ABSTRACT:
A projection type image display apparatus of the invention has a lamp mounting mechanism, which has an aluminum lamp holder (166) intervening between the lamp (16) and the resin lamp holder (167) and has a section exposed out of the resin lamp holder (167). The lamp (16) is securely fixed in position on the aluminum lamp holder (166) by mounting the lamp (16) on the aluminum lamp holder (166) from above and then folding the top section (166d) towards the top end of the lamp (16). This lamp mounting mechanism can suppress the temperature of the resin lamp holder without providing a cooling fan with a large amount of power and suppress fan noise, thereby simultaneously enabling uprating of the power of the lamp and downsizing of the image display apparatus.
