Abstract
A liquid crystal display panel (1x) includes an active matrix substrate (3), a liquid crystal material (40), and a color filter substrate (30), wherein a spacer (33) is provided between the active matrix substrate (3) and the color filter substrate (30), and the color filter substrate (30) includes a step section (7) for restricting a movement of a spacer, the step section being provided so as to surround the spacer (33). This makes it possible to restrict the movement of the spacer in the liquid crystal display panel, thereby improving evenness of a cell gap.
Claims30
A liquid crystal display panel comprising:
- a first substrate including a transistor, a pixel electrode, and a signal line;
- a liquid crystal material;
- and
- a second substrate including a counter electrode and a light shielding layer, wherein:
- a spacer is provided between the first and the second substrates;
- and
- one of the first and the second substrates includes a step section for restricting a movement of the spacer, the step section being provided so as to surround the spacer.
A method for manufacturing a color filter substrate that faces, in a liquid crystal display panel, an active matrix substrate via a spacer, the method comprising the steps of:
- providing plural colored layers at intervals on a transparent substrate;
- providing a negative type black photosensitive resin film on the colored layers and in a gap formed by adjacent colored layers;
- carrying out exposure to a front surface of the negative type black photosensitive resin film by use of a mask that has a pattern surrounding a thin film section forming region in the gap formed by the adjacent colored layers;
- carrying out exposure to a back surface of the negative type black photosensitive resin film by use of the colored layers as a mask;
- and
- carrying out development such that the negative type black photosensitive resin film on the colored layers is removed and that the negative type black photosensitive resin film in the thin film section forming region is removed to a given depth from a surface of the negative type black photosensitive resin film.
