摘要:
The present invention provides an in-plane switching type liquid-crystal display panel using spacer beads that is capable of preventing defective alignment of liquid crystal around the spacer beads to prevent leakage of light and to constantly sustain superior display quality. According to the present invention, a liquid-crystal display panel includes an electrode substrate, an opposing substrate, liquid crystal sandwiched between the electrode substrate and the opposing substrate, a large number of raised portions formed in a distributed manner in positions that correspond to a light shield film on the opposing substrate, and a large number of spacer beads retained between the electrode substrate and the raised portions and forming a gap between the electrode substrate and the opposing substrate, wherein voltage is applied to the pixel electrodes to produce electric fields approximately in parallel with a plane defined by the electrode substrate so that the liquid crystal reacts in the in-plane direction of the first substrate on the basis of the electric fields, and wherein the spacer beads are surface-treated to have adhesiveness so that the spacer beads adhere at least to the first substrate or the raised portions.
