摘要： PROBLEM TO BE SOLVED: To prevent a backlight from leaking at a liquid crystal sealing hole part, and to make it possible to obtain excellent display quality, by arranging a black matrix in the liquid crystal sealing hole part. SOLUTION: A black matrix BM consisting of an organic resin such as aclylic, epoxy, polymido resin, added with carbon black, black organic pigment, etc., is formed in a prescribed pattern on a transparent glass substrate SUB2, and color filters FIL (R), (G), (B) are formed respectively in prescribed patterns on it. The peripheral part of a pixel part is formed into a frame shape with a proper width and the pattern light shielding the liquid crystal sealing hole INJ part for preventing a light leakage from the backlight when a liquid crystal display element is assembled in a module. In such a manner, since the BM is arranged on the liquid crystal sealing hole INJ part, the light from the backlight is interrupted in the INJ part, and the light leakage from the liquid crystal sealing hole INJ part is prevented, and the display quality is improved.

摘要： PURPOSE: To form the pattern of alignment marks with high accuracy in a thin layer for a black matrix by using an org. material. CONSTITUTION: This production method includes at least the following processes. (a) A negative-type photosensitive resist thin layer consisting essentially of an org. material to which a light-absorbing material is mixed is formed on a substrate. (b) The photosensitive resist thin layer in a specified part out of the effective area is removed by laser ablation method to leave an alignment mark part. (c). The photosensitive resist thin layer is exposed by using an exposure mask having an opening corresponding to the black matrix pattern and the alignment mark part. (d) The photosensitive resist is developed to form alignment marks and a black matrix. (e) The resist is baked to harden the alignment marks and the black matrix. (f) Plural color filters are formed.

摘要： PROBLEM TO BE SOLVED: To provide a display device which prevents the light leakage in sealing parts and the peeling of the substrates in the sealing parts and has excellent display quality and reliability and wide display regions. SOLUTION: A black matrix BM consists of a black org. resin and a sealing material SL is provided with light shieldability. The light shieldability and optical characteristics of color tones of the light shieldable sealing material SL and the black matrix BM are equaled to each other. The light absorbance (OD value) in the visible light region of both is 1.5 to 3.5 and the color tones in terms of a C light source are in a range of 0.2 to 0.5 in both of x and y. The light shieldable sealing material SL is formed by adding a black coloring agent to a thermosetting type epoxy resin consisting of a phenolic resin of tri- or higher nuclides as a hardener.
