The present invention relates to a plasma display panel comprising at least one first electrode body including a cathode; At least one second electrode body including an anode; And a separator sheet separating the first electrode assembly and the second electrode assembly from each other, the separator sheet including a plurality of folding parts, wherein the separator sheet comprises a first porous polymer base material, A first porous coating layer formed on one surface of the substrate and including a polymeric binder and facing the cathode; and a mixture of polymeric binder and inorganic particles formed on the other surface of the first porous polymeric substrate, And a second porous coating layer having a different composition, thickness or porosity from the first porous coating layer, and a lithium secondary battery comprising the electrode assembly. According to the present invention, there is provided an electrode assembly having a composition, By applying a separator having different porous coating layers formed on one surface thereof, So that the coating layer is completely without contact Alternatively mismatch (mismatch). |
