Liquid crystal display device
View Patent ↗The liquid crystal display (LCD) device of the present invention includes a LCD panel and a resin-molded frame that houses the LCD panel, the LCD panel including first and second substrates, and a liquid crystal layer sandwiched between the first and second substrates. The two-dimensional shapes of the first and second substrates are rectangles having longer and shorter sides, the longer side of the first substrate being longer than that of the second substrate. The first substrate has a non-overlapping area that does not overlap with the second substrate. Among the four corners of the first substrate, the non-overlapping area of the first substrate has two corners adjacent to each other. At least one of the two corners forms a chamfered structure having a diagonal side that intersects the longer and shorter sides of the first substrate with the diagonal side inclined to the longer and shorter sides.
