Patent ID: 6917402

Claim:
A method of fabricating an opposite substrate with microlenses for a liquid crystal display panel, said opposite substrate being opposite through a liquid crystal layer to a driving substrate which has a plurality of pixel electrodes and a plurality of switching elements for individually switching said plurality of the pixel electrodes, said opposite substrate being provided with the microlenses formed on a back side of the side opposed to a front side faced to the driving substrate, the method comprising the steps of: forming a plurality of concave portions at least one surface of a light-transmitting glass substrate, each of said concave portions having a curved surface on a bottom wall thereof; filling, into said concave portions, a transparent material having a refraction index greater than that of said light-transmitting glass substrate to form microlenses; bonding an additional light-transmitting glass substrate onto the surface of the light-transmitting glass substrate which has the microlenses and to thereby obtain a substrate with microlenses, said concave portions being opened towards the additional light-transmitting glass substrate in the substrate with the microlenses; forming a mask pattern either on the other surface of the additional light-transmitting glass substrate without any microlenses or on a transparent film formed on the other surface of the additional light-transmitting glass substrate, the mask pattern being arranged at least on regions opposite to the switching elements and withstanding etching of the light-transmitting substrate or the transparent film; etching the additional light-transmitting glass substrate or the transparent film by using the mask pattern as a mask to form concave portions having a predetermined depth; forming a light shielding film on the additional light-transmitting glass substrate on which the concave portions are formed, by successively stacking a high reflection thin film of a high reflection material and a low reflection thin film of a low reflection material to form a stacked light shielding film; and removing the mask pattern and the light-shielding film formed on the mask pattern to embed the stacked light-shielding film in the concave portions.
