PURPOSE: A method for forming a photoresist pattern is provided to be capable of stably forming the photoresist pattern by closing the opening portion of a vertical trench with high step using a DFR(Dry Film Resistor) layer. CONSTITUTION: A trench(102) having a high step is formed on a substrate(100). A DFR layer(110) is deposited on the substrate. A DFR pattern is formed by carrying out the first photolithography process on the resultant structure for closing only the opening portion of the trench. A photoresist layer is coated on the entire surface of the resultant structure. Then, a photoresist pattern is formed by carrying out the second photolithography process. Preferably, the DFR layer having a thickness of 1-70 μm is deposited at the adhesion temperature of 70-100 °C by using one selected from a group consisting of an adhesive lamination method, a melt lamination method, an extrusion lamination method, and a heat lamination method.

A dot pixel of the upper plate includes a transparent electrode formed on the glass substrate of the upper plate, and a red, green or blue phosphor formed on some parts of the transparent electrode. Therefore, the high-resolution field emission display device can obtain an effect of focusing the electron beam trajectory and a light-shading effect for the TFT at the same time, and thus remarkably enhance the performance and the resolution of the field emission display.
