An electron emission device includes a substrate with an effective area and a pad area placed external to the effective area. Cathode electrodes are formed on the substrate. Electron emission regions are formed at the cathode electrodes within the effective area. Gate electrodes are separately insulated from the cathode electrodes by interposing an insulating layer, and have opening portions to expose the electron emission regions. The respective gate electrodes have an effective portion located at the effective area with a first line width, and a pad portion located at the pad area with a second line width. When the line width subtracted from the first line width by the whole line width of the opening portions placed in the width direction of the effective portion is defined as an effective line width, the second line width is established to be larger than the effective line width.
