[0024] figure 1 It is a sectional view showing the liquid crystal display device according to the first embodiment of the present invention. The liquid crystal display device includes, for example, a first substrate 10 that is a light-transmitting substrate such as a glass substrate. A black matrix 12 is formed on the first substrate 10 .

Abstract

The black matrix has a shape in which a plurality of horizontal line portions which extend in the horizontal direction, and are aligned in the vertical direction, and a plurality of vertical line portions which extend in the vertical direction, and are aligned in the horizontal direction cross each other. The opening has a shape in which the convex portion is formed on one side, and a concave portion is formed on the other side in the horizontal direction. The spacer is arranged at an intersection portion of the vertical line portion and the horizontal line portion, by avoiding an intersection portion of the vertical line portion which is close to the convex portion of the opening at which a colored layer of a color having the highest transmittance is arranged and the plurality of horizontal line portions.

Description

technical field [0001] The present invention relates to a liquid crystal display device. Background technique [0002] A liquid crystal panel has a pair of substrates, and a spacer is provided on one of the substrates in order to maintain a gap between the pair of substrates (a liquid crystal enclosing space) (see Patent Document 1). An orientation film is formed on surfaces of the respective substrates facing each other, and an orientation film is formed on the spacer. Accordingly, protrusions are formed on the alignment film via the spacers. [0003] Existing patent documents [0004] Patent Document 1: Japanese Patent Laid-Open No. 2005-345819 [0005] In order to arrange the liquid crystal molecules in a certain direction, grooves in a certain direction are formed on the alignment film. When protrusions are formed on the alignment film via spacers, abnormal alignment occurs in a rubbing process for forming grooves. Alignment abnormality occurs along the rubbing dire...
