1203 that reflects visible light on the EL layer 1202. .

[0315] A method for manufacturing the light-emitting panel of this embodiment will be described.

[0316] First, a base film, a release layer (tungsten film), and a layer to be released were formed in this order on a glass substrate which is a production substrate. In this embodiment, the layer to be released includes an insulating film 1224, an auxiliary wiring 1206, , a first electrode 1201, and a partition wall 1205.

[0317] A total of seven auxiliary wirings 1206 were formed on the insulating film 1224. At this time, the pitch of the auxiliary wiring 1206 was set to 5.3 mm, and the width L2 was set to 322 μm. As the first electrode 1201, a metal oxide (ITSO) film containing silicon, indium, and tin was formed. The partition wall 1205 covering the auxiliary wiring 1206 was formed in a total of seven so that the width L1 was 330 μm.

[0318] Next, a temporary support substrate and the first electrode 1201 were adhered using an adhesive for peeling, and the layer to be released was peeled from the production substrate using the release layer. As a result, the layer to be released was provided on the temporary support substrate side.

[0319] Subsequently, the support substrate 1229 was bonded to the layer to be released from which the production substrate was peeled and the insulating film 1224 was exposed, using an ultraviolet curable adhesive. As the support substrate 1229, as described above, a diffusion film of a polyester resin was used. Then, the temporary support substrate was peeled off, and the first electrode 1201 was exposed on the support substrate 1229.

[0320] Next, an EL layer 1202 and a second electrode 1203 were formed on the first electrode 1201. The EL layer 1202 has a first EL layer having a light emitting layer containing a fluorescent compound exhibiting blue light emission, an intermediate layer, and a light emitting layer containing a phosphorescent compound exhibiting green light emission, from the first electrode 1201 side. A second EL layer having a layer and a light-emitting layer containing a phosphorescent compound exhibiting red light emission was laminated in this order. Silver was used for the second electrode 1203.

[0321] Next, a photocurable resin containing zeolite as the sealing material 1227 was applied and cured by irradiating with ultraviolet light. Then, using an ultraviolet curable adhesive, the support substrate 1229 and the sealing substrate 1228, which is a thin glass layer and a polyethylene terephthalate (PET) layer substrate, were bonded together.

[0322] Measurements were made on the operating characteristics of the light-emitting panel obtained as described above. The voltage-luminance characteristics of the light-emitting panel at this time are shown as "initial" in the legend of FIG. 16. Also, the emission spectrum of the light-emitting panel is shown in FIG. 17. As shown in FIG. 17, the light-emitting panel of this example exhibits an emission spectrum that includes light derived from each of a fluorescent compound exhibiting blue light emission, a phosphorescent compound exhibiting green light emission, and a phosphorescent compound exhibiting red light emission. It was found that

[0323] Thereafter, a reliability test of the light-emitting device using the light-emitting panel was conducted. As the reliability test, the light-emitting panel was made to emit light 3000 times or 10000 times at intervals. For each emission, a current of 2 A was passed through the light-emitting panel for 50 milliseconds (ms). The current density of the light-emitting element at this time corresponds to 90 m A / cm 2 The interval between emissions (time of non-emission) was set to 10 seconds.

[0324] FIG. 16 shows the voltage-luminance characteristics of the light-emitting panel after emitting light 3000 times and after emitting light 10000 times.

[0325] From FIG. 16, the voltage-luminance characteristics of the light-emitting panel, even after emitting light 10000 times, are the same as before the reliability test.​​​​​​ Almost no change was observed, and degradation of the light-emitting panel was not seen. From this, the high reliability of the light-emitting panel of this example was shown.

Example

[0326] In this example, an organic EL element applicable to one aspect of the present invention will be described.

[0327] In this example, it was investigated how much current could be passed through an organic EL element that exhibits white light emission. The light-emitting area of the used organic EL element was 2 mm × 2 mm. For each light emission, a current was passed through the organic EL element for 50 milliseconds (ms).

[0328] As a result, a current of 60 mA could be passed through the organic EL element (corresponding to a current density of 1500 mA / cm 2 ). However, when a current of 68 mA was passed (corresponding to a current density of 1700 mA / cm 2 ), the organic EL element short-circuited. )

[0329] From this, in a light-emitting device of one aspect of the present invention to which an organic EL element is applied, it was suggested that the light amount can be adjusted within a range where the current density is less than 17 00 mA / cm 2 . From this, it is considered that a larger current can be passed through the organic EL element compared to a light-emitting diode using an inorganic material, etc.

Example

[0330] In this example, a light-emitting device of one aspect of the present invention will be described.

[0331] FIG. 18 is a block diagram for explaining the configuration of a light-emitting device of one aspect of the present invention.

