Abstract

An object of the invention is to improve patterning accuracy while maintaining low cost, high throughput and a high degree of freedom of an optical material in a matrix type display device and a manufacturing method thereof. In order to achieve the object, surface features, including structural surface features, a desired distribution of water repellency, liquid repellency, hydrophilicity and lyophilicity, or a desired potential distribution are formed by utilizing first bus lines in a passive matrix type display device or utilizing scanning lines, signal lines, common feeder lines, pixel electrodes, an interlayer insulation film, or a light shielding layer in an active matrix type display device. A liquid optical material is selectively coated at predetermined positions by utilizing the surface features.

Claims

1. A method of manufacturing a display device, the method comprising:

forming a recess on a peeling layer disposed on a peeling substrate so as to form a difference in height between a predetermined position and a periphery of the predetermined position, the predetermined position being lower than the periphery of the predetermined position;

applying an optical material or a liquid precursor to a surface at the predetermined positions; and

transferring a layer to be transferred onto a display substrate.

2. The method of manufacturing a display device according to claim 1, wherein applying one of the optical material and the liquid precursor to the surface at the predetermined positions is performed by an ink jet method.

3. A method of manufacturing an electro-luminescent device, the method comprising:

forming a recess on a peeling layer disposed on a peeling substrate so as to form a difference in height between a predetermined position and a periphery of the predetermined position, the predetermined position being lower than the periphery of the predetermined position;

applying an optical material or a liquid precursor to a surface at the predetermined positions; and

transferring a layer to be transferred onto a display substrate.

4. A method of manufacturing a display device, the method comprising:

enhancing a lyophilicity at a predetermined position relative to a lyophilicity at a peripheral region around the predetermined position on a peeling layer disposed on a peeling substrate;

applying one of an optical material and a liquid precursor to a surface at the predetermined positions; and

transferring a layer to be transferred onto a display substrate.

5. A method of manufacturing an electro-luminescent device, the method comprising:

enhancing a lyophilicity at a predetermined position relative to a lyophilicity at a peripheral region around the predetermined position on a peeling layer disposed on a peeling substrate;

applying one of an optical material and a liquid precursor to a surface at the predetermined positions; and

transferring a layer to be transferred onto a display substrate.
