[0122] This embodiment will now be described in conjunction with a substrate with spacers used in a liquid crystal display panel. The substrate with spacers according to the present invention can be used not only in liquid crystal display panels but also in organic EL panels, inorganic EL panels, plasma panels, field emission panels, electrochromic panels, and the like. The liquid crystal panel can be applied not only to a liquid crystal display panel, but also to an image displacement panel that optically shifts pixel positions sequentially, and a parallax barrier panel that can display three-dimensional images. The image displacement panel includes at least one set of liquid crystal panels modulating the polarization states of light emitting elements and birefringent elements combined with the liquid crystal panel for shifting an optical path according to the polarization state of light from the liquid crystal panel. The parallax barrier panel is combined with an image displ...

Abstract

A liquid crystal display panel includes two substrates (1a and 1b) fixed together by a seal member (2) with their main surfaces opposed to each other, liquid crystal (6) sealingly stored in a region surrounded by the two substrates (1a and 1b) and the seal member (2), and a plurality of columnar spacers (5) arranged in a region surrounded by the two substrates (1a and 1b) and the seal member (2). A number density of the columnar spacers (2) in a low-density region (32) near the inner side of the seal member (2) is smaller than that in a high-density region (31) inside the low-density region (32). The substrate with the spacer has the substrate and the spacer formed on the substrate. The spacer has at least a first spacer portion, and a second spacer portion formed above the first spacer portion. An upper portion of the first spacer has a larger diameter than a bottom of the second spacer portion.

Description

technical field [0001] The invention relates to a liquid crystal display panel and a manufacturing method thereof, in particular to a liquid crystal display panel including column spacers and a manufacturing method thereof. [0002] The invention also relates to a substrate provided with spacers arranged on the substrate. The substrate with the spacer according to the present invention is bonded to the opposite substrate so that a constant interval can be maintained between the substrates. Background technique [0003] The liquid crystal display panel includes a substrate provided with driving elements for driving liquid crystals, and a substrate provided with counter electrodes facing each other, and these substrates are bonded together with their main surfaces facing each other with an interval of several micrometers therebetween. [0004] FIG. 11 is a schematic cross-sectional view of a liquid crystal display panel according to the prior art. For simplicity, FIG. 11 doe...
