Method for manufacturing quantum dot display device and corresponding quantum dot display device

A method for manufacturing a quantum dot display device, comprising:

• providing an array substrate and a counter substrate opposite to each other;
• printing an alignment solution containing a quantum dot material onto a side of the array substrate facing the counter substrate;
• removing a solvent in the alignment solution printed onto the side of the array substrate facing the counter substrate;
• after removing the solvent, heating the array substrate;
• and
• providing a backlight source at a side of the array substrate facing away from the counter substrate wherein the printing comprises relief printing, wherein the relief printing comprises:
• dropping the alignment solution onto an anilox roller by a dispenser;
• by means of rotation of the anilox roller and a printing roller on which a relief printing plate is mounted, transferring the alignment solution dropped onto the anilox roller to the relief printing plate, wherein a rotation direction of the printing roller is opposite to that of the anilox roller and a ratio of linear velocities thereof is within a certain range, and wherein the relief printing plate is at least partially in contact with and pressed against the anilox roller during rotation with the printing roller;
• and by means of rotation of the relief printing plate and translation of the array substrate, transferring the alignment solution transferred to the relief printing plate onto the array substrate, wherein during the transferring process, the relief printing plate is externally tangent to the array substrate and has a same linear velocity with the array substrate.
