Abstract
A display device and a flat lamp that have simple structures and can be fabricated using simple fabricating processes, and a method of fabricating the display device and the flat lamp. The display device includes: a first substrate and a second substrate facing each other across a predetermined distance; barrier ribs defining light emitting cells with the first substrate and the second substrate; an anode electrode disposed in the light emitting cell; a conductive silicon layer disposed on an inner surface of one of the first and second substrates; an oxidized porous silicon layer, at least a part of which is disposed on the conductive silicon layer; and a gas contained in the light emitting cell. The fabrication method includes doping part of a silicon layer on the inner surface of the first or second substrate and changing another part of the silicon layer to an oxidized porous silicon layer.
