Abstract
A transfer substrate includes a transfer material layer on a support substrate via a light absorbing layer. Antireflection patterns for preventing light reflection on an interface of the support substrate and the light absorbing layer are provided between the support substrate and the light absorbing layer. Thickness of this antireflection patterns is set to a value with which an absorptance of light having a predetermined wavelength absorbed in the light absorbing layer is maximized.
Claims7
A transfer method of transferring a transfer material layer on a surface of a transfer substrate onto a receptor substrate by thermal transfer, comprising the steps of:
- preparing a transfer substrate provided with antireflection patterns, a light absorbing layer, and a transfer material layer on a light transmissive support substrate in this order;
- arranging, in a state in which the transfer material layer faces the receptor substrate side to which the transfer material layer is transferred, the transfer substrate to be opposed to the receptor substrate;
- and
- irradiating light having a predetermined wavelength from the support substrate side such that the light absorbing layer and the antireflection patterns absorb the light and convert the light into heat to thermally transfer selective portions of the transfer material layer that are on the antireflection patterns to the receptor substrate side.
A method of manufacturing a display device in which light emitting elements having functional layers containing a light emitting material held between first electrodes and a second electrode are formed to be arrayed on a device substrate, the method of manufacturing a display device comprising:
- preparing a transfer substrate provided with antireflection patterns, a light absorbing layer, and a transfer material layer containing a light emitting material on a light transmissive support substrate in this order;
- arranging, in a state in which the transfer material layer faces a first electrode formation surface side on the device substrate, the transfer substrate to be opposed to the device substrate;
- irradiating light having a predetermined wavelength from the support substrate side such that the light absorbing layer and the antireflection patterns absorb the light and convert the light into heat to thermally transfer selective portions of the transfer material layer that are on the antireflection patterns onto the first electrode in the device substrate to form the functional layers;
- and
- forming the second electrode on the device substrate to hold the functional layers between the first electrodes and the second electrode.
