A timepiece including: a dial; a windshield glass having a plurality of curved surfaces that differ from each other in curvature; and a hand disposed between the dial and the windshield glass, wherein the windshield glass includes: a first curved surface having a first curvature and including a center of the windshield glass; a second curved surface disposed adjacent to the first curved surface and having a second curvature larger than the first curvature; and a third curved surface disposed adjacent to the second curved surface and having a third curvature larger than the second curvature, a thickness of the first curved surface and a thickness of the second curved surface are equal, and in plan view, a distal end of the hand is disposed on a center C side of the windshield glass with respect to a boundary between the second curved surface and the third curved surface.

Timepiece

An electro-optical apparatus having a color filter, and in particular, such an electro-optical apparatus having a high information content, includes a metal layer which serves as both a light shielding layer and as an electrical conductor so that the escape of light between display elements is prevented to improve contrast and also so that the wiring resistance is reduced to reduce rounding of an applied waveform to thereby prevent cross-talk, the apparatus thus being constructed to readily achieve high-image quality. A color filter is disposed on at least one of a pair of transparent substrates which hold therebetween a liquid crystal layer in cooperation with a sealing member. Transparent display electrodes are disposed above the color filter, with a smoothing layer interposed between the electrodes and the color filter. A light shielding layer formed from, e.g., a metal layer formed in a stripe-shaped patter between adjacent columns of color filter elements of the color filter, serves as an electrical conductor and is electrically connected with the transparent display-electrodes via through-holes formed in the color filter and the smoothing layer.

Electro-optical apparatus with metal light shield and conductor between

A method of forming a color filter substrate having pixels of at least two different colors by use of a negative photoresist material of the last color deposited. The negative photoresist is coated over the pixels and the exposed surface of the substrate. The back of the substrate is then exposed to a light source at a wavelength blocked by the formed pixels so that any of the negative photoresist material directly on the transparent substrate is activated by the light from the light source and remaining material is removed.
