Abstract: PURPOSE:To improve reliability by independently providing heat radiation metal and a metal part on which a semiconductor chip is mounted, and closely bonding the heat radiation metal and the metal part. CONSTITUTION:There are provided a semiconductor chip 1, a gold wire 2 for connection of the semiconductor chip 1, a metal lead frame 3 to which the gold wire 2 is connected, an interface 6 between semiconductor resin 5 and heat radiation metal 7, the heat radiation metal 7, metal 8 on which the semiconductor chip 1 is mounted, and a junction part 9 between the heat radiation metal 7 and the metal 8. The metal part 8 and the resin 5 are constructed such that they are not brought into close contact while the metal part 8 on which the semiconductor chip 1 is mounted and the resist 5 are maintained in their contact property. Hereby, there is eliminated inconvenience due to a difference between thermal expansion coefficients of the semiconductor sealing resin and the heat radiation metal, and hence there is improved raliability.

Title: Liquid crystal display element
Inventor: KOJIMA KEN
IPC: G02F1/1347
Filed: 1989-12-27
Abstract: PURPOSE:To obtain a good display of high contrast which is free from coloration over a wide temp. range by using a liquid crystal material having the temp. dependency of specific refractive index anisotropy. CONSTITUTION:The max. transmittance of light in the liquid crystal display element of a two layer type laminated with a display cell 10 and a compensation cell 20 is higher as the difference between the values of the product of the value of the refractive index anisotropy DELTAn and the thickness d of the liquid crystal layer in the display cell 10 and the compensation cell 20, i.e. the difference between the values of DELTAn.d is smaller. The light transmittance at a high temp. can, therefore, be increased by selecting the liquid crystal material used for the compensation cell 20 in such a manner that the difference in the value of the DELTAn.d between the display cell 10 and the compensation cell 20 decreases on the high-temp. side. Since the value of the DELTAn20, d20 of the compensation cell 20 is set smaller than the value of the DELTAn10, d10 of the display cell 10, the compensation of the coloration of the display is sufficient. The good display of the high contrast which is free from the coloration over the wide temp. range is obtd. in this way.
