Method for manufacturing display element, manufacturing apparatus of display element and display device

摘要

A manufacturing apparatus of display element which forms highly reliable drive circuits or thin-film transistors on a flexible substrate, a manufacturing method, and a highly reliable display element are provided. A display element (50) includes a flexible substrate (FB), a first partition wall and second partition wall (BA) formed by pressing the flexible substrate, a lyophobic surface (PJ) formed on surfaces of the first partition wall and the second partition wall, and electrodes (S, P) formed by applying droplets onto a groove portion formed between the first partition wall and second partition wall. It is also possible for a lyophilic surface to be formed on the surface of the groove portion (GR) between the first partition wall and second partition wall (BA).

主权项

1. A method for manufacturing a display device having a plurality of pixel elements, thin-film transistors (TFTs), and bus lines on a flexible substrate which is fed in a longitudinal direction, the method comprising:
(a) a lyophobic property imparting process for imparting a lyophobic property to convex portions of a plurality of partition walls, the lyophobic property being a state difficult for a liquid to bond with the convex portions of the plurality of partition walls, the plurality of partition walls being formed on a flexible substrate by convexity and concavity to correspond to each area of a plurality pixel elements, thin-film transistors (TFTs), and bus lines; (b) a first droplet applying process for applying droplets of liquid material to form a first layer of the pixel elements, the TFTs, or the bus lines, in the concave portions; (c) a lyophilic property imparting process for imparting a lyophilic property to a surface of the substrate or a surface of the first layer by applying an ultraviolet (UV) light to a same shape area of a second layer which corresponds to one or more of the pixel elements, the TFTs, or the bus lines, the lyophilic property being a state easy for the liquid to bond with the surface of the substrate or the surface of the first layer; and (d) a second droplet applying process for applying droplets of liquid material to form the second layer of the pixel elements, the TFTs, or the bus lines on the same shape area imparted the lyophilic property by the UV light.