[0332] The light-emitting device 104 described in this embodiment includes an on-off circuit 110, a light-emitting panel 120p, a drive circuit 130, and a constant-current power supply 140. The drive circuit 130 includes a microcomputer 137, a start switch circuit 133a, and a pulse-width modulation circuit 135. Note that each component is considered in reference to the description of the above embodiment 1.

[0333] Specifically, the on-off circuit 110 of this embodiment intermittently supplies a constant-current pulse with a current magnitude of 2 A and a width of 50 milliseconds to the light-emitting panel 120p at intervals of 0.5 seconds or more and 5 seconds or less.

[0334] A plan view of the light-emitting panel fabricated in this embodiment is shown in FIG. 9(B), a cross-sectional view between the dashed-dotted line X2 - Y2 in FIG. 9(B) is shown in FIG. 11(A), and a cross-sectional view between the dashed-dotted line X3 - Y3 is shown in FIG. 11 (C). Note that in FIG. 9(B), a part of the configuration of the light-emitting panel is shown with omission. (C).

[0335] In the light-emitting panel of this embodiment, a light-emitting element 125 0 is provided on a support substrate 1220 with an insulating film 1224 interposed therebetween. An auxiliary wiring 1206 is provided on the insulating film 1224 and is electrically connected to the first electrode 1201. A part of the auxiliary wiring 1206 is exposed and functions as a terminal. The end portions of the first electrode 1201 and the conductive layer 1210 are covered with a partition wall 1205 . Further, a partition wall 1205 that covers the auxiliary wiring 1206 via the first electrode 1201 is provided . The light-emitting element 1250 is sealed by the support substrate 1220, a sealing substrate 1228, and a sealing material 12 27.

[0336] In the light-emitting panel of this embodiment, a diffusion film of a polyester-based resin is used as the support substrate 1220, and a thin glass layer and polyethylene terephthalate (PET are used as the sealing substrate 1228. ​​A substrate having layers was used. These substrates are flexible, and the light-emitting panel of this embodiment is a flexible light-emitting panel. Note that the support substrate 1220 of this embodiment can be said to have a light extraction structure .

[0337] In the light-emitting region of the light-emitting panel of this embodiment, out of 50 mm × 52.9 mm, it is the region excluding a circular non-light-emitting region with a diameter of 20 m m. The non-light-emitting region includes the opening of the light-emitting panel . The non-light-emitting region does not have the auxiliary wiring 1206 and the first electrode 1201 (refer to FIG. 11( A)). Thereby, when providing the opening, it is possible to prevent the first electrode 1201 of the light-emitting element 1250 and the auxiliary wiring 1206 from coming into contact with the second electrode 1203 and short-circuiting.

[0338] The light-emitting element 1250 is an organic EL element having a bottom emission structure. Specifically, it has a first electrode 1201 that transmits visible light on the support substrate 1220, has an EL layer 1202 on the first electrode 1201, and has a second electrode 1203 that reflects visible light on the EL layer 1202 . .

[0339] A method for manufacturing the light-emitting panel of this embodiment will be described.

[0340] First, a base film, a release layer (tungsten film), and a layer to be peeled off were formed in this order on a glass substrate which is a manufacturing substrate. In this embodiment, the layer to be peeled off includes an insulating film 1224, an auxiliary wiring 1206 , a first electrode 1201, and a partition wall 1205. .

[0341] A total of 125 auxiliary wirings 1206 were formed on the insulating film 1224. At this time, the pitch of the auxiliary wiring 1206 was set to 420 μm, and the width L2 was set to 3 μm. The first electrode As 1201, a metal oxide (ITSO) film containing silicon, indium, and tin was formed. A partition wall 1205 covering the auxiliary wiring 1206 was formed in a total of 125 pieces so that the width L1 was 6 μm. Since the width of the auxiliary wiring is as narrow as 3 μm, in the light-emitting panel of this embodiment, the auxiliary wiring is difficult to be visually recognized during light emission.

[0342] Next, a temporary support substrate and the first electrode 1201 were adhered using an adhesive for peeling, and the release layer was used to peel the layer to be peeled from the production substrate. As a result, the layer to be peeled was provided on the temporary support substrate side.

[0343] Subsequently, the support substrate 1220 was bonded to the layer to be peeled that was peeled from the production substrate and had the insulating film 1224 exposed, using an ultraviolet-curable adhesive. As the support substrate 1220, as described above, a diffusion film of a polyester-based resin was used. Then, the temporary support substrate was peeled off, and the first electrode 1201 was exposed on the support substrate 1229.

[0344] Next, an EL layer 1202 and a second electrode 1203 were formed on the first electrode 1201. The EL layer 1202 includes, from the first electrode 1201 side, a first EL layer having a light-emitting layer containing a fluorescent compound that exhibits blue light emission, an intermediate layer, and a second EL layer having a light-emitting layer containing a phosphorescent compound that exhibits green light emission and a light-emitting layer containing a phosphorescent compound that exhibits orange light emission, which are stacked in this order. Silver was used for the second electrode 1203.

