Abstract:
1. An LCD panel comprising: a first substrate comprising a first substrate material, a plurality of thin film transistors formed on the first substrate material, each thin film transistor having a drain electrode, and an organic layer formed on the thin film transistor and including a color filter layer; a second substrate disposed opposite to the first substrate and comprising a second substrate material; a main column spacer having a first end connected to the first substrate, and a second end connected to the second substrate; a sub column spacer having a first end connected to one of the first and second substrates, and a second end being spaced apart from the other one of the first and second substrates; and a recessed portion formed in at least one of the first and second substrates corresponding to the sub column spacer, wherein the main column spacer and sub column spacer are each formed on a different thin film transistor of the plurality of thin film transistors.
