摘要： A flat fluorescent lamp is provided with one or more protrusions at the periphery thereof, which protrusion(s) extends outwardly beyond the edges of the two glass plates. A lamp holder receives the protrusion of the flat fluorescent lamp so as to hold the same in a manner that no edges of the two parallel glass plates touch or come into contact with the lamp holder.

摘要： In a production process for a transverse electrical field type active matrix liquid crystal display apparatus, a photolithographic step is eliminated to reduce the cost. There are formed on an insulating substrate carrying thin-film transistors as switching elements, drain electrodes 31 formed by a first low-resistance electrically conductive film 3, drain bus lines 31 connected to the drain electrodes 31, source electrodes 33 and pixel electrodes 34. Islands are formed on the resulting assembly by a semiconductor film. There are further formed on the resulting product gate electrodes 61, gate bus lines 62 and counter electrodes 63. Islands 71 are formed in the same pattern as that of the gate electrodes 61, gate bus lines 62 and the counter electrodes 63. The gate electrodes 61, gate bus lines 62, counter electrodes 63 and the islands 71 can be formed by a sole photolithographic step to reduce the number of the photographic steps and hence the cost.

摘要： Extraction wirings are respectively connected to a signal line of a switching element and a scanning line thereof, and led out to one side portion of a transparent insulating substrate. Conductive terminals respectively united with the extraction wiring are formed in tip end portions thereof, and a plurality of contact holes connected to the conductive terminals are formed on the conductive terminals so that a diver IC is mounted thereon by using conductive resin. Each of the extraction wirings is provided with a semiconductor film pattern in the vicinity of the contact hole for blocking the moisture in the conductive resin to reach the extraction wirings through an interlayer insulating film.
