PROBLEM TO BE SOLVED: To provide a technology for efficiently releasing heat from a driver IC.SOLUTION: A liquid crystal display device includes: an FPC 5; a front frame 26; and a rear frame 27. The FPC 5 includes: a GND solid pattern part 5c configured so as to be made close to or brought in contact with the front frame 26 for transferring heat transferred from metal wiring 2b to the front frame 26; and a GND solid pattern part 5d configured so as to be made close to or brought in contact with the rear frame 27 for transferring heat transferred from the metal wiring 2b to the rear frame 27. The GND solid pattern part 5c is configured so as to be pressed against the front frame 26 with the restoring force of the folded FPC 5. 【課題】ドライバＩＣを効率よく放熱することが可能な技術を提供することを目的とする。【解決手段】液晶表示装置は、ＦＰＣ５とフロントフレーム２６及びリアフレーム２７とを備える。ＦＰＣ５は、フロントフレーム２６に近接または接触されることによって金属配線２ｂから伝わった熱をフロントフレーム２６に伝えるＧＮＤベタパターン部５ｃと、リアフレーム２７に近接または接触されることによって金属配線２ｂから伝わった熱をリアフレーム２７に伝えるＧＮＤベタパターン部５ｄとを備える。ＧＮＤベタパターン部５ｃは、折り曲げられたＦＰＣ５の復元力によって、フロントフレーム２６に押圧される。【選択図】図４
