Abstract: A high-resolution field emission display that applies a field emission device(or a field emission array) being an electron source element to a flat panel display device. The field emission display includes an upper plate and a lower plate that fac each other, wherein the lower plate and the upper plate are vacuum-packaged in parallel positions. A dot pixel of the lower plate includes a high-voltage amorphous silicon thin film transistor formed on the glass substrate of the lower plate, a diode type field emission film partially formed on the drain of the high-voltage amorphous silicon TFT, a passivation insulation layer formed on the high-voltage amorphous silicon TFT and the lateral side of the diode type field emission film, and an electron beam focusing electrode/light-shading film which vertically overlaps with the high-voltage amorphous silicon TFT on some parts of the passivation insulation layer and is formed on a lateral side of the diode type field emission film. 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.
