<p>PURPOSE:To enable the low cost supply of a large-screen display cell provided with Trs in respective display picture elements. CONSTITUTION:The respectively independent Trs are tightly formed on a highly heat resistant high-polymer film 1, consisting of polyimide, etc., and after these Trs are adhered to another transfer substrate 7, the above-mentioned high- polymer film 1 is etched away. On the other hand, lead wires connecting the respective Trs are previously formed on a display substrate for a large area. The previous Trs are transferred to the positions corresponding to the lead wires of this display substrate while these Trs are electrically connected. The dense Trs are transferred in compliance with the display pitch and the transfer substrate 7 is so moved as to meet the next display picture element pitch. The densely formed Trs are coarsely and efficiently formed on the large-area display substrate by the repetition of the above-mentioned operations.</p> |
