  • Patent number: 9588379
    Abstract: A curved liquid crystal display panel includes a first substrate, a liquid crystal layer and a second substrate. The first substrate includes a column spacer fixedly anchored to and protruding therefrom. The second substrate includes a stepless preliminary contact area corresponding to a contact-making free end of the column spacer where the preliminary contact area is part of a larger and also non-stepped area. The second substrate is combined with the first substrate to receive the liquid crystal layer therebetween. The non-stepped area is dimensioned to account for shift of the where the contact-making free end of the column spacer makes contact due to the curvature of the first and second substrates.
