Abstract
An evaporating device including: a material retaining part for being filled with an evaporating material and heating the evaporating material; an opening for dispersing the evaporating material vaporized from the material retaining part toward an evaporated member; and a high-temperature body disposed between the material retaining part and the opening, the high-temperature body being heated to a temperature higher than a temperature of the evaporating material heated in the material retaining part.
Claims9
An evaporating device comprising:
- a material retaining part for being filled with an evaporating material and heating the evaporating material;
- an opening for dispersing said evaporating material vaporized from said material retaining part toward an evaporated member;
- and
- a high-temperature body disposed between said material retaining part and said opening, the high-temperature body being heated to a temperature higher than a temperature of said evaporating material heated in said material retaining part.
An evaporating method for heating an evaporating material in a state of said evaporating material being filled in a material retaining part, vaporizing said evaporating material, and dispersing the vaporized said evaporating material from an opening to an evaporated member, said evaporating method comprising the steps of:
- disposing a high-temperature body between said material retaining part and said opening;
- and
- heating said high-temperature body to a temperature higher than a temperature of said evaporating material heated in said material retaining part when evaporation is performed.
An organic electroluminescent element having a first electrode, an organic layer including a light emitting layer, and a second electrode on a substrate,
- wherein said light emitting layer is formed by evaporation by an evaporating method for heating an organic material in a state of said organic material being filled in a material retaining part, vaporizing said organic material, and dispersing the vaporized said organic material from an opening to said substrate, the evaporating method including disposing a high-temperature body between said material retaining part and said opening, and heating said high-temperature body to a temperature higher than a temperature of said organic material heated in said material retaining part.
A display device using an organic electroluminescent element, the organic electroluminescent element having a first electrode, an organic layer including a light emitting layer, and a second electrode on a substrate,
- wherein said light emitting layer is formed by evaporation by an evaporating method for heating an organic material in a state of said organic material being filled in a material retaining part, vaporizing said organic material, and dispersing the vaporized said organic material from an opening to said substrate, the evaporating method including disposing a high-temperature body between said material retaining part and said opening, and heating said high-temperature body to a temperature higher than a temperature of said organic material heated in said material retaining part.
A method for manufacturing a display device, said method including an evaporating step of heating an evaporating material in a state of said evaporating material being filled in a material retaining part, vaporizing said evaporating material, and dispersing the vaporized said evaporating material from an opening to an evaporated member,
- wherein a high-temperature body is disposed between said material retaining part and said opening, and said high-temperature body is heated to a temperature higher than a temperature of said evaporating material heated in said material retaining part when evaporation is performed.
