Method of manufacturing display device and display device

A method of manufacturing a display device, comprising the steps of:

• forming a positive type photoresist above a surface of a first transparent substrate that has a transistor formed on the surface, the transistor having a source electrode, a gate electrode, and a drain electrode;
• radiating light to the first transparent substrate having the positive type photoresist formed thereabove from a back surface side of the first transparent substrate to expose the positive type photoresist, the positive type photoresist being selectively exposed by using the source electrode, the gate electrode, and the drain electrode of the transistor as a mask;
• developing the exposed positive type photoresist to selectively leave portions of the positive type photoresist located above the source, gate, and drain electrodes of the transistor so as to form spacers disposed respectively above the source, gate, and drain electrodes;
• and
• laminating a second transparent substrate above the first transparent substrate through the spacers so that a space is formed between the first transparent substrate and the second transparent substrate.
