Abstract: The present invention relates to displaying system having a display panel which comprises a sealing structure adapted for assembling a first substrate to a second substrate in an ODF process. The sealing structure comprises a sealant, applied between the substrates, and the panel comprises a black matrix, disposed along the first substrate, with a slot or windows disposed thereon for facilitating the passage of UV light. The sealant is at least partially exposed from the black matrix for curing by the UV light, which is projecting from the outer side of the first substrate. By using the mentioned structure, the dimensions of the LCD frame could be diminished, so that the displaying region could be efficiently utilized.
