Liquid crystal display panel, liquid crystal display device provided with same, and bonding substrate for liquid crystal display panel

Abstract

A liquid crystal display panel (2) is provided with a first substrate (4) having a light blocking film (45), a plurality of color filters (46R, 46G, 46B, 46) and a display electrode (48) formed on a first transparent substrate (44); a second substrate (5) having a display electrode (51) formed on a second transparent substrate (50); a plurality of spacers (20, 21) for maintaining a distance between the first substrate (4) and the second substrate (5); and a sealing member (6) for sealing a liquid crystal between the first substrate (4) and the second substrate (5). At least the first substrate (4) or the second substrate (5) is provided with a protruding section (43) formed to surround a display area (40) in a peripheral region (42) between a display area (40) including a plurality of display pixels and a sealing area (41) sealed by the sealing member (6). The spacers (20, 21) include the first spacer (20) positioned in the display area (40) and the second spacer (21) positioned at the protruding section.

Description

technical field [0001] The present invention relates to a color type liquid crystal display panel having a color filter, a liquid crystal display device having the same, and a bonding substrate for a liquid crystal display panel. Background technique [0002] In recent years, liquid crystal display devices equipped with liquid crystal display panels have become popular not only in relatively small information communication devices such as portable information terminal devices but also in relatively large electronic devices such as monitors and car navigation devices. Such a liquid crystal display panel generally has a structure in which a liquid crystal layer is interposed between a pair of transparent substrates on which electrodes for applying a voltage to the liquid crystal are formed. The liquid crystal layer is held between a pair of transparent substrates by a sealing material arranged around a display area including a plurality of pixel portions. [0003] In a liquid...

Problems solved by technology

As a result, when a member having a compressive modulus smaller than that of the spacer 97 is used as the spacer 96, it is difficult to uniformize the thickness D of the liquid crystal layer over the entire display area.
