An electro-optical panel having improved cracking resistance includes a substrate having scratches and cracks formed during a production process removed by etching.

Electro-optical panel, electronic appliance and production method of the electro-optical panel

In an electro-optic apparatus, a base electrically conductive film made from an ITO film, an optical reflection film made from a silver alloy film, a color filter layer, an organic insulating film serving as a flattening film, an inorganic insulating film made from a silicon oxide film or others, first driving electrodes made from an ITO film, and an alignment film are formed in that order in the first substrate. Second wiring patterns which connect mounting terminals to first inter-substrate electric-connection terminals are made from metal wiring formed together with the optical reflection film at the same time. The second wiring patterns are disconnected at an area exposed from a second substrate, and wiring formed together with first driving electrodes at the same time is formed at the area.

Electro-optic apparatus including reflection film with transmission holes and wiring patterns formed of same metal film as reflection film

A matrix-type liquid crystal display device for use in alphanumeric and television displays, and the like, has a screen in which division of images produced by the display screen resulting from assembly error is eliminated by means of reduction in the areas of the picture forming elements near the region where end portions of the signal electrodes project between control electrodes.
