When an alignment filmand an overcoating filmare formed by flexography on the front side of a second transparent substrate, on which color filtersR,G, andB are formed at a predetermined same-color pitch P, during the procedure for manufacturing a liquid crystal device, the pitch of meshes of an anilox roller used in flexography and the pitch of pitches formed on the surfaces of projections of a letterpress are set to be equal to the same-color pitch Pof the color filtersR,G, andB, thereby preventing moir&#xe9;.

Method of manufacturing electro-optical device by flexography for reduced moire

A liquid-crystal display panel 20 comprises a first substrate 30 having an IC chip 60 mounted on the margin thereof and a second substrate 50 opposed to the first substrate 30 except the margin 31 on which the IC chip 60 is mounted. The first substrate 30 has two rows of pads 33 and 34, which are used to attach the IC chip 60, arranged nearly parallel to a side of the second substrate 50 adjoining the margin 31 on the margin 31 on which the IC chip 60 is mounted. A wiring pattern of lines passing through the pads on the row of pads 33 near the adjoining side of the second substrate 50 out of the rows of pads 33 and 34 includes a straight wiring-pattern part 38 extended straight to the inside of an IC chip mounting region 40 or a region in which the IC chip 60 is mounted. As such, a liquid-crystal display panel is provided which is capable of being tested for lighting prior to mounting of an IC chip even though a wiring pattern surrounding the IC chip on a liquid-crystal substrate is very short.

Inspectable liquid-crystal display panel and method of inspecting same

A liquid crystal panel substrate is used as a translucent substrate with a liquid crystal panel. The liquid crystal panel has a display region and a non-display region disposed outside of the display region. A plurality of electrodes are disposed across the display region and the non-display region of the liquid crystal panel. Each electrode has a width differing between the display region and the non-display region.

Liquid crystal panel substrate, its fabrication method, liquid crystal

A liquid-crystal display panel having different-pitch transparent electrodes to be inspected, a first inspection region defined for stripe electrodes on a transparent substrate included in the liquid-crystal display panel, and a second inspection region defined for other electrodes, allows for the use of multi-purpose inspection probes arranged at regular intervals to inspect all the electrodes without difficulty. The first inspection region includes a plurality of stripe electrodes arranged at regular first inspection interval, a plurality of stripe electrodes arranged at intervals different from the first interval, with the stripe electrodes connected to first inspection electrodes included in the second inspection region. When the first inspection electrodes are located in the second inspection region, their spacing is arranged at a second inspection interval characteristic of the second inspection region so they can be inspected with inspection probes spaced at the second inspection interval.
