- the inventor of the present application has found that the following problems occur with respect to a conventional organic EL panel.
- the organic EL panel has a configuration in which an organic EL element is disposed between two glass substrates.
- An organic EL element generally includes a light emitting layer that emits light to display an image.
- the characteristics of the light emitting layer are irreversibly deteriorated due to a temperature increase due to heat generation of the light emitting element itself. .
- the organic EL panel is a self-luminous display panel, a backlight like a liquid crystal display panel is not necessary. Therefore, for example, a thin organic EL panel having a thickness of about 1 mm to 3 mm can be realized.
- organic EL display devices such as a television receiver (television) equipped with an organic EL panel are also required to be thin.
- the thickness is desirably as thin as possible.
- a heat radiating sheet which is a sheet-like member formed by rolling a metal plate having a high thermal conductivity (for example, aluminum), is exemplified.
- the heat dissipation efficiency of the organic EL panel can be improved by pasting this heat dissipation sheet on the organic EL panel so as to cover the back of the panel.
- the inventor of the present application has found that when the organic EL panel unit is warped as described above, the direction of the warpage is affected by the rolling direction of the heat dissipation sheet.
- the “rolling direction” is defined as, for example, a direction orthogonal to the axis of a roller used for rolling a metal plate that is a material of the heat dissipation sheet.
- FIG. 1 is a schematic diagram showing the relationship between the rolling direction of the heat-dissipating sheet 270 and the warping direction of the organic EL panel unit 210, which is the result of an experiment conducted by the inventor of the present application.
- the organic EL panel unit 210 is configured by attaching a heat dissipation sheet 270 made of aluminum to the back surface of the organic EL panel 200 as shown in FIG.
- the organic EL panel unit 210 when the organic EL panel unit 210 is cooled by, for example, the atmosphere of the installation environment, the organic EL panel 200 and the heat radiation sheet 270 have different coefficients of thermal expansion (linear expansion coefficients), so that the organic EL panel unit 210 is deformed. Occurs.
- the heat dissipation sheet 270 is arranged so that the rolling direction of the heat dissipation sheet 270 is parallel to the long side of the organic EL panel 200 (including substantially parallel, the same applies hereinafter). The following deformations are observed when.
- the organic EL panel 200 is observed to bend in the short side direction (X-axis direction). That is, the organic EL panel unit 210 as a whole is warped in the short side direction.
- an object such as a heat-dissipating sheet is curved (warped) in a certain direction, it means that the object is curved (warped) in the circumferential direction of a cylinder centering on an axis orthogonal to the direction. .
- the above-described warpage of the organic EL panel unit 210 as a whole is considered to be mainly caused by the following plurality of reasons.
- the organic EL panel 200 dissipates heat when the whole is cooled. It is pulled by the sheet 270. For this reason, the organic EL panel unit 210 is warped toward the heat dissipation sheet 270.
- the heat radiating sheet 270 when the heat radiating sheet 270 is manufactured, it is rolled with a roller. In this rolling, in order to make the thickness of the heat radiating sheet 270 uniform, for example, it is rolled in a state where the pressure is not constant in a direction orthogonal to the rolling direction.
- the central portion in the direction orthogonal to the rolling direction is extended with a higher pressure than both ends in the direction orthogonal to the rolling direction.
- the heat dissipation sheet 270 has a non-uniform crystal structure in the direction orthogonal to the rolling direction, which causes the heat dissipation sheet 270 to change in the direction orthogonal to the rolling direction rather than the rolling direction due to temperature changes.
- the property of being easily expanded and contracted is generated.
- the direction perpendicular to the direction in which expansion or contraction due to temperature change appears is the rolling direction.
- the organic EL panel is incorporated in an organic EL display device such as a television in a state where the organic EL panel is held in, for example, a metal chassis disposed on the back side of the organic EL panel. Therefore, the deformation of the organic EL panel unit (organic EL panel) may be suppressed by the chassis.
- the chassis since the chassis is also required to be thin, the chassis itself has to adopt a structure in which it is difficult to form a flat surface. That is, when the chassis plays a role of suppressing the deformation of the organic EL panel, the result is that the deformation of the chassis itself also appears in the organic EL panel.
- the organic EL panel unit itself including the organic EL panel and the heat dissipation sheet has a configuration for achieving both efficient heat dissipation and suppression of deformation due to temperature change.
- the present disclosure has been made on the basis of such knowledge, and as a result of intensive studies by the inventors of the present application, the heat dissipation of the organic EL panel is efficiently performed, and the linear expansion coefficient of the organic EL panel, for example,
- the inventors have obtained an idea about the structure of the organic EL panel unit that suppresses the deformation of the organic EL panel due to a temperature change even when the linear expansion coefficient of the heat dissipation sheet made of aluminum or the like is different.