[0345] Next, an ultraviolet-curable resin containing zeolite as the encapsulant 1227 was applied and cured by irradiating with ultraviolet light. Then, using an ultraviolet-curable adhesive, the support substrate 1220 and the encapsulation substrate 1228, which has a thin glass layer and a polyethylene terephthalate (PET) layer, were used.​​​​​​​ A substrate was bonded thereto.

[0346] Then, a circular opening was provided so as to overlap a non-light-emitting region surrounded by a light-emitting region. In this embodiment, A part of the light-emitting panel was opened using a laser (UV laser) having a wavelength in the ultraviolet region. As a mechanism for providing the opening, not only a laser but also a punch or the like can be mentioned. When opening with a punch or the like, film peeling (especially film peeling of the EL layer 1202 or the like) may occur due to the light-emitting panel being pressed. By opening with a laser, film peeling can be suppressed, and a highly reliable light-emitting panel can be manufactured, which is preferable. Then, the end portion of the light-emitting panel exposed by providing the opening was covered using an ultraviolet curable adhesive, and a sealing material 1226 was provided. The operating characteristics of the light-emitting panel obtained as described above were measured. The voltage-luminance characteristics of the light-emitting panel at this time are shown as "initial" in the legend of FIG. 19. Also, the emission

[0347] spectrum of the light-emitting panel is shown in FIG. 20. As shown in FIG. 20, the light-emitting panel of this embodiment exhibits an emission spectrum including light derived from a fluorescent compound exhibiting blue emission, a phosphorescent compound exhibiting green emission, and a phosphorescent compound exhibiting orange emission. respectively.

[0348] The light-emitting panel 120p emits light at a luminance of approximately 100,000 cd / m when a current of 2 A is supplied. Then, a reliability test of the light-emitting device using the light-emitting panel was performed. As the reliability test, the light-emitting panel was caused to emit light 50,000 times at intervals. For each emission, a current of 2 A was applied to the light-emitting panel.

[0349] Note that the light-emitting panel 120p emits light at a luminance of approximately 100,000 cd / m 2 when a current of 2 A is supplied.

[0350] Thereafter, a reliability test of the light-emitting device using the light-emitting panel was performed. As the reliability test, the light-emitting panel was caused to emit light 50,000 times at intervals. For each emission, a current of 2 A was applied to the light-emitting panel. ​​​​was passed for 50 milliseconds (ms). The current density of the light-emitting element at this time was 87 mA / cm 2 corresponds to . Also, the interval between light emissions (time of non-light emission) was set to 0.5 seconds (s).

[0351] Fig. 19 shows the voltage-luminance characteristics of the light-emitting panel after it has emitted light 50,000 times.

[0352] From Fig. 19, it can be seen that the voltage-luminance characteristics of the light-emitting panel hardly changed even after it had emitted light 50,000 times, and no deterioration of the light-emitting panel was observed. Even when the light-emitting panel 120p was blinked 50,000 times at intervals of 0.5 seconds for a length of 50 milliseconds, the actual lighting time of the light-emitting panel 120p was only about 40 minutes, and it was shown that the heat generation associated with light emission had little effect on the light-emitting panel.

[0353] The light-emitting device 104 described in this embodiment has a light-emitting panel 120p using an organic EL element. Thereby, the light-emitting part can be spread in a planar shape. As a result, a small-sized light-emitting device can be provided.

[0354] Also, the light-emitting panel 120p can be made lighter, thinner, and have a larger area compared to other light-emitting elements (for example, LEDs). Thereby, the ratio of the light-emitting panel occupying the field of view can be easily increased.

[0355] Also, when directly viewing a light-emitting panel that emits light intermittently at a luminance of approximately 100,000 cd / m 2 , it feels extremely dazzling.

[0356] Such a light-emitting device 104 can be used, for example, in a security device. Specifically, when attacked by a thug, the light-emitting device 104 is intermittently emitted toward the thug. Thereby, the thug ​​​​​​​​​It can make timid crimes hesitate.

[0357] In addition, the light-emitting device 104 provided in a portable camera or a mobile phone with a camera can also serve as a camera flash and a security device. Note that the magnitude of the current supplied by the constant current power supply 140 may be changed according to the application and the ambient brightness. Specifically, the brightness when used as a security device may be set to be equal to or higher than the brightness when used as a camera flash.

[0358] Also, when the light-emitting device 104 is used as a warning light for a bicycle or the like, other passing vehicles and pedestrians can be made aware of its position. Thereby, the occurrence of accidents can be prevented.
