Abstract:
A color filter layer is formed on a glass substrate of a counter substrate. A bank pattern is formed of the same material as a red color-filter portion, a green color filter portion and a blue color filter portion of the color filter layer at the outside of the color filter layer on the glass substrate in the same step. A light shielding material is coated in a bank between the bank pattern and the color filter layer to form a light shielding layer. The light shielding layer can be formed so as to be continuous with the peripheral edge of the color filter layer. The light shielding layer is less likely to overlap with the inside of a display frame portion of the liquid crystal panel, and the aperture ratio is less likely to be reduced. The number of manufacturing steps of the light shielding layer is reduced.
