Photosensitive paste composition, barrier rib prepared using the composition and plasma display panel comprising the barrier rib

Photosensitive paste compositions, barrier ribs of plasma display panels (PDPs) including the same, and PDPs including the barrier ribs are provided. More particularly, a photosensitive paste composition includes an organic component and an inorganic component, where the organic component and the inorganic component each have an average refractive index of less than 1.5. The organic component used in the photosensitive paste composition is not harmful to the human body, is inexpensive, is generally easily obtained, and succumbs readily to thermal decomposition. Accordingly, using such an organic component, barrier ribs of PDPs having high resolution and high compactness by exposure to light only once can be prepared.
